Buying a laptop, check if it has nVidia Optimus, its purpose is infuriate you
- CSDude 13y agoI have a Samsung NP700G7C, a gamer laptop, it comes with optimus disabled, even the GPU supports it (GTX675M). It cannot be enabled, computer is unaware of Intel HD4000 inside. As I have seen from a friend with another gamer laptop, he always have problems when launching games, they sometimes want to use Intel HD4000. And it goes on even if you explicitly state that "open this with nvidia gpu". So sad.

- speeder 13y agoLike I wrote in the post, I had to DOWNGRADE the driver, because a upgrade made it STOP working at all, GPU got 100% disabled, not even nVidia control panel launched anymore.

- kevinbowman 13y agoI have a Lenovo Thinkpad W520, with nVidia Optimus. What they didn't tell me was that the external VGA port is hard-wired to the nVidia GPU, so I can't use it at all when on the Intel GPU. Choice: battery life or external VGA? To make matters worse, it's a reboot to switch between them, and since I use Ubuntu which isn't supported (although props to the Bumblebee people for the progress they've made) it's hit-and-miss if even that will work. If the rest of the W520 wasn't such an awesome laptop, I'd be really quite upset. As it is, I just live with it and boot into Windows if I want to use a projector.
- _delirium 13y agoAny idea why it needs a reboot? Some MacBook Pro models have that kind of switching (integrated Intel + discrete nVidia) but don't need a reboot to switch between them. Is it some architectural thing, an issue with the nVidia drivers, an issue with Windows, ...?
- thristian 13y agoModern Mac OS X is a bit smarter about things, but I believe the original versions of Mac OS X that supported Optimus required you to restart the windowing system when switching GPUs. That required quitting all your apps, logging out, and logging back in, which is effectively a reboot for people who stick to GUI interaction.
- _delirium 13y agoDoing a little searching, it seems it might be tied to the hardware as well, not just the OSX version (not sure if that's a real hardware limitation or a driver issue though). The dual-GPU MacBook Pros from mid-2010 onwards have "automatic graphics switching" that does it on the fly: http://support.apple.com/kb/HT4110 http://support.apple.com/kb/HT4110 You're right that the 2008/09 models required logging out/in to switch manually; I hadn't realized that: http://support.apple.com/kb/HT3207 http://support.apple.com/kb/HT3207

- marcus_holmes 13y agobizarre timing, I've just spent the entire day moving my laptop to Debian XFCE, and the vast majority of that time was spent trying to get the bloody Nvidia card to work, which it won't because of Optimus, so that I can play with WebGl. Then I find out that it'll never work because any hybrid rig is excluded from WebGl (presumably because of Optimus randomly deciding that browsers don't need GPUs). And of course I can't disable the Intel graphics chipset from the BIOS. sigh
- thristian 13y agoMy understanding is that the nVidia GPU doesn't actually have access to the screen; when you turn on Optimus mode, the nVidia GPU draws its output into a texture or frame-buffer on the Intel GPU, which actually pushes the pixels out to the display. So if you could disable the Intel GPU from the BIOS, you'd wind up with no video output at all.
- xamlhacker 13y agoFor Linux, did you try the Bumblebee project? I had some success with it. Once bumblebee is setup, if you want to use the Nvidia GPU for some program, you just launch it as follows: "optirun /path/to/your/program".
- zanny 13y agoAlternatively, if your gpu is supported by Nouveau reclocking, PRIME is the best hybrid graphics experience you are going to get. I just edit .desktop files of programs I want to run on discrete graphics to include DRI_PRIME=1 and almost all work flawlessly if your window manager supports xrender and you have a compositor running. It just means your gpu performance suffers using the community driver.
- marcus_holmes 13y agoyeah, but it's no longer current/supported as far as I can tell.. the actual project appears to be dead and I can't find it on the backports at all. Shame, because it looked promising for a while. I'm a bit amazed that Nvidia isn't supporting this more, given y'know, SteamOS just around the corner.
- dangrossman 13y agoThere's no good story about switchable graphics still, even after all these years. My 2010 HP Envy had both an integrated GPU and discrete ATI Radeon, and a custom driver from HP/ATI that gave you a tray icon to switch between them. Worked great in 2010, but the fact that a custom driver was required meant in the following years I had trouble with newer games, and the computer barely functioned at all in Windows 8, often booting to a black screen even in safe mode. As for the "who buys an i7 for battery?" -- well, I do. You don't have to choose between battery and performance with Haswell CPUs. I finally gave up on discrete graphics to get an ASUS UX301LA -- an i7-4558u that gives me 8 hours of battery life in an ultra-thin ultrabook form factor, yet the Intel Iris* GPU is faster than the discrete Radeon of my 2010 laptop. Games like Starcraft/Diablo that don't push boundaries run perfectly at the native 2560x1440. If Intel's integrated GPUs keep improving as much as they did this generation over the last, the days of discrete mobile GPUs are numbered.
- 3825 13y agoIt looks like Google fails to correctly decipher Intel Isis (probably because it is still new). If you were searching Intel Isis, OP probably meant Intel Iris[0]. Intel Iris and Intel Iris Pro were introduced with Haswell processors. > Intel Iris Graphics and Intel Iris Pro Graphics are new brands for Intel's high-end integrated graphics introduced with some variants of its Haswell processors. They utilize the same basic blocks as the HD series, but have a higher maximum frequency, and additional eDRAM cache for the "Pro" series.

- ansible 13y agoThe Iris Pro with eDRAM (Crystalwell?) is an interesting offer from Intel. If I was in the market for a new laptop this year, I'd be keeping an eye out for those Haswell refresh or maybe a Broadwell based laptops, similar to the newest Macbook Pro.

- trurl42 13y agoHaving bought a laptop with a ATI Intel hybrid graphics solution in 2011: - I'm still stuck on the driver version from 2011, can't install a newer one. - Only works for DirectX, with OpenGL you can only use the Intel graphics.
- nly 13y agoThis is actually one nice thing about NVIDIA.. there are notebook drivers on their website that work with most of their mobile GPUs. I'm pretty sure you can get upstream AMD drivers working with ATI cards though... it probably requires some ini tweaks or something.
- jblow 13y agoI have owned 4 or 5 Optimus laptops and have never gotten a practical benefit from Optimus. At best I leave it switched to the fast GPU permanently. At worst, something goes wrong. The state of Windows laptops these days is really kind of embarrassing. Nobody knows how to build something of quality. Everything appears to be driven by bullet-point features with a goal of providing USPs, but nobody really cares if the features work or if the overall product is good. This extends to everything (keyboard and trackpad design, screen, preloaded software, function key mappings, etc). I buy 2 or 3 laptops a year; traditionally the case has been that most laptops were kind of bad but if you looked hard you could find something good. Now it has gotten to the point that the something good no longer seems to exist at all. I dread the idea of buying a new laptop now. This can't be the high-level result that these OEMs really want.
- aram 13y agoI thought the situation improved a bit with the appearance of ultrabooks; however I haven't had a chance to test one of them thoroughly. Did they bring higher quality or they are just thinner with slightly better specs/battery?
- dangrossman 13y agoIf you're willing to spend at least $1500, you can find some ultrabooks with decent build quality from Lenovo/Asus/Samsung/Sony. None of them get every detail right; keyboard layout is always a challenge, and I had to remap home/end/pageup/pagedown to make this one usable for programming. Vendor-specific apps for the trackpad and power management suck and they'll be installed on even the most expensive systems. One problem seems to be that we're such a tiny addressable market at this point that the best PCs never make it into stores. You won't find any Haswell i7's in ultrabooks at Best Buy / Staples / etc; just the lower-end i5 and HD5000 graphics clones each brand made. This one was only available from Amazon, which seems to pick up something like 30 units a month from ASUS. Samsung makes a very nice configuration of their Ativ Book 9 Plus that's both beautiful and powerful, but when I checked my local stores they only stocked cheaper models.

- hengheng 13y agoWhile the front-end to Optimus may be less than optimal, it's quite well done internally. I came across it when I hooked an external GPU to my laptop. This is possible via ExpressCard with a passive (mechanical) adapter, and it even hot-plugs in Windows and installs the correct driver out of the box. It does require a reboot the first time, but other than that it's smooth. What Optimus does is texture compression before textures are sent over the single PCI express 2.0 lane to the GPU. It can also enable my external GPU to render back into the internal notebook display. I'm baffled by how easy this is to set up and how flawlessly it works, and honestly I am surprised that none of the commercial solutions has ever succeeded. ExpressCard even supports a USB 2.0 port, so I can plug my keyboard and mouse to the adapter, which then effectively works as a docking station (except for power).
- bitL 13y agoI have an ASUS Zenbook Prime UX32VD-R4002V with NVidia GT620m and Optimus works flawlessly, both in Windows 7 and Linux Mint. Most games and demanding software switch to NVidia, HD4000 is used only for bare desktop and browsing. There are other issues with this ultrabook but Optimus is not one of them. Both DirectX and OpenGL work on both chips, output via HDMI works from both of them and I can even use CUDA in After Effects CS6 by adding 620m to the list of supported cards. The OP's experience is probably constrained to his particular model.
- danmaz74 13y agoI have the same notebook, and my only complaint is that quite often the notebook monitor doesn't switch on until I connect or disconnect an external HDMI monitor. A pity.
- bitL 13y agoI don't have that problem - it works flawlessly all the time. I am using Amazon basics HDMI cable connected via HDMI switcher to the external display (with the desktop, Chromecast and Tronsmart Android stick occupying 3 more HDMI inputs). Try perhaps another HDMI cable?
- danmaz74 13y agoI think that's something with my machine, but never wanted to wait for a repair. BTW the HDMI is not a problem: The laptop monitor is often not working when I boot the pc up without any external monitor. But then, attaching one, it will start working.
- gdrulia 13y agoIt baffles me for ages now, how do PC keep such high selling levels, when even now, if you buy a laptop, very likely you will have a crap which will require some technician attention before you will be able to use it properly. Not to speak about crappy apps that comes already installed. Last time I experienced problems was with Samsung Chronos 7 laptop, that my girlfriend bought last Spring. Weird RAM usage issues, Windows issues, etc. In the end, it really wasn't the experience that average laptop buyer is after and no doubt that some then looking into alternatives (tablets) eagerly.
- Friedduck 13y agoMy hard-won lesson is to thoroughly review any newly bought laptop performance during the return period and take it back at any hint of trouble, particularly anything that may require a driver update.
- jokoon 13y agoLaptops are not designed for gaming nor performance. I wish some manufacturer would make a very thick, powerful laptop, as thick as those first mac laptops, without battery, but a good CPU and GPU, and a fan big enough to properly cool all that. If the laptop is thick it will be much easy to cool it. The current iMacs for example are quite thick, and such a machine would be transportable enough as a laptop as a 17 or 15 inch screen. You would not need a battery anyway, there are plugs everywhere, even in trains. If you plan to work on a laptop, it's for at least an hour, if you have an hour I think you will find time to find a plug easily. If you really need mobility a smartphone or tablet will be more useful than a laptop.
- keyme 13y agoYou mean like this? https://www.asus.com/Notebooks_Ultrabooks/ASUS_ROG_G750JH https://www.asus.com/Notebooks_Ultrabooks/ASUS_ROG_G750JH
- coin 13y agoWebpage is barely viewable on an iPad. I hope their laptop is better than their website.
- hrkristian 13y agoThose exist. It was interesting seeing him name ASUS, as I own an ASUS G55VW which is a 2012 Republic of Gamers series laptop. The laptop is a quite bulky 15-incher, my friends make fun of it asking if it has hover capabilities, but for a good reason: it has a fantastic cooling system. The design is also amazing, keyboard is perfect, trackpad works great, and best of all, it lacks Nvidia Optimus. I bought it for that very reason, back in 2012 when I bought it Optimus support on Linux was horrible. It's better now, but the technology itself is kind of pointless, as Mr. Gomes explains. People have become some hung up in weight and size wrt. laptops, but we have tablets now if we want something light, in fact, I'm using only my Nexus 5 and my laptop to cover all the tasks I ever go about day-to-day and they do their respective tasks wonderfully well. Buy a hulk, buy something of quality, no-one types on the fly, anyone can transport a few kilos worth of hardware when it's so. damn. practical/versatile.
- frou_dh 13y agoI'm actually fairly happy that my 2-GPU 2009 MBP is primitive in this regard, in that it has no auto-switching at all. Switching GPUs is manual press of a radio button that then prompts a logout (there's also a 3rd party menubar utility that lets you do it without the logout).
- masklinn 13y agoConsidering how well GPU-switching works in OSX, why would you be happy that your machine is too old to support it? (and gfxCardStatus will also allow forcing on later machines)
- frou_dh 13y agoBecause I only occasionally need the high-perf GPU and can sidestep thoughts about how well or not-well auto-switching is working on any given day.
- Ma8ee 13y ago"this is the time I wish I could afford a MacBook". If you work in any IT related job in the US you probably would end up on the plus if you just spent the time you just used to try to make the crap you bought to work properly working a few extra on your normal job and then bought a MacBook. I can seriously not afford to not buy a MacBook.
- speeder 13y agoI am in Brazil, I earn about 20k USD year as mobile programmer (and for Brazil this is VERY, VERY, VERY high income) Also in Brazil everything (and I DO mean EVERYTHING) is more expensive, Macs usually have a 100% markup compared to US, most of the extra price in taxes. (Brazil has some crazy taxes, for example Videogames have 72% of their final price being taxes, Cachaça, Brazil national cultural beverage, 82% of the final price is taxes...). Here one of the easiest way to get "easy money" is smuggle stuff (usually electronics and clothes, but last year the government had to arrest massive amounts of tomato smugglers), for example you can go to US, buy a bunch of MacBooks, smuggle to Brazil, and charge 50% more of what you paid for them in US, and profit that 50%, and for a Brazillian this still is cheaper than buying a legal one here (that has 100% markup, as I mentioned earlier).
- Ma8ee 13y agoI feel your pain. I was careful to be specific about what I said was valid in the US, both because of very different costs and very different salaries in other parts of the world.
- spobo 13y agoIf you plan on gaming, DON'T buy a laptop. This is solid advice. Gaming on laptops is a bad experience in general. Just buy a decent laptop with great battery life & mobility properties and a PS3/4 or a cheap gaming PC for gaming.
- zanny 13y agoSteambox came a callin'. Remember that stream tech Valve wants to use works both ways, so you could stream games from your mid range Steambox to your notebook.
- mercer 13y agoIt is solid advice. Unless you don't need to play the latest games. I bought a MacBook Air a few months ago and found out that a lot of blockbuster games from a few years ago perform pretty well, as do a lot of the indie games (from Steam, for example). I even bought a wired xbox360 controller for some of these games (Mark of the Ninja, for one). But then I haven't really done much gaming in the past few years, so there are/were tons of (older) games I haven't played yet (BioShock, Portal 2, Mark of the Ninja, Borderlands 2 etc.). And I also don't mind turning down some of the graphic effects. Still, it's possible...
- virtualwhys 13y agoI've had both mac and pc laptops. These days I don't touch anything but Dell Precision workstations, absolute beastly machines (i7, 2X SSD with option for a 3rd, and 32GB RAM) with dual fans. Runs Linux like a boss, zero issues. The Nvidia GPU, however, that is a serious PITA -- in order to keep the chip from going into max power mode 24/7 with a multi-head setup, I had to resort to flashing the VBIOS. Risky, but necessary if you want peace & quiet.
- blueblob 13y agoYou want to mine bitcoins with a laptop? Why? The laptop will wear out faster, you would get better performance per cost with a different option, many other reasons not to as well. Also with fairness to the nVidia Optimus, AMD has "Dynamic Switchable Graphics" that is quite similar. The state of linux support for my laptop with the AMD equivalent is not the greatest either. In linux, there are quite a few projects providing some form of support to this, (note the Nvidia Optimus section on the archlinux wiki for Hybrid Graphics[1]) so stating it doesn't work at all on mac/linux is fairly untrue. [1] https://wiki.archlinux.org/index.php/hybrid_graphics#Nvidia_Optimus https://wiki.archlinux.org/index.php/hybrid_graphics#Nvidia_...
- supermatt 13y agoI appreciate the review, but instead of suffering why not just return it? Your describe the item as not fit for purpose, which is, in the eu at least, a valid reason for return.
- knappador 13y agoI had to check the article date twice. Seems old and kind of just a rant. Just be glad you're not still messing with XFree86 modeline settings or whatever. Asus makes high quality products at a good price. Their Zenbook line might have something you are looking for. As for Optimus, I used a bumblebee alternative on one that just required a special parent process (optirun or something). The light sensor would give off random keykodes due to a kernel bug that was fixed in master. I put a sticker over the light sensor until this was done. Other than that, everything about the hardware was pretty standard configuration job every step of the way. The latest nvidida drivers are said to support Optimus on Linux. Quite frankly, I enjoyed the battery life immensely when just using the Intel graphics for running Compiz at 60fps no problem.
- jnamaya 13y agoI bought a lenovo w520 because if its performance. It has become hell to run linux comfortably on this laptop. I have set it to "discreet" mode in the BIOS and that seems to ease some of the problems...but yeah, if you want performance and a good working laptop, especially linux, stay away from these dual-card video laptops.
- mbailey 13y agoOptimus effectively thwarted my genuine desire for going back to a Linux workstation at work. Traded it in for a Mac after three weeks. Oh well, I'd rather get work done than dick around with X I guess.
