In the meantime, are there any other solutions that you and the Google #squad plan to offer? Like...people who will answer a phone call?

You're on HN, so you have access to the Internet. This information isn't hard to find...

Yeah, I'm not sure...why they just let the name get cannabilized. Looks like they moved over to "Visual Studio Graphics Debugger".

Well, what are you trying to do (from a beginner's perspective)? Are you trying to quickly understand how to draw a triangle to a screen with a texture? I would say...write a quick software rasterizer. Are you trying to understand how

Actually, that feeling you had of not believing it because it seemed so improbable is a fairly common reaction (in my experience as a PoC). It was an "aha!" moment for me to realize that not everyone has had those experiences, an

That 500 GB/s is the bandwidth between the NV shader cores and the GPU RAM, not between the shader cores and CPU accessible system RAM. You don't want to be transferring between the two pools that often, as those buses are much s

1. They have no say in the API so NV would just steer the API in ways to make sure it would be suboptimal on AMD hardware. 2. It's not just the API. It's the entire SDK that has NV specific hooks that AMD can't tap into

Actually...that might be changing on GCN. Check out Graham Wihlidal's presentation from this past GDC. Advocates some benefits of de-interleaved VBs http://www.wihlidal.ca/Presentations/GDC_2016_Compute.pdf

Well, sheds light on their Compute Unit architecture.

Besides the good reasons brought up by other posters, game devs tend to be very secretive of their shader code, so they like the bytecode as an obfuscation layer.

I'd actually argue that not that much changes, except APUs mean you don't have to worry about different memory pools, and moving stuff across the bus. That's a whole other problem, as far as streaming data management. If we

by robbies 10y ago
Noooo, please don't do that. That is not the intention of that API at all! The API was built so that the cost of compilation by the driver would only be done once (likely at install, or at driver update time). So the idea is that whe

Not OP, but both Uber and Lyft tie bonuses to weekly/monthly acceptance rate and rides completed. I can't recall numbers, and they have been tricky to find on my phone. But I too can anecdotally confirm that Lyft drivers seem to

So the 60Hz reprojected to 120 Hz is an option, but not the only one. Games can run at native 90 or 120 (perhaps with reprojection additionally)
49.
by robbies 11y ago
Nope. That's one of the options possible, but not the only mode. The device can present at 90 or 120, and the rendering can be done at 60, 90, or 120. Not sure of all the combos possible though (like can you render at 60 and present at

The API itself supports some very cool compute functionality, such as asynchronously scheduled compute jobs. However, this functionality only exists on AMD hardware (to my knowledge). NVIDIA doesn't support it in HW (yet), and I don&

Well, not by 'any' measure (as others have pointed out). Additionally, do you find Metal to be a wholly unique creation? It certainly 'borrows' ideas from other low level mobile GPU APIs out there...

I can't speak to the entirety of their empire, but as far as their rendering command stream: not innovative. Well...maybe 30 years ago. To be fair, that's most of the workstation industry.

We're talking about dash cams here, not body cams. They had TV shows in the 90s based on police chase videos from dash cams. World's Wildest Police Videos first aired in 97, though I suspect there were shows prior to that, the nam

by robbies 11y ago
I think SPIR-V + Vulkan would be the better path to follow, considering that NV doesn't really care that much about OpenCL.

Oh, they have the docs they need. That's essentially what is shared with console devs. The problem is that to get up and running is pretty Herculean with just docs. They need good sample implementations to get kickstarted.

I'm actually amazed that you were able to get an IHV to give you that access. Interestingly, most console developers currently have this sort of access. If they are just targeting consoles (or better, a specific platform), they'r
