> Suppose during my regular game development everyday life I've installed Photoshop recently and I want a look at a screenshot of the game - someone reported a problem or something. > So I double-click on the thing ... one ... two ... three ... four ... five ... six ... it's about seven seconds before I can actually see the image. [...] > So that's really slow and I'm going to talk about that for a bit, but there's an element of severe irony to this which is that as soon as I double click this thing within one second it draws an image and it's a pretty high resolution interesting image. It's just not the image that I care about. > So obviously it's not hard to start a process and draw an image on the screen in much less than seven seconds. They just don't manage that. > Now. I gave a speech a year ago that started this same way. That was 2016. It's now 2017 and of course a new version of Photoshop has come out and of course what will align directly with my point in the next few slides: they've made it worse. And the great way in which they've made it worse is: say there's some operation that you want to do maybe once in a while like create a new image... So I'm going to go to file, new ... Urghh. And that menu takes - it probably takes about a second to come up. > And you might think "Oh, well, you know it was just all these assets were cold or something.. Maybe they come off the hard drive. It'll be faster next time." And it's like: "Well, let's test that out. Nope." Like every time. I'll use the keyboard shortcuts. File. New. Nyeaarghh. [...] > Imagine if the people who programmed this were trying to make VR games. Everybody would be vomiting everywhere all the time. > Well what machine am I running this on? It's actually a pretty fast machine, it's a Razer Blade laptop with a pretty high-end i7 in it, and you can talk about how fast the CPU is or the GPU is and some arbitrary measurement and I'm going to discuss CPU speeds here and I want to say in advance that none of what I'm about to say is meant to be precise or precise measurements. I'm making a general point. > And the general point is that the CPU of this thing would have been approximately the fastest computer in the world when I was in college. Or the GPU would have been the fastest computer in the world in the year 2000 or thereabouts. > Now you might say "That's a really long time ago. This is ancient Stone Age." Well. Photoshop was released in 1990 before either of those dates. And Photoshop 6, which I used heavily during my earlier days in game development is from the year 2000. And this is what it looks like. This is a screenshot of Photoshop 6. It's got all the same UI that Photoshop has today. It's got all these same control widgets and it's got our layers and channels and all that stuff. Today the UI is a different colour but apart from that it's essentially the same program. > Now I don't doubt that it has many more features. But you have to ask how many more features are there and what level of slowdown does that justify? - Jonathan Blow, Reboot Develop 2017: https://www.youtube.com/watch?v=De0Am_QcZiQ&t=155 https://www.youtube.com/watch?v=De0Am_QcZiQ&t=155
