@dxgl_info Well...if that were true, they started this plot in like 2004. Tweeted 19 Aug 18 in reply to William via Twitter Web Client

@Nax_Dev You're right, you _shouldn't_ gain _this much_, but Apple's GL is...not comparable to other platforms. Tweeted 18 Aug 18 in reply to Nax via Twitter Web Client

@cybik SDL has src/test/testvulkan.c Tweeted 16 Aug 18 in reply to Renaud 和彦 Lepage via Tweetbot for iΟS

@morgancox_uk It was about what I expected it to be. I also thought that The Lion King (currently the third longest running show in Broadway history) would be a flop. 🤷‍♀️ Tweeted 15 Aug 18 in reply to Morgan Cox via Tweetbot for iΟS

@cybik It’s hard to do safely and portably. Vulkan, DX12, and Metal all support (and encourage!) threading. Tweeted 15 Aug 18 in reply to Renaud 和彦 Lepage via Tweetbot for iΟS

Olive is taking in her first Broadway show...rather, her first show _on_ Broadway. Letting it go at Frozen. :) pic.twitter.com/Dth0ZhguuT

@leovarmak @natbro Sounds like an sRGB conversion issue. Tweeted 15 Aug 18 in reply to Karthik Varma via Tweetbot for iΟS

@wolfgangengel Maybe, but not in any meaningful way. Tweeted 13 Aug 18 in reply to Wolfgang Engel via Tweetbot for iΟS

@mcclure111 This is a legitimate concern. Tweeted 13 Aug 18 in reply to mcc via Tweetbot for iΟS

@ophidianab To be clear, there is no reason that OpenGL should perform this poorly other than Apple’s OpenGL implementation is bad. It could be fixed. The same GL code is fine on Linux and Windows. But it does make it clear that on the Mac, one should skip GL for other available options. Tweeted 13 Aug 18 in reply to Aaron Clark via Tweetbot for iΟS

@mcclure111 This is an ongoing emotional struggle for me: Vulkan is a better citizen of the world, but Metal is SO MUCH NICER to work with. :( Tweeted 13 Aug 18 in reply to mcc via Tweetbot for iΟS

@vectorpoem I have to consolidate this with the idea that OpenGL itself would have died in the early 2000s if not for Apple. But honestly? If MoltenVK gets you quality Vulkan on macOS, that’s better than Apple providing a closed-source implementation. Tweeted 13 Aug 18 in reply to JP via Tweetbot for iΟS

@staticchar We’re at the point where, Apple or not, it’s time to move to nextgen APIs, so this isn’t unreasonable. Tweeted 13 Aug 18 in reply to Elons Husk via Tweetbot for iΟS

@minimalist_unix First: that’s a non-trivial effort. Second: for me (who has had Unreal source code for almost two decades), it would be extremely legally questionable. Tweeted 13 Aug 18 in reply to I updated my privacy policy via Tweetbot for iΟS

@hoserama99 @noxegon Yeah, the only reason I’d mess with that is if they suddenly lock you out of a new arch (ARM MacBooks or whatever) or lock you out of the App Store. Way too early to spend effort for that specific case right now. Tweeted 13 Aug 18 in reply to Brad Oliver via Tweetbot for iΟS

@mcclure111 I think they have a demo that adds a watermark to the framebuffer, just so you can see if it’s worth the money. Tweeted 13 Aug 18 in reply to mcc via Tweetbot for iΟS

@mcclure111 In fact, it would be interesting to use our GL code with MoltenGL (same idea, provides GLES instead of Vulkan) and see if performance jumps. Tweeted 13 Aug 18 in reply to mcc via Tweetbot for iΟS

@mcclure111 My guess is it will speed up. Apple’s GL was always inefficient, so replacing it with literally any other implementation would probably improve it. Tweeted 13 Aug 18 in reply to mcc via Tweetbot for iΟS

@noxegon @hoserama99 I think you’ll still be able to hit 60fps in that scenario. :) Tweeted 13 Aug 18 in reply to Richard Bannister via Tweetbot for iΟS
