If I remember correctly I got something like 4K-8K fails (total is 40K tests) when I broke the GL1 restore dispatch function. So it is around 10%-20%. Maybe it was only the test below 3.1. I was afraid that various modern extension could still be tested with some GL1 drawing. On 2/13/17, Marek

Hum, I need to check it. I think I disabled EGL because I didn't have latest waffle on my Debian (and Nvidia didn't support fully EGL back then). However, I forgot to say that a fair number of piglit tests are based on GL1 direct call. (typically to draw a rectangle without a VBO). All those

Re: [Mesa-dev] Time to merge threaded GL dispatch? (aka glthread)

Just to clarify my email, I wasn't saying shader-cache should land before this, or that we should prioritize one over the other. I was simply venting frustration that I had to keep it rebased out of tree and keep it passing piglit when it seems I didn't need too. This is nothing against this

Re: [Mesa-dev] Time to merge threaded GL dispatch? (aka glthread)

Hello, I ran piglit (glthread false vs true) on the Marek branch and Nouveau driver. Of course we can still debate, if piglit is good enough to detect multi threading issue. I spot a small typo that generate ~400 fails (*mat2x4* uniform got 6 scalar instead of 8). piglit status with the typo

Wait what? You just side stepped everything I just said with regards to prioritizing the volume of work that went into shader caching over gl dispatch with essentially `gl dispatch is really great and our users friend it super useful now`. That's fine, I'm not ageist it, maybe you misinterpreted

FYI. Civilization VI is another game that works with and benefits from glthread. The game was just released. Even Nvidia is CPU-bound on highest details and can't reach 45 fps with full hd. People wanting to play Civ VI with decent frame rate will want glthread. I don't think they care too much
