RADV Vulkan Driver Can Now Correctly Render Talos Principle

[airlied]

actually I just pushed a fix to support srgb and unorm to the branch, it works with talos and dota2 now.

I don't fully understand why the development of this is so fast (compared to how OpenGL specs are so slow)

opengl specs are much larger and radv reuses much of already written code for opengl or for other drivers

Mostly low level code like Gallium. Probably same functions - different names.

Would it be possible to run these benchmarks with the ultra setting, or is radv not yet able to do that?

Looking at haagch video (and ignoring bright picture), there are some artifacts so still misrender on ultra

No need to ignore the bright picture now: https://www.youtube.com/watch?v=GltTu_BA7rc

Yes, ultra gpu speed is still buggy. The rest looks okay. Frame times on high are pretty bad. :/

This is awesome. Seems like I'll be able to use both GPUs to render games sooner than expected!

I see that some people can run Talos with a 7970...

Do the game work or just the benchmark? I ask because I tried and well, the menu work fine in Vulkan but it crash when I try to start to game to play. I did not try the bench mode as I have about 30% chance of getting a system wide crash.

Most vulkan demo and the totally useless vulkan triangle I programmed work fine.

Edit??

The problem I got seam to come from amdgpu. Talos is still crashy on OpenGL. It's playable but exiting Menus sometime will kill X.

Will go look to fix that.

My result with windows, yes windows opengl is slower,
full hd, high\med\high\none (most high and stable settings for me)

OpenGL	72	57
Vulkan	111	135

Thanks for the response.
Yup, no point in looking at performance too closely until it renders everything properly.
