Phoronix: Zink Lands A Simple Fix To Boost Doom Performance By ~10x

For fans of the Doom (2016) video game looking to enjoy the title with the Zink OpenGL-on-Vulkan implementation, a simple fix showed how addressing a simple oversight can boost the performance by a magnitude of 10x...

Run Doom 16 on Vulkan is for losers, winners run it using OpenGL through Vulkan.

Anyway, fantastic boost.

Great.. How does it perform compared to "native" OpenGL then?

Doom 2016 is a nice benchmark, for Native Vulkan vs OpenGL through Vulkan. When it reaches parity (if ever), the code is good. If it goes better than native then I am shocked at the confusion.

Not entirely impossible if besides the translation it also does some sort of optimization. That would however mean that the native Vulkan implementation is also missing such optimization.

Yeah, thus the confusion which I mentioned. Even theoretically it should be impossible, if by going by you are saying is correct. Although, isn't the Vulkan implementation in Doom 2016 older while Zink is actively being developed (with a more modern Vulkan API extensions). Of course just staying positive..

If I had a girlfriend, I would let him bang her!

Women aren't property you can distribute at your leisure.

As for the women, the children, the livestock and everything else in the city, you may take these as plunder for yourselves. And you may use the plunder [Yahweh] your God gives you from your enemies. (Deuteronomy 20:14 NIV)

Of course not, I know that, but I meant like if she was willing and interested in engaging in such an act, then I wouldn't be upset about it. I would be okay with it.

Too bad this is not getting into Mesa 23!

It is a trivial patch, would be very easy to add to a build if you really want it before it is in a mesa release.


I find it crazy that just a flag was causing a software fall back, destroying performance.
