Phoronix: Updated Portal 2 Vulkan Rendering Code Yielding Great Radeon Results

Valve on Monday rolled out a new Portal 2 build that improves its new Vulkan renderer support. For those interested here are some fresh benchmarks of Portal 2 with OpenGL and Vulkan on the open-source AMD Radeon Linux drivers.

I feel they're doing this for eventually publishing on a small console (e.g. Atari VCS or Intellivision Amico), or on mobile....

I guess they're testing this implementation out before rolling it out to other Source 1 games, like CS:GO.

It would be nice if the loading screens didn't appear so often. I've got this thing running on an m.2 SSD, 5700XT, and Ryzen 3600 and the loading times between scenes is super jarring.

You just described why I've never been able to finish Half Life. One of these days I'll get around to firing up Black Mesa....it's in the backlog.

Maybe they are parsing JSON?

( referenciing the recent GTA V multiplayer load time hack).

Well, I think it's rather a tech demo/experiment. Maybe they'll improve Wine libraries as well to help create a portable environment, or a one-click Linux/Mac port?

BTW, does this run on Macs?

In that Openbenchmarking.org table it lists the processor as

AMD Ryzen 9 5950X 16-Core @ 6.92GHz (16 Cores / 32 Threads)

Pretty hefty overclock that you have there. Where does that number come from?

That's from a bug currently in the kernel, well, the fix will be in the next 5.11 point release. The borked frequencies are exposed via cpufreq/sysfs.

I also see a pretty substantial boost on my R9 390 at 1080p all max, 2xMSAA.

another thing I noticed with the first Vulkan update is that, for me at least, some shadows and ambient lighting effects are broken on GL. easy to miss but obvious when comparing to Vukan screenshots.

the update(s) are not all trouble free, though. at least on my hardware, mouse input becomes buggy and unreliable when not playing at native resolution. native 1080p is perfect 1:1 mouse response as you would expect, but 720p or anything 4:3 stretch fullscreen and mouse movement is selectively ignored below a certain speed.
this only happens with scaling, reduced res is fine when windowed.
