amd 6900 xt linux vs windows results with unigine heaven

hi everyone! thought i'd share some benchmarks i did with my 6900 xt with unigine heaven.

if i did my math correctly, about a 16.7% difference in average fps.

Can you test OpenGL on Windows as well? That would be a more accurate comparison in my opinion.

Too bad it doesn't have Vulkan benchmarks yet. I don't think they represent actual situation in games because of that. What you measure is important. Not just the numbers.

It's not really a fair comparisson, DX11 vs Opengl usually ends up like this. Maybe try opengl on both? Or try a Vulkan bench like GravityMark?

Also make sure your CPU governance is set to performance, I think by default it's ondemand or powersave.

By default it's commonly schedutil which isn't a bad option. ondemand isn't a default usually in modern distros.

hi! i have fully converted to linux so i no longer have a windows install, but shortly after i received my 6900 xt i did run heaven in opengl mode on windows and it was absolutely awful. i don't remember the exact score, but it was far worse than the linux opengl result.

though i did test superposition and posted my results in the superposition thread. the gap there between opengl and direct x was only 7%! either way i am very happy so far on linux. the few quirks i worried about have been a nothing burger and the performance has been great
