Vulkan images not showing.

For some reason my overclock wasn't working in Doom so the results are stock.

1080P Ultra setting :

Opengl = 47fps average

Vulkan = 80 fps

I can't seem to capture a screenshot in steam but the performance is amazing with vulkan.
Fantastic result!

Wow, that is like jumping two GPU gens for you lol

I put a pic of the scene I was playing (opengl) but it is an astounding difference and the gpu doesn't even seem to be overclocked :eek:

.

Steam screenshot feature crashes the pc in Vulkan mode for some reason.
edit: apparently it is a known issue listed in the patch notes.

Vulkan is great, no issues from what I can see so far.

Causes coil whine on my 1070 on the intro screen/load from checkpoint though.

Looks like AMD might see a bigger boost than nvidia with vulcan.

Jesus. I bet that was quite the surprise

I uninstalled this for hard drive space. Gotta download all over again now.

480 gets a massive performance boost.

wow we need more vulcan asap.

Seems to be the way at the moment - some nVidia cards aren't seeing any difference at all which may indicate something isn't working right.

It's called aysnc shaders, they aint got em.

I think there was a hint of light sarcasm.

Anyway. No wonder AMD are losing money if 7950s are pumping out 80fps on max.

In action.

I seem to have a 20fps boost with VulKan

~~Mantle~~ Vulkan with Async Shaders & Shader Intrinsics, plus Frame Flip Optimizations baby!

Do you get much 4k improvement? For me that was the only res that wasn't quite fast enough.

Mauller · 11 Jul 2016 at 19:28

How does the frame delivery feel with vulkan? does the game feel smoother?

That video posted further up shows terrible and consistant frametimes.

BS Dave · 11 Jul 2016 at 19:47

A really quick check sees my 980ti hitting 200fps at 1080 something it didn't do under OpenGL. Bethesda say they're working on async - it'll be cool if they gets something working on nvidia...
