DOOM's Vulkan update is now live

[WYP]

DOOM's Vulkan update is now live promising some large performance gains over the original OpenGL version of the game.



Read more on DOOM's Vulkan update.

Tried it and can now happily run on ultra and it's really nice and smooth. Quite impressive really

According to the devs if you enable TSSAA you will also use Async Compute but if you use any other type of AA on Vulkan then it is not used.




Interesting that AMD uses Vulkan driver 1.0.17 and Nvidia uses 1.0.8.

Well probably because AMD is more involved/had more time to work with it so got to update it further. Being based off Mantle and all. Probably not a big performance factor though

Does SLI/CF work in Doom with Vulcan?

SLi works for me yeah

To be fair I gave this a go yesterday. Based on Ultra setting OpenGL gives me 65-80 fps and Vulkan gives me 65-85 fps based around the same area of the game. The only difference I could find was frame times actually increased from 12-13ms up to 15-18ms using Vulkan.

I will have a play with the settings at some point and see if I can push anything a little further using Vulkan over OpenGL.

I heard mixed opinions as well. FPS gains in some areas, FPS loss in others. nvidia user though.

 

[AlienALX]

Stupid question.. How are you reading FPS with Vulkan? I have probably the best test system for this API so I need to know how to record it.

This is from another forum but apparently for Nvidia users the Vulkan driver doesn't install properly along with the standard driver, You have to go into the Nvidia directory to install it -

PERFORMANCE FIX FOR NVIDIA USERS: READ READ READ

Sorry about the caps, that was to draw attention.

To get better performance Vulkan has to be installed on your pc first. To do this go into C:\Program Files\NVIDIA Corporation\Installer2\Display.Driver, then install it from there.

After I installed this my GTX 1070 was putting out an average extra 30fps frames, maxed out at 1080p.

I don't know about an actual performance boost as I never looked at the before numbers but I do know now that the Vulkan run time now appears in the install/uninstall window were it didn't before.

Did a DDU on my system and upon restart made sure that both c:/program files/nvidia corporation and c:/program files (x86)/Vulkan RT were uninstalled. Then re-installed 386.69 (on win 10 x64) and both folders were created. Unless you 're talking about something else that I missed.

Yeah I'm talking about something different.

Upon first install of the latest driver many people have noted that the Vulkan driver component has not been installed properly hence you have to go into the install location and install it manually.

Not sure if it's just a weird bug or not but some reported a minor performance gain upon installation -

Yeah I'm talking about something different.

Ok got it. I'll also check on my main rig later, in which I have not installed manually vulcan. On an other note gpu-z reports 99% on first gtx970 and 30% on second running doom/vulcan.

Does your CPU usage on any core increase/decrease when you swap from OGL to VK?

 

[SuB]

interesting, will have to give that fix a go and see if it makes a difference
