Can you enable the full performance overlay of the game? I think it's pretty likely that the game runs on the integrated Vega GPU instead of the 6700XT when using vulkan? Do you set DRI_PRIME somewhere?

Oh ok I'll set it and take a look also no I haven't set DRI_PRIME anywhere

Hmm it seems to be using my RX 6700XT
Weird. I have the same GPU and the game runs at the 200 fps cap at max settings on vulkan.

Hmm that's odd and what CPU and desktop do you have?
Hello @coreybruce, this issue should also be mentioned to your video driver vendor if it hasn't been already.

Like the distro or who makes the driver because I'm using the open source mesa driver
I have similar config to @coreybruce and on latest proton and there are frequently fps fdrop from 200fps to 38-45. When i run game with proton ge issue disappear.

Use OpenGL 4.5, the performance is fine when you use that
I can't repro the issue here, Mesa 23.1.1, Proton 8.0-2.

Seems to be fixed now

Performance under vulkan is significantly lower than it is with OpenGL 4.5
This is the settings I use for both Vulkan and OpenGL
