The internet is your friend.

Vulkan def, for performance wise. However you may experience freeze/crash on certain levels on a specific location. Example, Moscow "Resurrection" (4th stage), you will always freeze when you release and escape the nerve gas . Its annoying and they havent fixed it since base game.

I run MUCH better with Vulkan than DX11.

[Geist]

Can just try running the benchmark with both and use whatever works best for you.

They're pretty much the same.
IF ever there are differences, they're negligible at best.

I have a 1070 in 1st person and get the following in game benchmarks @ 2K settings on highest:
Vulkan FPS 109 GPU 98%
DX11 FPS 69 GPU 59%

Odd DX11 sucks so bad.

0 difference then.

[♂TheBlasterMaster™✞]

There are side by side videos showing the difference. They are not noticeably different though.

DX11 is for compatibility, but if you want optimization, Vulkan. If you have a potato for a machine, use FSR to help with getting better framerates.

Directx 11 ran better for me, am I the only one?

When you calculate both up to 100% GPU, DX11 is actually faster than Vulkan

69 FPS at 59% GPU equals to 116FPS at 100% GPU
109 FPS at 98% GPU equals to 111FPS at 100% GPU

Could it be that you've enable VSync or a FPS Lock (either ingame or on driver level) while using DX11? Vulkan consumes all your GPU resources while DX11 does not which brings up this assumption.

No VSync or FPS lock. Settings were exactly the same.

Could also have other reasons why the GPU will only be utilized up to 60%. On the other hand, 60% reduces power consumption and heat production significantly (a reason why I lock my 3090 to a certain FPS). But in comparison with equal GPU consumption, DX11 does definitely not perform worse than Vulkan. Vulkan's benefit is first and foremost the FidelityFX on which you can improve your FPS by downscaling the calculated picture and upscaling it afterwards (the process is more complex but that should be enough explanation for now ;) )

In my case vulkan utilizes gpu a little bit more, I get far more fps with vulkan than with dx11 on a 3060ti.

You should use vulkan if you don't find any problems. If you have bugs, game closes, stutter....stick to dx11
