RX 6900XT Valheim Vulkan Crash

Hey Folks,

I could play Vlaheim on my PC with DirectX. But the performence often drops below 20FPS (Max Settings on Samsung CRG90@5120x1440) if I went to our big city.

the GPU doesn´'t hit the 95%-LOAD mark.

So I tried to start "Valheim with Vulkan" but every time I start the game. I´'ll hit the 2000FPS mark. But in the Moment the main menue should appear the PC powers Off.......
And I could´'nt start again. the PC wouldn't do anything... So I pull the power plug and wait 2mins. After that he get back on, but I get the Failure every time the same way. 
The event-log doe´n't store any Problem.

I Hope someone could Help me.
Many Many Thanks!

My System:
MSI X470 Gaming Pro
16GB G.Skill Flare X (CL14
AMD Ryzen 2700X
Corsair RM750i

Does it still crash when you enable the frame limiter in the driver?

What PSU are you using? Reminds me on my Vega 64 with a similar system and an 650 W be quiet Dark Power P11.


Game crashes for me to in Vulkan only fix is adding this to the boot.config in the valheim_Data folder


I just wish fps was higher i am seeing it tank down to like 40 at times which is insanely low
