Help with stuttering

[L0ngbow]

Hello. Decided to try Battle of Stalingrad today and I'm getting heavy stuttering on my Varjo VR-3. 

Specs of my machine is 4090/5800x3d/64gb/2Tb ram/WD black M.2 on a fresh Windows 10 install. 

I tried to run the game on the lowest setting and its still the same, it's still a stutterfest. I'm on the latest Varjo Base 3.7.2. and the latest nVidia 526.86. 

DCS and Msfs 2020 run great on my system and is at par on what other similar configs run at. I even tried OpenXR and IL2 still stutters. Any ideas on how to solve this?

 

TIA
