Low GPU usage in Urzikstan only

So, I have this new build. Ryzen 7 9800x3d, RTX 5080 amp extreme infinity, 32gb ddr5 ram at 6000mhz, 1000w psu. Multiplayer and Resurgence are fine.. 90%+ gpu usage. When I get to urzikstan it's around 60% gpu usage and I don't understand why. I still get around 200+ avg fps but it's annoying knowing I could get more and I don't understand why it doesn't use it all. I know the game is trash and it's badly optimized but still I see people with the same build and they get 97%+ usage at all times in Urzikstan. I have everything set on max performance, I played with a lot of settings etc nothing changes it. What can be the problem ? I tried about everything and nothing seems to work. I'm on steam and I heard some people saying the game works better on Battlenet. (I'm downloading it right now just to try and see if there's any difference and I'll come back with an update, but I doubt that's the problem) Also I tried all the games I have installed, about 10. No other game has low gpu usage so at this point I feel like I will give up tbh. It must be the game awfully optimized. I thought I would ask and if anyone has/had the same problem I would appreciate some feedback that could help me and maybe others.

UPDATE ON THIS: Looks like playing on battlenet did the trick. I get around 100 more fps compared to steam.
