Hey all, want to hear some ideas of what might be the issue/bottleneck

I just got an asus prime 9070 gpu and have a 5700x as a cpu paired with 18CL ddr4 3200 MT/s ram

I have PBO turned on so my cpu can even reach max clocks for higher and even go +100mhz

I am testing “Mafia the old country” which is an UE5 game and it seems that no matter my graphics settings, i always fail getting consistent 60 when i start the game and go outside of the cave

Last setup i tested is high settings with fsr “quality” upscaling in 1440p and getting like 50 fps, never reach 60 fps

My gpu is 75% utilized based on mangohub and lact

My cpu cores are all under 60-70% max

Im on proton experimental and use NTSync.

Is it possible the game have big ram access that might cause the bottleneck or something?

Or it might just be an issue with the game?

I just believe that with this hardware and using upscaling it should be consistently over 60fps
