Over 70 hours into this game but find myself constantly playing with the graphics settings and I still haven't figured out what's going on. I have an AMD 7900X CPU, GPU is a 3090 and 32GB DDR5 RAM. With everything maxed out I'm getting high 40's but occasional drops into low 30's, which causes stuttering. If I enable DLSS then it doesn't really help FPS, it just lowers GPU usage. That makes sense in my head as it will be rendering at lower resolutions and therefore it's logical that it becomes CPU bottlenecked. What doesn't make sense is I tried leaving DLSS and any other form of upscaling off (i.e. no DLSS/FSR/XESS) and lowering the graphics settings and it still doesn't improve FPS... it just lowers GPU usage.
I definitley don't have any form of FPS cap and every other game runs fine, so I'm pretty confident it's not my system. All drivers and my BIOS is up to date... anyone got any idea what's going on, is this game CPU bottlenecked at 1440P?
