for some magic reason you are very right i did your settings and they work
with 5800x and 7800xt i have constant 125-144 fps no stutters on 1440p and usage of gpu about 80-90%
so to sum up from the posts above
CAR REFLECTIONS Ultra Low,
MIRROS Ultra Low or OFF
CROWDS to Low or Ultra Low
SHADOWS from Ultra Low or upper where you feel comfortable
and as said above "framerate and GPU utilization go way higher and I gain a TON on smoothness"
also the game doesnt like native resolution but upscallers do the job
I have 12900K and was limited to about 72 fps @5120x1440. So i exchanged it with RTX 4090 and hope to get a 120fps native.
Sadly enough i'm still limited at 72fps and an average of 50-60% GPU load. Quality settings hardly make a difference in fps, DLS on/of is also doing nothing
Check the settings of the above post and everything else to ultra
I had the same problem due to multiple usb input devices (wheelbase + pedal). After i disconnected the pedals the FPS increased by 50%.
