Re: [Old Report] Low GPU Usage and Framerate - WRC - DLSS no change

@Aldo_Zampatti

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%.

Apparently, UE4 just isn't great at multithreaded rendering. This is probably why most people are seeing both low CPU and GPU usage across the board, no matter what hardware they have.

Disabling hyperthreading as a quick test of this on my 4core/8thread CPU increased hardware usage dramatically for me. Didn't actually improve the game performance, but just shows that all cores/threads and the hardware in general available aren't being fully utilized. I went from ~40% CPU usage to ~80% and GPU usage shot up from 50-60% to +90% with the same exact settings as before. Although while my performance didn't seem much better, it might explain why some people with older CPUs and GPUs are claiming the game runs great for them.

Anyway, this is still a real flaw in the latest iteration of UE5 as well, @10:40 this person states UE5 is still only using 2 threads max for rendering, but a UE5 engine update coming sometime in 2024 will have proper multithreaded rendering added. So if Codies ever wants to migrate WRC over to UE5, or build the next WRC release on UE5, they may want to hold off until that junk is in there.

EDIT: Well my missing post is back again. I'll put this down to server issues - removing conspiracy theories. 😃

It work!, but now crash, i have a R7 5800x (oc to 4.95Ghz), rx6700xt (oc too), i will try whitout the oc, this game never crash to me, but i aways have the issue with low fps.
