First time I've ever had low gpu utilization. I tested after the update, and it happens at Kansai going through pits, also starting at the back of the grid in the evening hours. Also, certain parts of Sebring without any car present. I'm running mostly high settings with some on low and was able to hold great framerates no matter the conditions before. I have updated my gpu driver and ran steam integrity check. Steam did find 2 files without any changes related to fps. I'm running a 13600k, 4080, and 32 gigs of ram. I'm about to reset my graphics settings by deleting the documents folder. If anything changes I'll report back. Update! reverted back to older graphics driver brought my fps back up, still not the best but way better than before. Hope this helps someone.
I followed all the steps mentioned above and saw only a slight improvement in FPS. However, when I tried changing some in-game settings from low to medium, the FPS dropped again. At this point, the only viable option for me is to keep using the previous version, which was working perfectly fine.
I’ve observed that using the -fpscap 141 command results in a loss of about 20 FPS. Rather than capping at 141 FPS as intended, my frame rate fluctuates between 119 and 123 FPS. I’m looking for more examples or reports of similar issues caused by the -fpscap command. For comparison, when I use the FPS cap feature in the AMD driver, it holds steady at 141 FPS. So if anyone uses -fpscap it could be worth to check that too. Perhaps an 'issue' on my end, but who knows.
