Running 40 or 50 FPS on RTX 20 series cards with still plenty of GPU power could

It's an optimisation issue not a DRM issue, AMD cards are running the game just fine, but it seems a lot of Nvidia cards are having this low utilisation bug.

Best thing we can do is wait until Codemasters releases a performance optimisation patch or Nvidia to release a driver that addresses the issue.

Here's a shot from Bang4Bucks video where it shows a 6900XT fully utilising the GPU vs an RTX 3090 only using 91%, this results in the AMD card getting around 15 to 20fps more at 4K. 

The second shot is from my own video showing my GTX 980 only getting 90% utilisation.

Okay now I've just all faith in everything, this is Grid (2019) showing the exact same problem.  So game is literally a copy/paste of the of the previous game, also this indicates a driver problem because Grid Autosport and F1 2021 don't have the same issue.  Definitely sucks because Legends is a much more complete game compared to the dumpster fire from 2019 :P

I had the same issue with the game ,so I started to play around with the settings and turns out that the problem was the crowds setting , after turning it off and restarting the game I don't have this issue anymore. Will keep an eye on the things (as of writing this May 15 2024)

Playing at ultra high preset with crowds off at 1440p

PC specs:
i5-100600KF
RTX 3060 Ti
32 GB RAM 2666 mhz

Edit 1: Had msi afterburner with rivertuner stats running in the background for any heating issues and starting playing GL and had low FPS , after closing the game and msi after burner , didn't have low fps anymore.
