After 20 minutes of playing my game is using 100% of gpu and the game starts having 5 fps. I have fps capped to 60 in RTSS. 6. Exit Task Manager, click OK in the System Configuration window, and restart your PC. When you're experiencing high CPU usage but low GPU usage, it is a good idea to get rid of unused background apps. They can free up a lot of CPU memory, so that your PC will run better. GTA 5 is much more CPU intensive compared to GPU, as it is playable on a 512MB GPU and will still run fine without LAG or anything at the lowest settings and resolution, however, the CPU plays a much bigger role in it. In GTA IV if I change shadows from medium to high I get 20% more CPU and GPU usage. Hopefully medium shadows don't look atrocious on this one! Hopefully medium shadows don't look atrocious on this one! Particles Quality - Very High. Grass Quality - High (One of the most performance-intensive settings. Setting it to Ultra can drop fps by 10 when moving over grass) Soft Shadows - NVIDIA PCSS a) running the game code (main thread plus branching threads), and. b) sending draw calls to the GPU. The CPU will execute these tasks as quickly as it is able. A CPU often uses less than 100% of its capability because the main game code thread runs on a single core so it's limited by the speed of that core. Grass quality: normal to very high. Soft shadows options: softer, softest, AMD CHS, Nvidia PCSS. Post FX options: up to ultra. Motion blur strength: scaling bar. In-game depth of field effects: on yOIc.
