FPS AND FRAMERATE:
– this is really obvious but needs to be mentioned, it’s imperative to limit the FPS (frame-rate) of your game to give some CPU to other apps running on your PC.
– THIS IS A BASIC RULE IN SIM RACING – Of course apps eat CPU as they are running on your PC and obviously if you didn’t cap the framerate in the game settings there is a big chance that the game will eat all CPU available and to not have enough CPU to run all things together,
– if your Monitor refresh rate is 60Hz/120Hz/144Hz, V-Sync should cap your frame-rate but beware on low-end PC do not activate V-Sync if your monitor sync at more speed than 60Hz.
