Good Specs PC and Fifa 21 Lagging ? Fifa 21 directx problem fix.

– Try No limit on FPS & use Nvidia Control Panel Vsync 
– Go to mydocuments/fifa 21 open fifasetup file and change DIRECTX_SELECT to 1. Save and don’t go to launcher settings anymore because it can reverse it. Also first change fps in launcher to unlimited and force vsync in nvidia 3d settings for Fifa 21. It will help with menu and cutscenes 30fps lock 
– May be driver issue. If pc specs are met, then please update graphics driver.
