i found the fix bro. Here's what i did :
- Go to Nvidia Control Panel, lock the FPS at max 60.
- Go to C:\Users\your_username\AppData\Local\EA SPORTS FC 26
- Find fcsetup.ini and overrideautodetect.lua
- Set all settings to low (0) and max_frame_rate to 6. You can adjust any other setting (idk if it will break the game, but i set it to all lowest)
- Set the file to be read-only.
- Copy the overrideautodetect.lua to C:\Users\your_username\AppData\Local\EA SPORTS FC 26\settings as well.
With these steps i'm able to play the games without dropping to 5-10 fps. Hopefully it helps!
