Resolution problem

Everytime I start the GP2 2005 mod the resolution is 1200x800, but I need 1024x768, so I change it. But the next time I start up the mod, it is again on 1200x800. How can I solve this?

go to your f1graphics.cfg and then change the res to 1024*768 like so

1024 ; [RELEASE] Game 3D Horizontal Resolution
768 ; [RELEASE] Game 3D Vertical Resolution

or if that doesn't work then put/copy that f1graphics.cfg in this folder

C:\Program Files\Infogrames\Grand Prix 4\GPSAVES\Carsets\GP2 Season 2005\Data\Files

Thanks!
