fact: it did always run good only you have stopped playing RoF for a while.
You have the last GFX,( I guess the Videocard drivers and not somekind of car), for this old directX9 game.
Uninstall you Videocard drivers, by using http://www.guru3d.co...moval-tool.html
so you are sure everything will be removed on AMD/nVidia/Intel drivers.
Let Windows install his own Vcard driver and test again.
If this is still not working the do the same uninstall step and now go to the Vcard manufactor website to download his driver.
The whole problem is that new drivers do not have a decent support for DirectX9 that was introduced wayback in time, for XP 32bit. Think that could be the problem.
edit: Let us know if it worked.
