ok well what you do it goto start, all programs! then look for rivatuner but dont click to start that, and at the top there is D3D Overrider, start it then use the global settings, force tripple buffering on and v-sync, good luck and let me know if it worked!
Btw, do I just run the programme, and then I can start the game, or do I have to add it to a game if you know what I mean?
