I was running 3dmark...I disabled vsync and antialiasing, and also chose to use my adapter default, in the refresh settings, instead of setting monitor at optimal. I came out with my highest score, 9007, so far on the gf4 ti4200 128mb. This was an increase from my last highest score of 8972. I'd like to continue using this setting. Question is...is there a down side to using the adapter default for refresh rate?
