I run GTX 260's (2 in SLI). I have small performance on certain games. Is there a little tweak program or something techy I could do to boost performance on these cards? I don't mean to OC them. I just want to see an increase in performance percentage, if that makes sense. The current game is Dead Space 3 - in EVGA Precision's window, I see the top card utilized only 45% and bottom card used around merely 12%,.... tops. That's quite low. I remember seeing upwards of 75% performance on both cards while playing some other SLI- supported games. Sys Spec in case relevant is : AMD Phenom II (x4 unlock, 3.3ghz) ASRock 880G Pro3 with 8GB DDR3 Nvidia Driver 306.97 - I do have the SLI connector connected. I use the SLI hack, since these motherboards do not support native SLI. SLI seems to work fine however.
