Hey, everyone. I'm running UP2.01 on an AMD 2.2x4, 8gRAM, Nvidia465, with TrackIR. When I set the monitor refresh rate at 60Hz I get super smooth game play while flying and only minor dips in FPS when fighting...but there's stuttering every 10-20 seconds. Setting the monitor refresh rate to higher numbers eliminates the stuttering, but there's a greater decrease in FPS with effects, and the game doesn't feel as fluid or smooth. Could someone explain to me why this is the case? I've tried assigning different core usage, overclocking the GPU - core clock/mem, using different/higher memory .exe's, turing off services and background stuff, resizing textures, lowering graphics...nothing seems to work though. Why would the stuttering stop at anything above 70Hz? Thanks.
