I have the same problem, 100% usage on one core and about 35% usage on
the other with HD material with an Nvidia 6200. My confusion with the
wiki is which 'SyncToVblank' options should be on? I have:


I already have "UseEvents" "true" set. I've tried both the current 100
driver, and the last 96 series with no change. I am using realtime
priority, the nvidia AGP driver, and everything else I could think of,
but CPU stays skyrocketed with HD.
