If I run the game on fullscreen, I am stuck at 50Hz refresh (running on a 60Hz monitor). This problem has persisted through 2 video cards, and several drive updates on each. So, it can't be that. What could cause this?
Went into my config.wtf file and found that the gxRefresh var was set to "50000/1000." Manually set it to "60" and now it's working.
