In Q.U.B.E. 2's Aftermath DLC, I was trying for over an hour (and over a a couple hundred attempts) to get the gold cube in puzzle room 8 of this video (at the 45:00 mark in that video). No matter how many times I tried to make the jump, I would come up short. Finally, I remembered another game requiring V-Sync in order to work properly, so I went into the video settings screen in options and enabled V-Sync, and now I can make the jump every time.

Has anyone else had any issues playing this game with V-Sync disabled?
