I've tested precisely again, in the hero demo map, using Legion Commander and monitoring fps while the game is paused, the little pool at the bottom left being visible. With everything on except ambiant occlusion and V-Sync, I get 70+ fps in borderless window mode at native monitor resolution. With V-Sync on I get 60 fps. Once I switch to full screen mode, I get 30-35. I get the same 70+ fps without V-Sync. It's like the screen refresh rate was most of the time (but not always) set to 30 in full screen mode. \r\nI even recorded a video of the issue, but I would take some tome to upload given my internet connection.
