--- Comment #5 from Sylvain BERTRAND sylvain.bertrand@gmail.com --- In the lastest dota2, I tried to enable vsync.
When I do so, once I close/apply the options, the display gets corrupted. Then I exit (guessing where the quit button is...) the game, then when I start again the game vsync is still not enabled.
