this is kind of a petty complaint, but
basically now when i switch between windowed and fullscreen the screen either goes black or the game window disappears entirely for 15-20 seconds, previously it switched nearly instantly. running thru steam makes my game run poorly so i like to run windowed a lot of the time if i'm talking to people on steam, switching back to full-screen if i need to GET IN THE ZONE AUTOZONE
this only started happening with the latest update. on the plus side, i can now minimize without the game crashing, but i still prefer windowed.
