I have had about 50% of my matches crashing to desktop when starting. This happened to freshly started clients, too. In addition there was the standard black screen (the one you can end with alt-f4) from time to time and a total black screen that freezed all input devices and made me hard reset the system.
Furthermore the overall performance of the game got worse again. Running with lowest settings and FPS are now close to unplayable (arround 20 FPS, with drops down to 10 and worse) and often video freezes for 1 or 2 seconds.
