I use parallels to play a free mmorpg game called Tibia. I play this by enabling direct X acceleration and by forcing tibia to run using direct X 5. In parallels 4560 this works perfectly under coherence mode, but after testing the beta I found that it does not work anymore. The game window is very unresponsive and unplayable. Im going to download 4560. This is not a complaint, simply a bug report I am running windows xp on a macbook 1.83ghz core duo with 2gb ram
