Hi All I'm having trouble with the graphics when playing games using parallels. Most recently this problem is for Civ 5. The game works fine, but there are a lot of black patches where certain elements should be. It's usually scenery that's missing. The outline is there, or rather the graphics round about are there, but how the full picture. Is anyone else experiencing similar problems or have any suggestions about how to fix it. Have just upgrades to version 6 to see if that helps but same problem. Any help much appreciated. Thanks
