--- Comment #13 from Andrew Eikum aeikum@codeweavers.com 2012-03-23 14:24:43 CDT --- No, I don't. I tested with the demo I found here http://www.fileplanet.com/129916/120000/fileinfo/Homeworld-2---Demo. I have to launch it with the "-nopbuffer" switch. You could try installing that in a clean prefix and see if it's a problem with just the full game.
