I installed Ubuntu 9.04 64-bit on a test partition that I have. I thought I would give it a shot and see how well it ran wine. For the most part it seems to run HL2 based games (i.e. Team Fortress 2) really well. After some tweaking the FPS is great on DX 8.1. The only problem is that after about 20-30 minutes of playing it would just exit and give me an error message saying "This application has encountered a problem and needs to close." I am unable to restart TF2 as it thinks there is already process running and it has a lock on the registry. Indeed, there was a defunct process I found with ps -ef so I have to kill it. I don't remember if I also had to reboot or not. I have Ubuntu 8.10 32-bit on another partition (so it's the exact same hardware) and I can play TF2 on that for hours straight without a problem. I'm not sure if it's a problem with Ubuntu 9.04 or the 64-bit wine but it happens every time if the game is running long enough. (I suppose I could install another 64-bit distro and see what happens) I have run into some other problems with applications not being supported on 64-bit platforms so I have just decided to continue to use 32-bit distros for now. ;)
