Well I'm currently playing Battlefield:2. on a Win-Box. I tried to get it to run on ubuntu with little success. The frame rate was a total disaster and punkbuster wouldn't work. Without Punkbuster you can't play online properly. With all of the settings at minimum I could get 15fps! The same hardware under WinXP I have the settings maxed out completely and I'm running 60-80fps.
The clan I'm in are starting to scratch around for a new game, there are a couple of hopefuls coming out soon. I really hope we go for Quake Wars, this will be out for Linux about a month after the PC release. The game looks really cool, lots of team work not a fragfest. Also it's a game that doesnt require DirectX 10 to run so the guys wont feel the need to run Vista. It will also open the clan to new members that run Mac's and Linux. More the merrier

I like diversity, it makes for a more interesting clan life...
Anyone interested in BF:2 or the possibility of playing Quake Wars once it's out, drop by our
forum for a chat. We are a UK based fps clan, the min age for membership is 21 but most of us are around 40. A bunch of weekend warriors that spend their evenings chatting on teamspeak, playing BF:2 and often getting a little drunk... Think of it as a virtual pub, well that's how we think of it.
