Over the past year of owning an iMac, I have been quite happy with the games that I have available to play on the OSX: TF2, Portal, WoW, SC2. While these games are great for me, I am kind of looking into the future and there are a few games that will be running on Windows only, such as Guild Wars 2. I know about BootCamp and that is the most fool proof option, but I was skeptical about the WINE usage in CrossOver. I would like to stay in OSX as much as possible and this would allow me to still be actively connected to my email and other OSX applications while running a game. My question is, for those that have been using CrossOver, what has the performance been like for more recent games like Call of Duty: Modern Warfare 3? I expect the performance gets better and better as bugs get fixed, but what are people actively achieving for FPS on what equipment? I see CrossOver has compatibility charts but there aren't really any feedback as to the FPS or latency. I hope to resolve my decision before I partition and purchase a Windows version.
