To be honest, my linux Laptop has been running steam just fine for quite some time now.
I have been looking at games that run on Linux, and sure, there are some right dogs out there, but therte are some great ones too! - Half life series, DOTA 2 etc, but also with Wine, I amstruggling to think of a game, that I have, that I have not been playing just sweet on Linux.
I have little use of my left hand anymore, and so I am limited to what games I can play these days, so FPS games are off the menu ( Devastated ), but thankfully, I am a Massive Dawn Of War lover, and so, they also play well under Wine.
I really do wish that they were also developed for Steam under Linux like they are in Windows.
AMD issues under Linux?
I find this rather odd. MY Linux Laptop is running ATI Graphics and its spot on. My Windows Laptop is running Intel+nVidia and when I tried it when new, I had issues, and so its been Windows ever since, but the Linux one with ATI is great.
Similarly, my Linux PC is alos running ATI graphics, and that too, I have had Zero issues with. Admittedly, 7770 so, not the latest card I admit, but Im nto a heavy gamer, and those cards do all my games better than I need them to, so...
