I agree, Call of Duty 4 must be the game most people want to see up and running on linux !
I have it on windows but would love to be able to play it on Ubuntu.
I only just now discovered PlayOnLinux and have installed it and tried to install COD4 but it won't let me. I obviously thought it would be as simple as clicking on 'install' and it would seamlessly work.......life is never that simple is it?
I have Wine installed v 0.9.46. Also, do I have to have POL running before I try to install the game, if so, how do I start it as I can't seem to find it anywhere, although it is installed?
Any other help that anyone can provide to get COD4 running will be so welcome.
Thanks
