Has anyone Played CS:GO on Linux, I am thinking more of using Fedora. Any known issues?Issues I know of that are for about 99% of the games out there is that there is no DirectX for Linux, so your stuck using OpenGL which creates a serious performance hit to gameplay framerate etc as well as bugs show up.

I ran World of Warcraft through Linux MINT 13 using WINE 1.4 and got it to run, but my frame rates were down in the dirt with 9 to 15 frames per second as well as shader bugs and texture layers in the game would appear/disappear so changing camera angle for example while standing in the auction house in Stormwind a city on the game would cause everyone to lose their skin and be a black void with hair and clothing on. The funny thing though is that Night Elves with the glowing EYES showed as black voids with glowing eyes. This same computer that I tested for gaming with Linux, I had another hard drive already set up for it running Windows XP. For comparison purposes, I booted Windows XP SP3 and launched World of Warcraft and had good 40 to 60 frames per second because I had DirectX to use the full potential of the video card, as well as no bugs.

Until someone makes an open source DirectX module/addon for Linux, its crippled for 99% of the games that are out there 

If I were you, I'd give it a try, build up a system that has plenty of hardware resources to play the game if it were Windows, and instead install your choice of Distro, and then install Wine, and then try the game on Linux and report back with your findings. You may want to dual-boot to be able to test same as I did between Windows and Linux for the same game. When doing this you would want to install Windows to a fraction of the hard drives size such as you have a 160GB HDD and you allocate 80GB to Windows NTFS partition and then leave the other 80GB free and unpartitioned. Then install Linux and choice to install Linux to this free non partitioned 80GB space and have it use a bootloader like grub etc to give choice on boot for Windows or Whatever distro of Linux you install.

*One thing that I did have to do for World of Warcraft that you would also likely have to do with CS:GO is copy the entire contents of the game to an external hard drive, and then import it to the Linux systems partition, then set up the EXE that is associated with the game to WINE so that it runs the game within WINE emu environment. I have yet to find sold in store CD/DVD games that will allow for you to install them to Linux the same as you would a windows computer. And if the games have registry entries the games will likely be broken as well on the linux side. World of Warcraft does not have any Windows Registry HOOKS to it like many other games that like to anchor to it with antipiracy features etc. With WoW the antipiracy feature is as simple as... you dont pay us your monthly membership ..... we dont allow for your credentials to play the game! STAND alone games are more prone to registry hooks to anchor that game to that system so that one friend cant copy the folder contents to another friends computer and run it etc.Did some research and it seems as though some people got it to play through WINE, but not sure of how well. The good thing is that the Steam Client is working to port games for Linux, so maybe they will port this one. Although if ported not sure if there would be a performance hit since there is no DirectX.I am GOING install Fedora and SEE how it works. Playing cs was one main reason why I didn't full set my HDD to Linux and fully uninstall windoze.
