So I was playing Counter Strike on Ubuntu 14.04LTS and I was only getting about 50FPS with my AMD RadeonHD 7970. This is extremely low, in Win7 I get 200+. What is the problem? I believe I have the right drivers Ubuntu automatically got the open source ones when I installed it.

That's why. The open source Radeon driver isn't as good, I think, as the fglrx, or proprietary one.

If your card is supported by the fglrx driver using your current kernel, then you can try using that and see if that helps, or you can try using the instructions here at your own risk.

Let us know how it goes...

Regards...

Idk if I did something wrong but I installed the fglrx driver, switched to it in the "Addition Drivers" in Ubuntu, and I got an even lower framerate.

I guess it doesn't help.

I'm not sure what to suggest, at this point.

Regards...

Hi there Jonf,

I am also running 14.04 Kubuntu (KDE instead of Gnome) with the Radeon 5450 HD. I get some decent FPS on some games and other not so great. What a lot of people forgot to ask about this is your method of running Counter Strike on Linux. Meaning are you running the Linux version of Counter Strike or the Windows version under WINE overlay?

If this is a WINE overlay then dang 50 fps is great! However there is an issue with the propitiatory AMD drivers for 14.04. In a nutshell, they just don't work yet. This is why I have my system dual booting 12.04 (with the drivers installed) for playing and 14.04 for working and getting the bugs out. Eventually I will migrate everything into my 14.04. I know this OS is one year old and still has some work to be done.

Here is my 14.04 set up on the GPU;
Open GL reports, 3D Accelerator is unknown, Driver Vendor is X.Org, Renderer Gallium 0.4 on AMD Cedar, OpenGL 3.0 Mesa 10.1.3, Kernel is unknown.

I have a 7950-based card (R9 270X) and I get the same FPS on almost all games. Of course, Counter Strike doesn't need WINE because all VALVe games run natively on Linux, even CSGO.

The only game I have problems is EuroTruck Simulator 2.
