Do what the top answer here tells you to do and copy and paste the info you get:
Also where did you get your drivers from?
yaourt
What package did you install?
ati legacy drivers, drives ae correct. THere are no problem in any other game
Post your uname
And post the info from the guide.
@spidernet from looking at his post history he built the driver, from AUR or AMD I am not sure.
Yeah I was going to make sure he installed the correct legacy driver. But it seems he got the right one.
It might be an inssue between CSGO and the legacy driver.
uname just post linux
-a that has to go after uname
Linux 4.4.1-2-ARCH #1 SMP PREEMPT Wed Feb 3 13:12:33 UTC 2016 x86_64 GNU/Linux
If you have catalyst control center turn on tear free desktop.
Or put this in the terminal
aticonfig --set-pcs-u32=DDX,EnableTearFreeDesktop,1
problem stil exists, but in a lower degree
I dunno man I have no idea how you set up your system not to mention you card is almost 9 years old.
You could for shits and giggles see if you have the same problem on another distro. If not, it is something with your settings, if so, you have a card that uses old ATI spaghetti code.
system is configured in very simple way with all the propdrivers installed. I can also run WoW with Opengl at 90 Fps. so i dont know either
Are you running the native CS GO?
You could try it in WINE and see what happens.
if by native you mean for linux-os then yes
Maybe check your ATI config

Or see if you have the same problem in another distro
Or look at picking up a more modern GPU
Scratch all that,
Try this:

already did these changes :/
Maybe it is time to look at a upgrade.
It won't be able to support upcoming Vulkan, DX12, DX11 or OpenGL 4.0+ games.
