Hi everyone, I'm a totally new on linux. At the moment my linux distribution is ubuntu 13.04 and my amd graphics driver its catalyst 13.04. I've tried 13.11 and opengl 4.3 driver but I had the same results over and over, this its my rig:
8gb ddr3 1600mhz
The problem its than in windows TF 2 runs with max in everything at 300 fps but in linux at 50-80, and the most anoying problem its with dota 2 that from 120(windows) get down to 40 with huge lag spikes to 20-25 making this competitive game unplayable.
PD: Sorry for my english.
Try using another driver. 13.3beta3 works in many cases. 13.6/7 has mouse lag. 13.8 memory leak. 13.10/11 *could* work (i did not test source games yet).
