    Radeon 7770 + Catalyst = unusable for gaming


      I can't play games with my 7770 under Ubuntu 13.10 (and Ubuntu Gnome) because there is always some kind of input lag (mostly pretty severe) and very low fps in games which have way lower requirements than 7770 - TF2, Dota 2, Xonotic, some Wine games, even Unigine Benchmark has pretty terrible performance (10 - 20 fps everywhere).


      I had better performance with GeForce GTS 250 (from 2009 >.< ) than with 7770, by like 150-200% and no input lag or other bugs.


      I tried:

      1. Reinstalling whole system.

      2. Latest beta, beta before and those drivers from Ubuntu repo.

      3. 3.12 kernel.

      4. Changing options in CCC.


      No change. Oh and Vsync is off in both CCC and games.

            I also experience unreliable gameplay performance with the AMD Radeon HD 6790 on Ubuntu 12.04. It is mainly with the game Left 4 Dead 2 that I've tried it so far. I get stuttery performance during the map intro scenes (both video and audio), as well as intermittent input lag during the gameplay itself. Sometimes, during an online game, I will press left-mouse button to shoot, and it will start firing one or two seconds later.


            Up until one week ago, I was using the Nvidia GT 240 graphics card (1GB GDDR5), with the latest stable-release Linux drivers. I experienced no such performance lag.


            I play with Vsync on.


            Hopefully this will be addressed in upcoming driver releases. However, thank you for your efforts thus far, AMD Linux team.

              AMD should start treating their Linux customers a little more seriously. This is AMD customer support response to my ticket, ticket in which I've provided same information as in this thread along with Xorg logs:




              What the hell? No wonder AMD Linux drivers work so bad.
