    On Windows I have stable smooth 60 fps (Vsync on) even in big battles. But on Mint I have 25-30 FPS with same video settings.
    Is it possible to do something to increase FPS? I have Radeon HD7770.
    Help me please. Dota is the only thing why I'm not fully on Linux
    Using the 3.16 kernel should give a big boost to your FPS, although i doubt it goes all the way up to 60.

    • My glxinfo is

      Now I still didn't ever try to install another kernel, so decided to try other ways that you guys gave me.
      As for the DPM - it's enabled. I checked dmesg log and there was a string that you mentioned.
      Launching Steam with vblank_mode=0 force_s3tc_enable=true steam and disabling Vsync also didn't help
      A trick with 99-vblank.conf file also didn't help
      Adding command radeon.vm_block_size=12 to grub file failed, I don't know why
      Here's output
      Code:
      # gedit /etc/default/grub
      # update-grub
      /usr/sbin/grub-mkconfig: 13: /etc/default/grub: radeon.vm_block_size=12: not found
      As for R600_DEBUG=hyperz string, I didn't understand where to place it. To grub file?

      So tried everything except another kernel. Will try to google now how to install it. Big thanks guys for your support

        Why not just make that a steam launch option for the game?

        Code:
        vblank_mode=0 force_s3tc_enable=true %command%

        • Updated kernel to 3.16 RC4. No changes
          P.S. Can't edit previous post

          • Hi all,

            I've added this repository on my Ubuntu 14.04 64-bits installed on a system with an AMD APU A10-6800K (richland, comes with an Integrated HD-8670D). It works pretty well for daily use (I'm not a gamer), however I'm unable to run Firefox with Hardware acceleration. It's this known on the current state of the drivers, or it's there something I'm missing?

            Thanks.

              The radeon.vm_block_size=12 boot command should only work on 3.16+ kernels btw, but it's inserted in the same area as the quiet splash commands (so that area should have quiet splash radeon.vm_block_size=12).

              As for R600_DEBUG=hyperz, you use it in the same way as vblank_mode=0 (they're both enviroment variables).

              I'm not too up-to-date as to the state of the 7770, but it could also be possible the open-source drivers just aren't up to par on it (although I doubt that's the case). Might need someone with such a card or someone more knowledgable to chime in. I know Dota 2 works great on my 7850, but it was pretty sub-par on my 7660G + 7670M laptop with supposedly more-mature open-source drivers (not radeonsi; apparently 6xxx rebrands) last I checked...

              • Hi! Sorry for a late reply. I did everything what you offered, but nothing helped. And that's very strange for me....

                • Hi, cann't install this drivers

                  I did
                  Code:
                  apt-add-repository ppa:oibaf/graphics-drivers
                  apt-get update
                  apt-get dist-upgrade
                  apt-get install mesa-vdpau-drivers
                  then i try to start "steam" or "LIBGL_DRIVERS_PATH=/usr/lib/{different here} steam"(i don't know what i've to add as PATH)
                  and steam says
                  Code:
                  libGL error: unable to load driver: r600_dri.so
                  libGL error: driver pointer missing
                  libGL error: failed to load driver: r600
                  libGL error: unable to load driver: swrast_dri.so
                  libGL error: failed to load driver: swrast
                  I have Radeon 7670m + 7540G and I have dancing lines when I start any linux with open drivers, so I'd like to solve this.
                  Could anybody help me?

                    As far as I remember this problem related to incompatibility between LLVM and Steam runtime dependencies (libgcc_s.so.1).

                    • Just a heads up, but it seems one of the more recent updates broke shadows on windows with Unity on Ubuntu with my 7850 (the shadows are like sections of a checkerbox). Not sure if anything else is affected or not, or what the cause is.
