    So I ordered a GTX 980 Ti and didn't even check to confirm that it had drivers ready - I guess I just expected it. NV's driver support remains excellent. Michael, do you want benchmarks, or are they going to send you a card? They should, you know

      It's been over a year now without them fixing this....

      It may look somewhat harmless but it demolishes any sort of desktop usability.

      Incredibly frustrating. Not a peep from anyone at nvidia despite numerous attempts to just get someone to say *something*

        Yes, the way the bug showed up for me in the end was that some UI widgets were not painting their last update. This meant that the text editor or the terminal often appeared frozen until you typed something. This sounds a bit harmless, but in practice was increasingly annoying over time.

        I played around with all debug options I saw in Clutter's code, and I found using this here in the environment worked best as a work-around:

        Code:
        export CLUTTER_PAINT=continuous-redraw
        This makes the thing run at a fixed 60 FPS (on 60 Hz screen). It normally only tries to update if there's something to update, so it might not be good for power usage, but I didn't see an issue on a desktop PC. Both the CPU and GPU load stayed low, both stayed cold, and the GPU kept staying in its lowest power state with reduced clocks.

          I have no problems with my GTX770 on Ubuntu with Unity. Haven't use Gnome for a while.

            looks like a gnome problem

                  I tried this configuration and whereas it really avoids the bug, it is really unstable, had 2 crashes in a row.

                    In this drivers in wine with dirt 3 have more performance since fall in 349 drivers however dont have same performance than 346.72


                    Wine 1.7.39 + 349.12



                    Wine 1.7.45 + 346.72



                    Wine 1.7.45 + 352.21





                    Other cases like as mirrors edge also up performance however stay close to 346.72 depending game scene


                    Wine 1.7.45 + 346.72



                    Wine 1.7.45 + 352.21




                    In dead or alive 5 last round performance stay very similar

                    Wine 1.7.45 + 346.72



                    Wine 1.7.45 + 352.21
