    Hello, everyone. A while ago I owned new GPU - GTX Titan, but before I had GTX780 and had same issue.
    At first I thought it was the problem of old GPU but with Titan I still have same issue.
    It appears only if I work in Adobe PS CS6. Sometimes (honestly it is often enough, thats why I am writing this post) artifacts appears on my working zone, it dissapears if i move picture but after few seconds can appear again , especially I use any "brush"-kind instrument. Really annoying. I can work with that but maybe exist solution to fix it?


    Oh, my config
    cMP 2010 upgraded to 2012 12-core 3,46Ghz
    128GB ECC DDR
    GTX Titan 12Gb - PC vercion w/o mac efi (my previous gtx780 has mac EFI, made by macvidcards)
    3x1.5TB HDD
    startup SSD 256GB

    Do you use the native driver or the web driver?

    Is this artifacts occur in both drivers?

    With 780 or 1st Titan, you have luxury of switching with a couple clicks and a reboot.

    Give it a shot.

    I found another issue in Titan, I dont have with flashed GTX780 - all highlightened areas in Capture One Pro becomes purple in rendering. Have no idea how to deal with this - disaster. Do you have ability to check if your flashed Titans, have same or not? Thanks.

    Purple **** solved! Just had to turn off using OpenCL mode while rendering. Seems non-flashed card does not support that. Does flashed card support it?
