    No, but you can only delete that file while X is not running. All amdcccle settings are stored in it.

    screen sh -c '/etc/init.d/lightdm stop;sleep 5;rmmod fglrx;rm -f /etc/ati/amdpcsdb;/etc/init.d/lightdm start'
    Will I need to re-install catalyst after this?

    And with Dota 2. I have 6970 and I have fps drops at start of the game near fountain to 30fps and when I'm choosing hero, but it is only for first game. After first game no drops and I'm running 55-60fps all the time. Latest catalyst.

    Maybe a dota 2 player can comment, i'm thinking it could be a game setting or a bug.
    A google search is showing tons of people with the same issue.
    Can you tell me, how much GPU Load % you are getting?

    I'm getting 30-50 (avg 40) fps on Dota 2.. with GPU Load stuck at 42%

    I just ran dota 2 to investigate with fglrx.
    It seems I get around 60fps at 1920x1200 highest details with drops to around 30 lasting only a small time (usually when something explodes or the level ends).
    Maybe the drops could be related to disk drive loading things, or shaders/cpu stuff.

    And CPU is Sandybridge, that should use intel's pstate... not have much experience with it but i will probably try to disable that to see how it goes without it... probably booting with intel_pstate=disable kernel parameter is enough to disable it for safe testing
    I didn't have intel pstate driver installed in the first place, so I installed it and tested it on powersave and performance profile.. with intel pstate It felt like there were less violent fluctuation.. but the average fps stayed the same.

    Contrary to what many nvidia users want to say fglrx and the open drivers for radeon aren't horrible.
    I don't experience any performance issues and advised someone recently to purchase the same card you have, which he likes.
    All linux.

    What resolution are you running these games at ?
    I'm currently running games on 1440x900 @ 60Hz on my main monitor.
    I checked some benchmarks and reviews from users, The performance shouldn't be what I'm getting... Since you have basically the same card and not having performance issues..
