    Hello,

    since 9.9 the fglrx suffers from strange OpenGL perfomance regressions and other flaws.

    As soon I am using compiz, the card shows a high load and almost never clocks down anymore.

    The fglrx driver doesn't affect the performance regressions I have noticed.

    Hello,

    I have used "conservative" for a while and it really affected performance.

    C'n'Q on, C1E off

    System Idle: SSD 150 - 170 MB/s, ETQW 33 fps
    System Full Load with prime: 180 - 190 MB/s,...

    The governor is already set to ondemand.
    Only Intel's advanced C-steps affect perfomance.

    Speedstep's perfomance loss is around 1%.

    It is known since years and is not fglrx specific. ATI cards are always using Video-Level (grayscale 16 - 235) for HD-Resolutions when outputting Video.

    Great, 9.9 downsamples Icons, Fonts ... to gain performance while switching Desktop.

    Fixing something, which has never been a problem by making it look ugly doesn't solve anything.

    That's not a fglrx specific bug it happens with Windows too. ATI always uses Video-Level for Videos and there ist no way to configure it to PC-Level.

    Hello,

    I've got the same problem with a Lenovo T61 and NV140 Quadro GPU. The X-server starts, just the screen remains black, it looks like the display gets turned off.
