Thread: Firefox 4 Hardware Acceleration is SLOWER!!

  1. #1

    Default Firefox 4 Hardware Acceleration is SLOWER!!

    I don't know what's wrong but hardware acceleration is significantly slower for me.

    I use this test to verify: Hardware Acceleration Stress Test.

    With hardware acceleration enabled (checked via about:support): 3 FPS

    Without hardware acceleration: 16 FPS

    Neither one is great, but why is hardware acceleration so crappy?!

    Info:
    Code:
    DISPLAY

    On the about:Support page under "GPU Accelerated Windows" it says 0/1 on my system so I think that means I don't have hardware acceleration enabled. Still I am getting 60+fps on that page you linked to. Strange.

    With 9800GTX (latest drivers) openSUSE x64 Firefox 4 RC and webgl.force.enabled and layers.acceleration.force both set to true I am getting about 25 FPS ... with them false/off more than 60+ FPS. So I guess I am better off with'em turned off (0/1).

    this seems like a question best aimed at the Firefox developers..

    i say that because here, i find that that Google Chrome is over three
    times faster than Firefox, and both Opera and Konqueror are four times
    faster..

    i used to have IE4Linux but it is so butt-ugly i haven't installed it
    on this beautiful version of openSUSE..

    anyway, it seems the Fox3 is a little piggy..

    60 FPS with default settings. If I change the setttings listed above my FPS drops to 30.

    I'll just leave things alone, they seem to be working just fine.

    If it ain't broke don't fix it

    I just looked in my browser settings without using about:config, just the browser options. Hardware acceleration is by default enabled where supported.

    So it is likely that when folks force options in about:config they are actually doing more harm then good.
