Choppy OS X Screen Savers


In Mac OS X 10.0.4 on my iMac 333MHz, 192MB RAM and a 6MB ATI card the OS X screen savers do not flow across the screen. The images should disolve and fade into each other but instead they move in small blocks at a time....very choppy. Anyone know how to correct this? Thanks.

Quit the other apps you're running could help. Or switch to a lower resolution. Some things jump on my G4, so it's only to be expected on an iMac

I'm CERTIAN that the actual, "problem" is the fact that OS X 10.0 - 10.0.4 don't support ATI Rage II/Rage Pro Hardware/OpenGL calls so all rendering is done with Software. Hence the lag time. Hardware, or accellerated, rendering for the ATI Rage Pro (The Graphics card in YOUR machine [333 MHz iMac]) will be available with the 10.1 update. This is detailed in Apple's until recient TILs/ADC and the limitation is noted in Mac OS X's online documentation. Only machines with the ATI Rage 128 or NEWER are currently (10.0-10.04) supported.

Quitting apps or reinstalling OS X will accomplish NOTHING for you.

Simply wait for September. The "current" builds (5D15 - 5G2[X/5/6]) floating around on Hotline/Carracho do NOT contain the updated drivers, so don't bother. In any case, it's illegal to distribute them.

Yes, I'm ADC. Ask no further questions...

Yeah, on my G3 266 with the supped-up onboard video (ati/6megs), The screensavers are pretty bad. I leave em off - it makes os x look bad.

Anyway, my rage orion card (16megs) works *much* better. I don't know how well its supported/accelorated, but it runs screensavers incredably better. Remember, I think the macosx screensavers are open gl, so even the picture/slideshow screensavers are cpu-intensive.

And using both my frame buffers at once is cool, but they tend to slow eachother down sometimes.

So is a GeForce 2mx going to be accelorated in 10.1?
