we have 3 brand new mac pros with that crappy ati card. the performance is unacceptable when working with maya. the whole scene handling is soooo slow. as we use xp64 there is no workaround in sight. the old 7.11 is not available for xp64 and all tweaked drivers do not support xp64 too - what paid ati to be the default card for a mac pro machine…guess we will have to buy 3 new nvidia cards and burn the ati crap..

I've tried NGO optimized ATI driver. It works awesome with my x1400. Selection is INSTANT =)))

Where is the page http://www.cs.usyd.edu.au/~tapted/slow_glselect.html gone?!?

I've got the same issue with Maya 8.5

The selection is SLOW and not only that but if I have multiple objects in a scene the only ones I can physically select are the ones at the top of the outliner!! Whats crazy is I can now use High Quality rendering which is great for viewing normal maps, but the other issues make the program unusable. I found downgrading to 7.11 is a great fix, but I want HQ rendering!!

Curse you ATI, I will never buy you again!

Hubert all you need to do is copy the atioglxx.dll driver into the blender folder and blender will use it ( http://blenderartists.org/forum/showthread.php?t=120670&highlight=atioglxx )

Strangely enough, Blender runs at near-full speed on Linux, the select function works perfectly fine. Even more awkward is the fact that the ATI Driver slows down nearly every other single aspect of the system.

Ah well, it still works. Maybe I'll just downgrade back to the original Intel driver for my Windows.

Sure, be careful. Using months or years old drivers is not a solution, but a hack, a workaround. You have to know what you are doing when applying this. May interact with other software that uses the graphics card intensively.
So if Ati, one of the tow biggest suppliers of graphic cards, most probably isn't changing on their side in the forseeable future, the problem is on the other side, Blender's, even if it is not Blender's fault.

One note: Be CAREFUL when doing this. There are many times people switch out drivers and do the wrong ones, yet still appear to get a speedup. This is because the new drivers are in software rendering mode, which can be faster then the old drivers in some situations (e.g. selecting) but much slower in others.

Make sure you get the drivers for your card.
