Possible quick fix for ATI graphics card and v e r y s l o w B l e n d e r.
Have been missing blender because it is so s l o w on my new laptop with ATI Radeon card. OK, I have may have found the solution. First I tried every form of ATI driver and catalyst with absolutly no change. HP said try catalyst, ATI said it would not work on laptop. It seems that Microsoft does not really like OpenGL yet, < they like directX> but I understand that the new Windows version will be much better with OpenGL. The solution is to go to display properties, lower graphics acceleration to one step above the lowest… now blender flies again with no loss of quality. When I am done blending, I just raise the acceleration and then all of the the ATI controls return. YEE HAAAW… I CAN BLEND AGAIN.
Thanks for your help, just thought I would pass this along.

correct, not using hardware acceleration will cause this bug to disappear

it will also make blender a lot slower on more than moderately complex scenes

Damnit, you got my hopes up

that fix is’nt really a fix

lol :smiley: Open GL is like 10 years old, and it doesnt have anything to do with bad windows support. In fact, when you disable hardware Accelaration, instead of the ATI/nvidia Open GL driver, the standard Windows one is being used, and it speeds up blender sometimes.

Open GL is an evolving standard. Microsoft sees OpenGL as a threat, and wants to kill it.

That said, this is an issue with ATI not making their cards compliant.
