MacBook Air :: 10.6.3 - Huge Graphics Performance Update To OpenGL?

I have been reading that several people are seeing much cooler temperatures on their Mac notebooks and they think it's due to better graphics drivers with the update to 10.6.3. I however thought about the huge performance hit in OpenGL going from Leopard to Snow Leopard (probably same thing). So I decided to check my OpenGL results after installing 10.6.3. However, I didn't check my xBench results before upgrading to 10.6.3. I went and found an old result which shows 67 points for "OpenGL Graphics Test." My new result for "OpenGL Graphics Test" is 111 points. When I check the xBench archives, people with rev "C" MBA's with 10.6.2 all show OpenGL Graphics Test scores in the 60s.

If this is correct, we could all have some big improvements that really show huge effects on the MBA. It should help everyone running Snow Leopard. It should lead to graphics performance gains and lower heat due to graphics demands. Could someone else running 10.6.2 on a 2.13 GHz CPU MBA run an xBench test before the 10.6.3 upgrade? Then upgrade to 10.6.3 and run another xBench test. Then please report back here with your results for OpenGL Graphics Test and hope this result is great for all of us. I believe this would be a big improvement for the original MBA too?
