I installed the latest on my MSI K7N2GL mb with the nvidia IGP. I have 768 MB ram, 128 allocated to video, I don't run a separate video card. I "upgraded" from the Beta 4620 driver which worked ok except for slow startup.
Still blank screen at startup for about 30-45 seconds.
Switching to other consoles causes system lockup completely.
GLXgears figures are nearly the same for both drivers - apprx 2000 fps
I switch consoles frequently so this latest driver is now uninstalled, I'm back to the beta driver.
