Ok, anyone with half a brain knows by now that Windows Vista irregardless of version needs 2 Gigs of RAM to perform at an acceptable level.
I have 2 Gigs in my PC. My daughter bought a new PC with Vista Home Basic pre-installed on it the Sunday after Windows Vista was launched.
Of course it came with only 512M of RAM and the hard disk drive thrashed constantly.
Being Dad, I ordered 2 Gigs of RAM and installed it. Performance was now fine, but unlike my PC with Vista Ultimate which shows that I have 2 Gigs, hers only showed 187.5 Gigs.
Weird? Where did that 128m of RAM go? Ah, I have a video board with 512M of VRAM and her low end PC has an ATI 200 in it which shares system RAM.
Guess what? The video minimum for the Aero look and feel under Windows Vista requires 128m of VRAM. So, even though Windows Vista Home Basic DOES NOT SUPPORT AERO, Vista grabs 128m of system RAM anyway!
Too bad Microsoft can't manage to explain this to consumers.
Or hire some decent programmers.
