i just did a complete reinstall of windows, and used the included CD with the motherboard which installs everything in order, and it still does not work. it never switches graphics modes, and neither virtual vsync nor switchable graphics works at all. it will simply use the onboard GPU and the frame rate plummets. neither the latest versions online nor the included CD works..
that was the main thing i wanted when making my motherboard decision, and it completely fails to work at all. at least i got the board on a deal ($105)
but i did lose a lot of hours in troubleshooting something that refuses to even remotely show that it's even TRYING to do something. in all honesty, i've never had to troubleshoot so many things on an amd machine before. all the way down to mounting heatsinks is rocket science (on this board at least), because of having to mount a bracket on the back of the board which has 2 different size holes for mounting, and 2 different screw sizes. and then i had trouble getting my sound card to fit in the pci slot. and then i found out there were at least 15 different bloated driver sets i had to install just to get things working. and on top of that, one of the driver sets killed my AHCI setup, and i had to do a system restore just to be able to boot to windows.
