Just upgraded my HTPC with the latest drivers 188.8.131.52.2321, after this i suddenly get a BSOD. After reboot i try shifting resolution/refresh rate with www.12noon.com/displaychanger and get a "no signal" notification from Onkyo amp. reboot again and try to watch television (Windows7 media center x64) and notice that picture quality is bad, pixel blocks, but looks like de-interlacing is better than old driver :-) . Time to revert to old drivers (184.108.40.206.2291) as this driver is a big bug, everything is fine now, only bad thing is de-interlacing! hope this will be fixed in the next driver..
