Apparent problems with DXVA? on Dell XPS M1730

still can’t find optimus, I’ll ask @Noir

I tried to chenge the settings for vvvv in the nvidia cntrol panel but I don’t have a gloval “best performance” choice.
So i did some tweaking and it got a slightly better performance, i think (anyway vvvv crashed).

I really don’t understand how it’s possible as before changing the hardware everything worked great,

I’l run my intallation on a friend’s computer but I relly need this computer to get back on track. I’ll post more when I have news, does somebody think that a clean install of WIN7 would help?

Ciao for now.
