Windows XP---->Seven . missing #63 opengl

[orgelf]

Hello everybody !!

I just changed my principal hard disk for an SSD and decided to changed the os too .

I was on windows XP 64 bits and I work now on Windows Seven .

I updated my graphic card's pilot .

But I have some issue with sketchup .The realtime manipulation of the scene is slower than in Windows XP .

So i went in windows---preferences---opengl and I think I saw the problem .

In windows xp, when the three squares are checked (acceleration , texture and fast answer) I have the option #63 TrueColor AntiAlias 0. This one worked very fine .

Impossible to find it in Seven ....

Anyone got an idea ?

and i have another little problem, impossible to open the shadow window ! I can open the others but not this one .

Thank you very much for your help
