Ok, thanks for help! I'll buy a GTX 480 in a couple weeks.. When I get it I'll make some tests and say the result...I'm afraid I can't test those scenes at the moment, but yes there is quite some optimizations on max, but in the 2011 and 2010 versions, if you get rid of ribbon and of that annoying floating camera gizmo you'll get quite an improvement, there is some other things you can deactivate, check the area forum, plenty of suggestions there. Drivers are quite important, of course.
Ribbon is useful I guess.. But not always, sometimes I turn it on for modeling when I use expert mode.
I don't know really what is this camera gizmo, but I'll look for those optimizations!
What forum/area are you exactly talking about?
Thanks man!
Cheers!
