First impression, Fantastic!!
The only negative I've got is that I'm going to need a more powerful computer. I don't think I'm getting even close to 60 frames per second and its juddering like crazy with just about every demo. Tuscany is the only demo that seems to run smooth. Did go through 'Titans' and that my friends is epic (even with juddering)!
Got my fingers crossed for all still waiting!
Great time to be alive!!
