Why GFX card with more RAM?

I think you have probably answered your own question. It is not yet optimized. Right from the first release it has always been a mixed bag of pot luck as to which sytems could run it better than others. That is probably the case with most complex games but is far less noticable. Hopefully, with the next patch release, things should even up a lot more for everyone. Plus it is all a bit subjective. What I find acceptable might give another an apoplectic fit.
