I must say that overall performance has improved loads compared to the previous games. I have max settings with no issues. Where as Max settings in GTOS would really slow the game down.
Though still not that happy with Anti Aliiaising. If possible we need more choices in the otpions for it..as it certainly doesn't look as max as it can go.
Yes the performance has improved> I'm quite happy with the visuals out the box...it all depends on your system and settings, graphics card and ram. Mind you I'm a notorious tweaker always fiddling around with game settings
