Our friend Periscope suggested nHancer tweak as a probable solution and he was right: nHancer solved the problem and save my day!
Yeah, Nvidia also can show the same image quality present on ATI cards: itīs the most obvious supersampling (SS) AA modes that are hide on the Nvidia drives!
This will bring some FPS hit (from 20 to 60%, depends on the SS AA mode that you will use - and nHancer provides a lot of them) but for these new cards and rigs this isnīt a real issue. I also didnīt test these new settings with others old sims but the result shall be the same good one. And after all that i become to think if new Nvidia cards have really more FPS than new ATi cards with AA enabled or are just only cheats???
I will try to write a special guide for Nvidia&SH games&ImageQuality using nHancer and will post here.
Thanks again Periscope!
