Also instead of creating a shortcut and adding those parameters to the end of the target, you can just make a file called "commandline.txt" to your root Grand Theft Auto IV directory and put the "-norestrictions -nomemrestrict" and whatever else you use in there. That will make it so that you can still launch GTA IV however you want (through the shortcut, through Social Club, etc)
and joelzaar, the best way to explain the low textures is... creamy Everything else looks really clear, though, because render quality doesn't take much of a toll on your graphics card. It's the textures that are the hogs.
