Re: New Laptop. Sims 3 won't recognise video card and hardware
@pigsquiggle Did you repair or patch the game after you did the edits? That would revert both .sgr files to their original state. None of the three edits had any effect, even the one for texture memory, and that should work regardless of what card you have.
Please search your entire computer for "graphicscards" and see if you have a second copy somewhere. It's unlikely, but I did see someone once who had two copies of the game installed somehow and happened to be editing the file that wasn't being used.
