I knew that Sims 3 would not run on my pc (over four years old and it was maybe middle-of-the-road when I got it, plus the CD-ROM and sound card had died and there was something making odd noises, so I needed another pc) which had a CPU running under a gigahertz. I made the best decision for my current circumstances and got a laptop after the new Windows came out. Sims 3 runs slower and slower, particularly since Ambitions. Saves take a long while to load and the graphics can surprise me with Sims sleeping in invisible beds and riding invisible motorcycles. It does load the missing graphics, first with the white shape, then the blurry version, then the sharp (as it's going to get) visuals. One of the biggest reasons I picked this laptop because I can double the RAM, though I'm putting it off. I've defragged, but I'd love to know from someone more technically inclined if it'll make a big difference to increase the RAM? It's not cheap, but I'd start shopping for it if it'll make a significant difference. By the way, loading saves from SV (for the Challenge) doesn't take very long at all, but the previous game set in Twinbrook takes a long time to load. The graphics issues I mentioned are worse in Twinbrook but seem to exist in both towns.
So, would doubling RAM to 8 GB from 4 GB (this is DDR2, if that helps) likely make the game run faster and smoother? Or am I stuck until I have the space and money for a new desktop? I really would appreciate if any of the pc-technically inclined would answer this. Obviously a real graphics card would help, but that's gotta wait until the new desktop. Whenever that is.
