Hey Everyone!…. do my PC can run Sims 3 smoothly having these specs: Intel Celeron D (3.4 GHZ), 2 GB DDR2 PC 667 RAM, 512 MB DDR2 PowerColor X1650 Pro AGP (3.0 Pixel Shader) and a Service Pack 2 Windows….. actually that are the specs that I’ve only known from my PC. Thanks in Advance.
you might have a bit of the problem with your CPU. Celeron’s dont perform that well. Your video card is above minimum but you might need to lower down the graphical setting for playable framerates
