So, my computer specs are: ATI Radeon HD5770, AMD Athlon 64 X2 Dual core, 4GB of DDR2 RAM, Windows 7 Ultimate. I think those should be enough to run The Sims 3 at least on medium settings without any lag. But it isn't like that in my situation. With the lowest settings Sims 3 fps drops to 30 and below while moving the camera in live play mode. That problem is only in the live play mode, but in the build & buy mode the game runs smooth. I do not understand what is wrong. Other games will run on ultra settings without any lag and fps drops, eg DiRT 2 I really need help. P.S I do not have any custom content. And confusing is the fact that with the highest settings game will run as good as with the lowest setting: fps drops to 30 and below in live play mode when moving camera. So changing setting to lowest does nothing.. Please help me.
Forgot to mention my cpu is Amd Athlon 64 x2 5200b 2,70Ghz
