Hi,

This is my first time posting. I've installed the Sims 3 and there's a major problem with the graphics. I'm running a quad core AMD Phenom 9100c with 8 gigs of RAM. I recently installed a brand new Sapphire Radeon HD 4830 with the latest drivers (along with a 585 watt power supply). I've tried running the game on its lowest settings to no avail.

In desperation, I tried playing the game using the onboard graphics (ATI Radeon HD 3200) and while the graphics work fine, the game runs significantly slower.

My non-EA games (most recently MLB2K9) work great with my 4830, so I don't think the video card is defective.

I've attached a screenshot. Any help would be greatly appreciated.

All though what i;m about to say doesn't seem to bother my video card because it doesn't fall under it and still works, the sims 3 read me files say these are supported video cards of which the 4830 isn't on it

Otherwise, have you installed the current driver?

If the 4850 works there's no reason the 4830 wouldn't. I would check temps and update drivers.
