I recently bought Burnout Paradise: The Ultimate Box, and while playing, it is sometimes quite laggy. I know my processor is weak, but I don't know what is causing it. I forgot what graphics card I have, It is a recent Nvidia. I have an AMD Athlon 64 Processor 3500+ with 2.19 GHz. I also have 1 Gig of RAM. The game recommends a 2.8 Processor and 1 Gig of RAM minimum. I was wondering if anybody knows what's wrong. I think it's the processor, But I don't know.
