Yes I do, I have done every trick in the book, changing the client files, going from high to low and no shadows. In the regular environment I can do 50-60FPS but with some action jumps to 40 or so. In the Fleet I have 12FPS and just about the same in PvP. I know a lot of this is a issue with the game itself as many people have these issues even with a good pc.
Either way I could use the CPU upgrade as you seen above and I just got 64bit OS so I can finally upgrade ram as well. Just seemed like a good time to do it.
