Tips to get higher FPS?

[ForeverBlue]

I recently got Project Reality to finally work, but now my FPS is really low (10-15 FPS) in urban maps with a lot of objects like Fallujah, Gaza, ect, but a runnable FPS between 30-60 with maps like Falklands.

I have tried lowering my resolution, going full screen, using lowest graphic settings and off whenever I can. Is there anything more that I can do besides upgrading?

I do have a awfully low spec PC but I'm able to run Battlefield 2 at all lowest res and graphics with 60 FPS.

you Need a pc than runs battlefield 3 or better because Project reality uses more resources than bf3

The achilles heel is your CPU and since the game engine only can utilize one core your options are limited (faster core equals higher fps, unless your gpu is a potato) apart from playing with lower settings and on low populated servers.
