Witcher 2 seems to be having issues with the FPS. Its not running very smoothly and it has almost every setting in low.

Here are some of my Specs

Processor
Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz, 2667 Mhz, 2 Core(s),
2 Logical Processor(s)

RAM
4.00 GB

Video Card
HD 4870

Is there a way to make it run better?
