CFS2 graphics "shimmer"

Hi:
I have CFS2. I also have an HP computer with standars vdeo card, etc. I'm not going to change the video card. On my computer, the planes in this game have an annoying rainbowlike "shimmer". It is very bothersome and not at all normal in appearance. I believe that the modelling for these planes as it involves displaying reflections off of surfaces is involved. I believe that there is a program that will fix this. Does anyone know where I could get a copy?
I have done a search and didn't find any answers.
Thanks
