You must have Ati 9XXX or Nvidia 5XXX series or better , if you have then select il2setup.exe and change this , use opengl, have stencil buffer on, and a 32bit resolution , than open conf.ini with notepad and put this under render_opengl section set hardwareshaders=1 and water=2 for ati or water =3 or 4 for nvidia
This now calls "Perfect mod" it will drain more from your PC but graphic is much better.
CAUTION! Please be sure to back up the original config file! I tried it, it looks DAMN sexy, but it is to laggy to run on maps with a lot of planes. have the original file on hand to swap out when you dont want to use it.
