I am using Dgvoodoo and I am able to run REdBaron 3d in glide 1024x768......... but I can barely make out the planes in front of me ..they are very wavey looking and lot of flat murkey white sky. I have no problems with my joystick (Saitek EVO)or sounds issues etc Able to continue playing mission after mission without exiting etc

Any suggestions?

BTW when I modify with HASp(w/SP3) I donot have the glide option available.........

thanks in advance>
