Got some screenshots on Low, Medium, and High - all DX10. There was no discernible difference between High and Very High, or between IS Gauss and CGauss, and I can't attach more than 10 anyway. In order of appearance, because I'm too lazy to rename all the files:
(C)Gauss LOW
(C)Gauss MED
(C)Gauss HIGH
HGauss LOW
HGauss MED
HGauss HIGH
Lt. Gauss LOW
Lt. Gauss MED
Lt. Gauss HIGH
