Completely understandable. digging through my prefs some more I came across some additional items to check. These are in the ClientPrefs_Main.def which is in your individual character folder.
bool agfDiag = false
bool agfCompressVerts = true
bool agfConvertTest = false
bool convertIGBToAGF = false
bool aghConvertTest = false
bool updateAGHFiles = true
bool convertAGHDDS = true
bool ddsHighQuality = false
bool useAGH = true
int aghProxySize = 64
Good luck!
