Thanks for your reply, Kigen. My post didn't get lost in a sea of "how to comment out" this time.
You may wish to consider adding some of the CVARS I'm checking (for DOD:S):
default_fov 90 // changes fov if allowed
host_framerate 0 // speed hack
host_sleep 0 // lag like hell with high numbers
mat_drawwater 1
mat_fullbright 0 // 1 = no darkness, 2 = grey
mat_slopescaledepthbias_normal 0 // oldschool wallhack, pretty ugly in DOD:S
I've already seen 3 in one day with mat_fullbright 1. They had no other cvar reported.
edit: These were
false positives caused by no lighting in the map.
