I'm glad I see some others that go to bashandslash.com instead of just me. I'm using this config also, but i've upped my resolution to 1024x768 and have capped my fps at 125. There are a few links if you look there under cod2 I believe that talks about com_maxfps, cl_maxpackets, snaps (the sweet spot) to help reduce ping and hit registration. Sometimes I have to turn my LodScaleRigid back down to 2 instead of 4 though because the server admin puts a check on that dvar.
See ya in-game
