First off, he's played this long and still uses 3.20? I've never seen a nocheat say from him, and he doesnt come back on !versions with an r1q2 or apr client.
r1q2 can be a pain in the ass for the occasional player used to 3.20. I recently was forced to use anticheat again and still get a rubberband effect (with cl_async off and anticheat, doesnt do it without anticheat) when i play. so its not for everyone when you have to mess with it to get it to work similarly to 3.20!
