Anyone noticed that when using qizmos (perhaps more than one hop) and trying to fire rl or lg, it sometimes shoots with sg? Its quite annoying. Any idea?

Sounds like packetloss. Show netgraph and see if there are red lines.

You can try increasing value of cl_c2sImpulseBackup (weapon switches are impulses).

Other option is Qizmo command .repeatc2s. You can find it in Qizmo menus also. It repeats every packet and therefore uses more bandwidth.

it seems i dont have pl, i've double checked it and there are no red peaks in netgraph, but im gonna try c2simpulsebackup, thx.
