pmove->frametime = pmove->cmd.msec * 0.001;

to know what is the value of frametime ("delta time") each frame
would need to know whats the value of cmd.msec

someone knows which is the value?

I assume frametime its a constant value but may vary due to frame drops I guess?
And cmd.msec could vary due to network speed?
