I have viewed both demos, the one that stars and assaasin posted.
@ assasin tick 2986 on your demo he's lagging. Atleast from your view, but that tick is equal to tick 3500 in the sourceTV demo and in the sourceTV demo he's smooth and isn't autotracing at all.

tick 3261 on your demo he's skipping around, in the SourceTV demo it's tick 3800 - 3900 and it's completely smooth and has no snapping involved it was completely fluid movement.
tick 11325 is equal to tick 12k on the sourceTV demo and during that whole time it was very fluid movement. He didn't snap and he wasn't tracing at all.

this is proof that your demo is lagging/skipping around and although it personal demos are sometimes nice to have, but they are subject to your latency, interp, A.K.A. your connection to the server and your FPS how fast your computer can process the information.
SourceTV is the solution to that and is the only way to rule out all of those variables. In the SourceTV demo he's not hacking


I would vote NO
