i don't think there's a difference between them in principle. at least from their descriptions and results.

[Woekele]

I think there is, otherwise 27 wouldn't have made it

[mitsubishi]

why? it isn't part of baseq3 i think. or wasn't early. but not sure.

in any way their descriptions are same or very similar.

shrooms still at it everday in every pub server with an xil tag.

They both do the same thing; modify timestamps on packets to make things appear they arrived later then they really did, except cl_timenudge affects your outgoing packets too.  This can be exploited to make you appear to warp if you turn it on and off quickly.  It can also be used to change how standard q3 projectiles like rockets behave, if you use negative values (it fastforwards them along their path a little bit.. very silly idea)

ut_timenudge doesn't affect your outgoing commands (so no benefit to negative values), but the server is notified about your "buffer" so that antilag can be matched up to compensate for your world-view delay.

so basically
cl_timenudge = sploits
ut_timenudge = no sploits

[mitsubishi]

so does 'ut' stand for 'unlagged timenudge'? :]

nah, unreal tourney.
