I posted in a thread of someone who played at 120hz, who also noticed that evenw ith 100+ fps at a 100Hz + monitor the game seemed to lag internally.
At first then I said I didn't notice, but now I do.
I've been playing other FPS games at 110hz and 90+FPS.
I notice even with 70+fps ALWAYS at 1440P NS2 lags a lot in game. It's just not smooth like other games are at the same FPS. and my monitor can display the frames at 110HZ.
I bet max already knows why we perceive this lag. An internal tick number likely at 30-60 ticks per second perhaps. Or perhaps some sort of player polling of position at 30ticks?.
I just want everyone to be aware of this, and hopefully there's an easy fix.

Just to check if we have this in common, but do you make use of Virtu MVP (graphics pipeline virtualizer)? I have a feeling that it has had negative side effects in several of the games I play.
It inherently comes with some input lag.
Also are you using any Vsync? Because it can cause input lag
Oh and are you using AFR or SFR? Because AFR also comes with inherent input lag. :-D
There are many things which cause input lag that are unrelated to ns2, so it's best to check all those out first before ruling ns2 as the culprit.
Dual GPU solutions are ripe with these issues, historically. So my first bet is you're using AFR. It was a cute trick used to gain significantly more fps in benchmarks.. But comes at the cost of input lag. Should investigate all those suggestions of mine though.
Hmm.. Need some way to quantify this. Perhaps frame latency ?
And record it with a high speed camera, because it would be the same as Youtube if it's not the case.
But yeah, you can have 100 FPS and have a game not fluid. And it can be separated from input lag.

SDK 09 suffers the same issue, compared to SDK 07, sdk 07 is smoother at lower framerates while sdk 09 requires almost twice as many frames to feel as smooth -- it's like 150 fps to 260 fps difference, however it might not be the entire SDK; could have just been something that went wrong during the games engine swap (not ns2)
