Question / Help 3960x + 2080TI - Skipped frames

[SnoringNinja]

Hopefully someone can shed some light on this, since I am a bit curious as to what I may have configured wrong for this system. When I am doing local recordings, using new Nvenc, 2080ti, I am getting skipped frames due to encoding lag. System specs below, and log attached.

Threadripper 3960x, stock speeds
GeForce 2080Ti, stock speeds

Unfortunately the log from the initial hour I was recording was lost when OBS crashed upon restart, so I've attached the next best log I could get which has the problem. Temperature wise, everything is fine, nothing would be throttling as far as I can tell, and this is a dedicated streaming machine. For the purpose of this log file, the game I was recording was Guild Wars 2 at 1920x1080.

I have also tried a scene collection that was just the game capture and nothing else and still had the same problem, but again, unfortunately, I don't have that log.

I appreciate any insight as to what the problem could be; thanks!

Turn of Psychovisual Tuning, and lower your quality down from "Max Quality". Both of these options (including Look Ahead) all use CUDA processing, which in your case is not given a high enough priority to meet frametime requirements.

I tried that (at least I think I set that correctly), but the issue is still there. New log attached.

I'll be honest, I'm not exactly sure what's going on -- this is a very similar situation to the problem in this thread. I'm curious to know -- was there a recent Nvidia driver update? It might be worthwhile trying an earlier WHQL version and seeing if the problem persists.

As an alternate route... is there any reason you're not using x264 encoding, considering you've got a 3960x?

Solely out of curiosity, to be quite honest. I do plan to stream using x264, but when I did the recordings and noticed this it piqued my curiosity and thus I wanted to try and figure out what was going on.

There was one recently, but I had noted this problem before that. I'll try downgrading to a different driver and seeing if that solves anything, but I'll also do one on the x264 side (which I should have likely done beforehand) just to make sure there are no issues there.
