Question / Help How to record smooth 1440p60 with nvenc?

I've tried all kinds of different settings in OBS, but I always get video with duplicate frames (every 1/5 or so), which looks like stutters in playback.

When I record with shadowplay, I get perfectly smooth video with unique frames only. The only problem is that the highest quality/bitrate in shadowplay is pretty bad. (I still got duplicate frames in OBS when using the same shitty bitrate as in shadowplay.)

Anyone have any suggestions?

try 2 pass off and bframes 0
use the high performance preset

your cqp value is extremely high - I would assume high loss in quality with it?

I get good results with no bframes and no 2pass - like said - try it :)

I can capture a 2560x1600 @ 120 (!) fps video without duplicate frames with these settings with a GTX 1080

The biggest change to avoid the duplicated frames should be to change the preset. "Default" shouldn't be the default, really. Try High Performance (HP) and if that works, you might try pushing it up to High Quality (HQ).
