Hello and thanks for any help. I'm trying to record Iracing in 3840x2160 base and output. When I'm watching the recording of it everything is smooth and fast until the camera swings around following a car. It has a small stutter that's driving me crazy. It seems like when the camera swings by fast its ok but around slower corners it stutters a bit. I've watched so many videos, tried so many settings, Even if I output to 1080 the same stutter is there. I have tried game mode on and off seems like there is no difference to me. I've tried changing game setting to minimum... same stutter. Maxed them out... same stutter. I am no expert but I have learned a lot since trying this for the last few days which is probably not a lot to you guys lol. while monitoring the recording... CPU 32%, GPU 63%, Memory 43%. Its such a small stutter but man what I would do to get rid of it. I hope there is something simple, Thanks for any help that will solve this issue if my pc can even do it but it seems as though im not close to maxing anything out and its so close. My log file while recording Iracing...
I am so close to what I am trying to achieve.

Switch off the psycho optimisations in encoder.
Try to use CQP instead of VBR.
But to summarize: You render 4Kp60 this way and have a good power on your machine! Otherwise your cpu and gpu usage (>60%) shows that its on its border doing this. Every camera swing in play then means _totally_ different content from frame to frame, rising encoding effort.
Even if you render down to 1080p the game-capture have to take over the whole content at 4K.
So try if play in lower resolution may help?

In the log, there is no mention of lagged or lost frames due to CPU or GPU overload, so you can disregard the above comment. You Laptop is able to handle 4k with nvenc well.
If this stutter is happening in different situations, it has probably some other, general cause. Explore the smoothness of videos created on your system with the help of this website: https://testufo.com/stutter#demo=smooth&foreground=ffffff&background=000000&pps=720
It's creating smooth animations you can test your recordings, and it explains different kind of lag and stutter situations well.

After watching the different demos it seems to be like the frame rate slowdown but its not as drastic as that demo.
So I made this video and its uploaded on YT @ 2160. Its still a little bit jittery to me even though my cpu and gpu still have head room recording it. Im just curious if there is a nvidia setting holding me down or is it just the way it is and get over it. I just want it to be smooth.
