Nvidia Game Recorder with MSFS

[Bill A 68]

Hi all, those that use the Nvidia recorder to record their flights, how are you getting a smooth play back when playing back your flight as an MP4? I sim runs very smooth with frames unlocked. But in the playback when the takeoff roll starts things start to get a bit choppy and jumpy even though during the recording it was nice an smooth. I have tried 30 frames and its horrible, 60 frames is not too bad during flight and taxi but landing and takeoff its a different story.  I even cranked the bitrate to max but that made no difference.

How are other Youtubers getting such smooth playback when recording their flights? I have tried locking frames, unlocking frames, G-Sync on/ off...and more

My monitor is running at 240mz, I do have a side monitor and that is running at 60mz but I just use that monitor for Navigraph, Vpilot, PacX

no way, you mean 240 Hz, Mhz would be 1.000 Hz 😊

make sure to either temporarily disable any anti virus or at least exclude the recording directory. make sure the recording drive has plenty free space, otherwise write speeds go down considerably. might want to test/benchmark raw write speed. might help to have MSFS and recording directory on separate NVME's

LOL, yes 240Hz

MHz would actually be 1.000.000 Hz...

I use the game bar and it's smooth. I haven't even installed GeForce Experience since a long time. Maybe give it a try...

correct, I meant: 1 MHz = 1.000 KHz

You will find your head hurts running with all those Hz

tried the game bar recorder and still not very smooth as the actual sim was ran

Game bar only does 1080P recording and creates big files, (don't know what the bitrate is).

GeForce recording is far superior. I did a recording at 4K60 and it was pretty smooth. I recorded on to a different drive and the bitrate was set to 50Mbps.

I've had the best luck running GFE video record at max bitrate and at 8K after reading someone's argument that somehow that works best.  But it's not perfect, not as perfect as MSFS is and no wonder since MSFS pretty much maxing out many resources at least here.  The best method is to use a video capture card in a second machine I'm told and then you can get best possible video.

Here's one I did that is quite smooth, and to do it had to load a plane easy to process, AS CRJ:

I've been using Nvidia Shadowplay to record flights for a long time, and here's my (layman's) takes:

I guess the foundation for a smooth recording is basically an exact match between the framerate in the sim and the rate at which it is recorded. Nvidia Shadowplay allows to record with 60 fps or 30 fps. As long as MSFS puts out exactly 30 or 60 fps, your recording will be smooth. So my settings within MSFS are VSync On with 1/2 refresh rate on my 60 Hz monitor in order to get a smooth and stable 30 Hz framerate within the sim, and recording with 30 fps. But regardless of a smooth ingame performance, Shadowplay recordings will be stuttery, especially in complex situations like takeoffs and landings.

Looking at different framerate counters I think what happens is that despite a smooth look and feel, the framerate in the sim isn't exactly 30 fps, it is somewhere between 25 and 35 fps. And that shows in the recordings. And I also noticed that while flying I tend to concentrate on the centre of the screen, while stutters are more noticeable in the corners - and that's where you have time to look in recordings.

I get better results with OBS Studio, but sometimes the recordings are stuttery as well. I'm not yet finished with the more enhanced settings there, but I think as long as the hardware isn't capable of producing a rock solid framreate to match the recording rate in every situation, compromises have to be made.

Thank you. I think you gave nailed it on what's going on.

It's dark so you may not see it as well but not stuttery here--look at the taxiway lines and lights as the plane is turning on to the runway threshold--very smooth and in DX12 mode in MSFS, no stuttering.  I'm pretty sure this was done at a frame rate of 33 as well so the capture rate and frame rate were not the same.  I think the reason this came out so good was a function of using a plane much easier to process as the Aerosoft CRJs are relative to PMDG/FBW/WT

I think what is most important is stabilty within the range of the capturing framerate. Maybe your real framerate was more in the range of 31 to 33 due to the less demanding CRJ while in a more complex aircraft it might fluctuate from 27 to 35 fps. There is certainly some threshold where stutters become noticeable. I have smooth footage with the Kodiak as well as stuttery results, and the capturing software for sure isnˋt aware of the airplane we are using.

@Bill A If you plan on a lot of screen recording I would suggest a dedicated program that will give you zero issues with numerous features beyond screen capture. ACTION screen recorder on sale now for $20 - lifetime license! Never had a problem and extremely user friendly.
