I have a
3090 GPU
3900X @ 4.7Ghz CPU
64GB ram @ 3200
Gen 4 NVME SSD for system and the same for game storage

I'm recording footage on the a regular HDD dedicated for OBS.

As you can see in the video, all is going well enough, until I record many movements in the aircraft, then it starts to be really choppy.
the thing is, while in-game. I don't notice these lags. It's totally smooth. Just the recording is that garbage.

But I do record on the highest settings possible.

I tried recording on an external Crucial X6 NVME SSD connected vie USB C, but it's much much worse. this behavior is the same in any setting and resolution for some reason.

I used to use a separate gaming laptop I got from work, to record in max settings with the NVI plug-in. It worked really well. but alas, I don't have that resource now.

any recommendation to tweak the settings a bit to be able to record a flawless 4k experience?

P.S. - GAME CAPTURE feature if busted for the better part of a year, so I have to record the whole display.

thanks guys :-)
 
Post a logfile from a streaming or recording session at least 30 seconds in length. We really need one to perform accurate troubleshooting. Why it requests one whenever a new thread is being opened in the Support section. :) There's a ton of things that can cause issues like this, and the log should tell us what in this case.
 
Use the Quality, not Max Quality preset. MQ requires the use of CUDA cores and can cause encoding overloads even on systems that should have no problems otherwise. Psychovisual Tuning and Lookahead can do it as well, but you already have those disabled.

Aside from games that refuse to whitelist OBS' Game Capture hook (Des2ny, CSGO, a couple others), Game Capture usually 'breaks' when you're running a conflicting piece of software like Rivatuner, MSI Afterburner, and so on. Shader packs can do it too; anything that hooks the game executable. Here's a list of common problem applications:

Known Conflicts

OBS Studio - Free and open source software for live streaming and screen recording - obsproject/obs-studio
obsproject.com obsproject.com

Of course it's vastly preferred to use a Game Capture instead whenever possible. Be aware that a Monitor Capture in the same scene as a Game or Window Capture (even disabled/not-visible!) can cause major performance issues. If a MC is required, put it in its own scene with NO GC/WCs to minimize the chances.
 
Do not record using CBR. It is the WORST method, and is only used for livestreaming due to the infrastructure requiring it. Record using CQP.

Neither of the new logfiles show a recording session, so much of the pertinent information does not show. The second logfile indicates that the system is claiming to have TWO 3090s installed. If you do, be aware that SLI causes significant performance issues with OBS due to how they handle shared memory space. It's strongly advised to only use single-GPU systems if possible (SLI-required configurations are one of the few times that 2PC setups are still relevant at this point).

The logfile DOES indicate that you have HAGS enabled, which can cause performance issues. Here's instructions on how to switch that off: https://obsproject.com/wiki/How-to-disable-Windows-10-Hardware-GPU-Scheduler
The freezing would be a system issue. OBS may be triggering it (since real-time video encoding is a computationally intensive task), but the underlying system would be the root cause.
 
so OBS in general seems to be eating 20%-25% of my FPS. And that's when all settings are optimized. On to of being very buggy. I just can't seem to win in this. and since the game DCS is vital on visual clarity and FPS, OBS is just a no-go for me. NVIDIA SHADW PLAY eats just 3-5 FPS (how the hell do they do that?) and with 130mbits at 4K 60 FPS.
It is much less configurable, but it WORKS. So goodbye OBS
 
I have visited huge number of website in my life. But I can not find this types of post. I think this is the best post that you have sent for us. and look at my site
