Got a new computer with high specs and recording in low fps and recording is stuttering.

So recently I got a new computer as my last one was getting pretty old and wasn't able to run things as fast as I'd want to, it would also lag quite a bit whilst recording with obs studio and one time my encoder overloaded and I almost lost all my footage. So I've been trying out obs studio on my computer and it is still having problems with the recording stuttering, it's not as bad as it was on my old computer but this computer is brand new and it shouldn't be having the stuttering problem at all, so I don't know what I'm doing wrong but I know it can't be my computer as it's very fast with everything else.
If you need any of my specs, just let me know which ones as I'm not sure which ones to post.
Also the game I'm recording is lego star wars: tcs on the xbox 360 at 30 fps.

Pls can someone help, my computer should be able to run games smoothly at 1080p 60fps but it’s stuttering while recording at 30fps and I have no idea why, I’ve tried turning up the process priority, I’ve tried different rate control but nothing is working

Run OBS as Admin
Make sure all your Audio is set to the same sample rate
Diable Hardware-accelerated GPU Scheduler https://obsproject.com/wiki/How-to-disable-Windows-10-Hardware-GPU-Scheduler

If you installed OBS in C then Instead of saving your recording on C save it in D and if it doesn't work then disable " look - ahead " and " psycho visual tuning "

Okay that seems to have fixed the problem thank you, I'll come back to this thread if I have any more issues.

Okay so I recorded again and it stuttered but only for a couple seconds near the start of the recording, is that normal?

Okay so I'm still having the issue, I'll try disabling look ahead and psycho visual tuning but I don't get why my CPU or GPU are struggling at all? They should be able to handle recording 30fps without stuttering so I've gotta assume something else is messing with my recording but I've got no clue what it could be, I feel like I didn't have this issue on my old computer either, it more just laggy on my old one so it's gotta be something in my obs settings or pc settings that's messing with it.

My sample rate I used before was 48,000 and my issue recordings were 44,100 so I'm gonna try 48,000 again and see if that helps

Yes, set your OBS sample rate back to 48 kHz. Change the NVENC Preset from Max Quality to Quality and uncheck the boxes for look ahead and psycho visual tuning. All three of these use additional GPU.

I just saw another thread of a guy having a very similar problem to me and his problem was fixed by recording straight to the ssd instead of hdd so I’m going to try that also.

Yes, that should help It's best to record to a drive that isn't the OS drive or where OBS and its assets are stored Best to have a drive just for recordings and one that has a write speed higher than your recording bitrate

Correct, typical 7200 rpm HDD have 180 IOPS (input/output operations per second) and a sustained throughput of 80->200 MB/s
IOPS in SSDs are orders of magnitude higher (easily thousands, and much higher)
vs current SATA SSDs that can saturate a SATA3 connection at around 550MB/s
vs a consumer NVME SSD than do 2,000-7,000MB/s

With all that said, recording with OBS to a HDD with a bitrate well under the sustained throughput is fine, AS LONG AS the HDD IS NOT in use for anything else that would cause contention (and AV s/w not trying to scan recording as being written, etc). so relatively easy to do, if you understand managing a computer. That is, throughput is unlikely to have been your issue, but rather multiple I/O streams contending to seek head access which can drop that throughput number to next to nothing. An example of what can cause I/O problems on a HDD include not having enough RAM, and OS using SWAP space.
OR a SSD provides massive overhead that largely negates having to worry/think/account for disk I/O in this scenario ;^)
