Stuttering and frame dropping in recorded video

I used to cap the game at 60 FPS and record at 60 FPS in OBS, but I experienced stuttering or frame drops around the 2nd or 3rd minute. After some research, I found out that the monitor refresh rate has an effect. My monitor’s refresh rate is 180.0066139996326 Hz, so I divided that number by 3, which resulted in 60.00220466654419. Then I searched for fractions that equal this number and found that 326592/5443 gives 60.00220466654419. I entered 326592 as the numerator and 5443 as the denominator in OBS, and in RTSS I capped the game at 60.002204 FPS. With this setup, the stuttering or frame drops now occur at around the 23rd minute.

Is there any way to completely get rid of the frame drops or stuttering in the recorded video? Note that while recording, the game runs very smoothly, resource usage does not exceed 50%, and I am recording on an SSD.

I also tried recording with ShadowPlay — I capped the game to 60 FPS using RTSS and set the bitrate to 50 Mbps, and there was no stuttering or frame drops at all in the recorded video.

Note: I also tried locking the monitor to 120 Hz and 60 Hz, but that didn’t solve the issue.
