Question / Help VERY annoying frame drops

[osu assassin]

So in the game that I play, it all will run smoothly, 200+ fps on average, until... I start recording. Sometimes the game will be rendered unplayable, leading the recording to have choppy frames sometimes. Also, what are the best settings if I want to record and I use an Nvidia GeForce GTX 1060? (Sorry if this isn't enough info, I'm EXTREMELY new to this.) At 2:05, the frame rate will suddenly drop, and then rise. (For this video at least.) I am not sure if it's an issue with the game or my settings. I went back into OBS one time when the frames dropped, and for a split second I saw something in the bottom left corner that I thought said something about Encoder Overload...

This version of Windows has a broken feature you can't turn off that negatively impacts OBS performance.

21:49:28.396: OBS 22.0.2 (64-bit, windows)

Current version of OBS is 23.2.1.

21:49:38.651: [NVENC encoder: 'recording_h264'] Failed to open NVENC codec: Invalid argument

Suggest to use simple output mode and an appropriate preset. The above error seems to indicate a misconfiguration that is causing the NVENC encoder to throw an error.

21:59:19.361: Output 'simple_file_output': Number of lagged frames due to rendering lag/stalls: 4102 (12.3%)

Rendering lag caused by GPU overload. This problem may be related to the problem with Game Mode, which is the broken Windows feature I mentioned earlier. If updating does not completely address the issue, look here:
