Question / Help Dropped Frames During Recording

[ObsidianObelisk17]

Hello, recently I've been experiencing OBS Studio dropping frames while I'm recording video. Some games I can record without dropped frames, while some don't seem to want to record at my full framerate. Since I can record at full framerates in some games, I would assume it is a setting I changed in OBS or something with drivers. Frame drops even occur when I'm previewing in OBS without recording. My computers specs surpass what would be required to record at the settings I use, and the hard drive I record to can write up to around 300 megabytes a second.
I am running a Ryzen 7 1800X at 4Ghz with plenty of power and SOC voltage. I have two 1080s SLI'd, overclocked and stable. I use a GTX 1050 Ti at stock settings for encoding. All temperatures are fine.
I use multiple monitors, and have tried running the monitor with OBS on it on my primary and my encoding GPU, with the same results.
I do have the latest Nvidia drivers, but do not have the newest Windows 10 update (the one that adds GPU graphs to task manager, not sure if it's full release or just beta/preview though).
I attached a log of OBS when I launched OBS, recorded fast motion in a game for around 30 seconds, and stopped recording.
Any help is appreciated. Thanks

Remove the 1050ti physcially and set obs back to using the 1080 as the nvenc encoder card.

I tried that, and the frames still dropped.
However, I changed the settings under Advanced Video, resetting the Color Format and the YUV Color Space from their current settings, RGB and 709, to their default values, NV12 and 601, and kept YUV Color Range at Full, and that seemed to stop the frame drops for now. I will reinstall my 1050 Ti and see if the settings I changed fixed it, and update with any new findings.
P.S. Your quote mentions not saving to mp4s. What would you recommend instead? The only reason I use mp4 is they are a generally universal format and understood by most video editing software. I tried mkv before but Adobe Premiere doesn't understand mkv natively, and mov required QuickTime, which isn't updated for Windows anymore.

OBS Studio supports remuxing from flv/mkv to mp4 for the case of editing software like Premiere.

Excuse the late reply, New Years eve and then I forgot to check back. Which would you recommend for recording at the best quality with disregard to the file size? I know YouTube and other services have bitrate limits that wouldn't even scratch the surface of the quality lossless records at (lossless for me reaches about 500 mbps), but I would rather have something high quality, then have it compressed later. With the initial recording, Premiere compiling, then YouTube's processing, that's a lot of compression that could, lets say, make the video look like a quadtree aneurysm. Film grain and motion blur can really mess with compression, especially in a video that's been compressed several times.
