How do I fix laggy playback in Premiere Pro 2020

Question

I have been having this problem for a while now and I don't know how I might fix it. The video I'm recording is pretty long, high bitrate video, but my computer seems like it should be able to handle it. My problem is with any and all video playback as soon as I import it into my project. The playback is extremely laggy in the video preview as well as the timeline preview. Is there any way to fix this?

Important Specs:

CPU: i7 7700k
GPU: Nvidia GTX 1080
Ram: 16 GB
Video Storage: 500GB M.2 SSD

If you need any more information to understand my situation bettter let me know.

The footage came from OBS and it's a screen recording. It has the most optimal settings possible for recording. It also has 3 audio tracks.

screen recordings often have a variable frame rate which can be problematic in premiere

use mediainfo to determine whether your source is variable or constant frame rate

if it's variable use handbrake to convert to constant frame rate

and here's a tutorial on how to use handbrake

Followup on this topic. I have been tinkering with it for a while now and the problem shows up with high bitrate video. The bitrate of my video is 18158kbps and it is 1080p 60fps footage. I checked my task manager while editing and my cpu/gpu are fine, but my m.2 ssd is stuggling hard which makes sense for high bitrate video. I can't convert to a proxy because I have multiple audio tracks so I have to convert to apple pro res making the files 10x in size. After converting to proxy, I was able to edit just fine even though the files were massive, but I can't do that for every file or I'd be filling my storage with as little as two files. Has anyone found some other workaround for this?
