I am having a major issue of choppy playback in Premiere Pro. I have upgraded my computer to:
RTX 3070, Ryzen 9 5900x, 32gb ram, 1tb samsung evo 970 and the problem has not become any better. I can smoothly playback video files in vlc however they are at <1 frame a second when playing back in premiere pro (even in the source monitor). I need this issue fixed as I edit videos for multiple clients and this has drastically slowed the video creation process. I have also tried the following to fix the issue with no success:
Clear cache, change installation path of premiere pro, reinstall premiere pro, update all drivers associated with my computer hardware, rollback all drivers mentioned previously, reinstalled windows, changed audio class, reinstalled audio drivers.
Creating proxies fixes the issue however it can take up to x8 the length of the video to create the proxy itself, and when I'm dealing with 3-6 hour videos it really adds up. The problem is not noticable at the start of the video and becomes worse over the duration.
If you find it of any use, here's the properties of one of the video files that causes this:

Frame rate mode : Variable < There's your problem. Premiere and other NLEs don't work well with variable frame rates. You can use Handbrake to convert your source to a constant frame rate before importing into Premiere. On another note, Premiere Pro 14.8 was just released, and it was mentioned that it might work better with variable frame rates.Maybe update to 14.8 and give it a shot. I haven't tried it myself, but just suggesting that it might solve your issue.
