Premiere Pro lagging with H.264

Hello everyone, I've found a problem, in which Premiere Pro (preview) lags and skips around when attempting to edit H.264 directly, and I was told to just re-encode to something like utvideo, which works, but I'm working with around 100GB of H.264, and re-encoding this is going to take many times as much space and time. So, something that I've noticed is that Aftereffects seems to preview the video fine, however, Premiere Pro seems to lag, and not like the files at all, unless they are re-encoded, then they work flawlessly.
My system specs are:
AMD Ryzen 7 1800x @ 3.8GHz,
32GB DDR4 @ 2113MHz
GTX 1080 GPU

Which should be fine for editing, correct? So, I'm not quite sure if this can be solved, as i previously edited H.264 directly with my i7 system, which I no-longer have.
Any ideas or suggestions would be greatly appreciated.

Edit: I have tried enabling/disabling CUDA and yes, PP and AE both have access to 28GB's of system memory. Also, CPU utilization is extremely low >2%. I'm working with 20Mbps H.264 in 1080P.
