Utilize GPU while editing?

Hi all.

Recently I've been editing roughly 12 minutes of footage (down from 2 hours) and I have gotten to the point where both the preview and the entire application itself is running terribly slow. I cant run the preview above ~5fps and editing is almost impossible at times.
I checked task manager while the software was lagging out and I noticed that my CPU usage was peaking at 100% and my GPU was sitting comfortably at 2%. I was wondering if there was a way to utilize the GPU while actually editing the video, before rendering it, or anything i can do to increase performance while previewing.

Here's what I have tried:
-Checked that GPU accelaration of video processing was selected in Setting>Preferences>Video
-Increased dynamic RAM preview max by ~50MB (I have read that it is troublesome to change that for some reason)
-Increased process priority of Vegas in task manager
-Restarted my PC and software when it gets slower
-Moved all my project media to my SSD

Im sure if I could utilize my GPU I wouldn't have a problem

My PC specs:
Ryzen 5 1500x
GTX 1050ti
8GB DDR4 RAM
150GB SSD (on which Vegas is installed)

Thoughts?

Depends on your used Vegas version.

Using Vegas Pro 15 right now

There are links to and a lot of other info on your preview problem, which is quite common. Not matching the VP project properties to the media is a common cause of preview playback issues.

In VPro 15 you have only one option if your files are pretty heavy (more than HD AVC or HEVC)by the use of proxies, but in version 17 there are more options as decoding with help of your GPU

Surely theres a way to change the decoder in 15 (like to H.264)
What do you mean by using proxies?

That isn't what they are talking about. You're thinking codec, not decoder. H264 is a codec. Vegas 17 introduced GPU decoding capabilities, which, if you have intel quicksync or an Nvidia GPU, you can use your GPU to decode the video frames (if using H264 or HEVC video sources) so your CPU doesn't have to. This can speed things up a good bit when using those video types as sources.

Ah right, excuse my ignorance.
I guess the only way would be to upgrade to 17^ or to use proxies for now^^

Thank you
