VEGAS MAXES OUT MY CPU, BUT USES VERY LITTLE GPU AND RAM

I am an experienced audio producer / musician but a bit new to video edits.

I am trying to do some Multicam edits with 5-8 pieces of video shot on various iOS devices. ( audio has been removed and I have one stereo wave file in the project) total project is ~5 min long.

All the files for this project add up to ~ 2 GB ( I have 32 GB of RAM)

My playback is seriously lagging and I am trying to figure out why and how to fix.

I understand that vegas does not like codecs from iOS video, so I have run videos through HANDBRAKE first. I use the mp4 setting but they come out as H264- is this part of the problem? If so what should I change them to so that they still look as good as the originals?

When I open task manager my CPU is running between 96%-100% and my GPU is running at 3%

How do I get my GPU to share the load? It also says that VEGAS is using about 3300MB of RAM

Should VEGAS be taking advantage of more of my available RAM?

Is VEGAS maybe only using 1 CORE of the CPU ?

IF so how do I fix this?

Also I just learned about the idea of using proxy's and I am just made proxys for all the media in this project. This only offered a very marginal improvement - my play back is still very lagging. The marginal improvement is that VEGAS is only using 93% of my CPU and GPU usage went up to 7%

Also vegas is crashing often when doing this sort of work.

I am looking for some tech suggestions to make this all work as it should.

Here are my computer details :

Processor Intel(R) Core(TM) i7-9700 CPU @ 3.00GHz 3.00 GHz

nstalled RAM 32.0 GB

System type W 10 home - 64-bit operating system, x64-based processor

Video card chip - GeForce GTX 1660

Vegas Pro 17.0

In video preferences, GPU acceleration is set to OPTIMAL NVIDA Corportaion

GPU DRIVER version 27.21.14.5671

In the VEGAS FILE I/o Preferences "Enable hardware decoding for supported formats is checked

Hardware decoder to use says " Intel QSV"

Vegas is on my C drive SSD (1TB)

Video Files are on my E drive SSD (2TB)

I also have a 4 gb HDD and another 2tb SSD for music related sample libraries. All drives are internal to this PC tower (it is not a laptop) tower

@AaronL Alt+F1 just took a picture of your screen, if you open Geforce experience, there's a triangle at the top, Open in-game overlay, on the right is a cog wheel for settings, in there go to Recordings & you can choose the default folder for pics & video screen capture,

will do - in a bit - thanks for this, but to be clear - rendering does not seem to be the issue, it is when I am actively trying to do a multi-cam edit

@AaronL Yep, i'm only asking because if you choose the render with (NVENC) at the end, you should see your GPU working in Taskmanager, if it's still showing it doing very little,,,, it'll give you just another bit of info to help you narrow down the problem, ,,,🤷‍♂️

You can game on the Studio driver as it is the same as the gaming one, just released less frequently and better tested.

When you say proxy do you mean proxys made in Vegas or reencodes of the original files?

For performance please share a screenshot of windows performance monitor with the Intel iGPU selected (and have file io set to that rather than NVIDIA NVDEC).
