VERY LOW GPU USAGE, HIGH CPU USAGE

When using Vegas Pro 16, my PC (i7-7700k + GTX 1070 with Windows 10 Pro) intensively uses my CPU. My CPU usage is always 80 - 100% when editing or rendering whilst my GPU sits at 0 - 15% usage. This is causing editing to be slow and rendering times to be much longer than it should be (EVEN WHEN RENDERING WITH THE MAGIX NV ENCODER).

I have done everything. Absolutely everything to try fixing this problem. I've looked online and visited nearly every forum page relating to this issue and still haven't found any solution that works. I decided to make my own thread as my last hope.

I have enabled 'Allow legacy GPU rendering'
I have selected my GeForce GTX 1070 in Options > Preferences > Video
I have switched between both the Game Ready and Studio Ready drivers.
I have selected Vegas Pro 16 in Windows Settings > Display > Graphics Settings and set the 'High Performance' setting
I have installed the Nvidia CUDA Toolkit software
I have selected Vegas Pro 16 in 'Manage 3D settings' within Nvidia Control Panel (changed CUDA - GPU and OpenGL rendering GPU setting)

My last guess is that a file which allows GPU Acceleration to work is missing from my PC or corrupted.

*NOTE:
WHEN I CHECK GPU IN SONY AVC/MVC TEMPLATE > SYSTEM IT SAYS 'NO GPU AVAILABLE'.
Maybe the software doesn't even detect my GPU. However, NVIDIA GPU Activity shows 'vegas160.exe' under 'Applications running on this GPU'

If anyone reads this and can think of another possible solution, please respond with it. I am losing hope.

I'd reinstall the HD 630 and set decoding in file I/O to auto. The Intel will do some hardware decoding as it supports more file types. For the render itself, did you try the advice above? Voukoder works well within Vegas.

Why you render times may depend on source media, Fx used, system power and render settings. If you're doing something like noise reduction or stabilization expect it to take forever. If you're going 4K to 1080p it should go faster than real time (1 min. footage to 1 min. render). If you use NVENC codecs you may go quite a bit faster than that.

If you want to see if your system is working normally for Vegas, download a standard benchmark project and compare your scores against ours: https://www.vegascreativesoftware.info/us/forum/benchmarking-results-continued--118503/?page=1
