That is what I did, and then proceeded to install the drivers again.

I tried multiple versions of drivers ranging from 2016, 2018 and the latest 2020 ones

No effect, SVP still reported No acceleration for each one

I'm running Windows 10 Pro (Build 17763) and I have an AMD Ryzen 3 1200 Quadcore CPU and a GTX 1050 Ti GPU. SVP reports No acceleration when trying to pick GPU acceleration
All playback is slow and choppy so clearly the GPU is not being used at all.

I have already tried re-installing SVP and re-installing drivers, but this failed.
Any ideas?
