Massive 30% Regression with official AMD Drivers vs Microsoft stock on Vegas
I asked earlier but my question seems to have disappeared. I tested this with 100% reproducible results Specs CPU: 3900X GPU: RX580 RAM: 32GB OS versions tested Windows 10 - 1703 / 1903 Clean installs and no other apps running except Vegas and Task Manager
With the stock MS Driver CPU: 30% GPU: 100% Time to render 6:20
With the AMD drivers 19.3.2-Mar14 and 19.9.1-Sep4 CPU: 20% GPU: 80% Time to render 9:20
Almost 33% slower.
Another issue is with the stock driver Davinci Resolve won't open. So either I'm stuck with poor performance and can use Davinci and Vegas or I have good performance but can't use Davinci.
It's as if the official driver from AMD is throttling GPU. Temps are all low though and a well ventilated chassis with mostly NVMe / SSD's storage.
