Massive 30% Regression with official AMD Drivers vs Microsoft stock on Vegas

Question asked by amd_64 on Sep 21, 2019

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.
