Low clock speed on Vega 64

Discussion created by dustbag69 on Mar 21, 2019

Hi,

 

Since getting an Occulus Rift I have been disappointed with the performance I am getting with 45fps at best in VR titles. (Non-VR works great)

When I look at the Wattman performance while running VR titles it appears my Vega64 is only running core clock at approx. 900 which seems very slow. If I run a Non-VR title and check the performance in Wattman the core clock is >1500

It seems that for some reason in VR the graphics card is not running at full speed but in Non-VR it works perfectly.

 

Has anyone seen this before and got any suggestions how to fix?

 

Thank you
