Is the  AmdPowerXpressRequestHighPerformance flag officially supported by the AMD drivers, and if so, where is it documented?

Question asked by on Aug 28, 2017

My team is developing software for the healthcare industry, and we need a way to prefer the AMD discrete GPU for some of our DirectX/OpenGL applications. I find references to the  AmdPowerXpressRequestHighPerformance variable that can be exported from the application. However, I am not able to find any official documentation on this flag.


Is the  AmdPowerXpressRequestHighPerformance variable officially supported by AMD drivers, and if so, are there any limitations that we should be aware of? Where can I find official documentation for this feature?
