DOPP can't be enabled

[ilwoonam75]

Dear.

I am currently testing dopp function with Radeon Pro WX 5100 card.

When I try to enable dopp with DOPPenable.exe. it says dopp can't be enabled.

For reference, with FirePro W600 and W4100, I successfully enabled dopp.

Hi ilwoonam75,

the current DOPPenable application only works for the FirePro GPUs.
We are working on a solution to unify DOPP enablement with an option in the Radeon Pro advanced settings but it is not available yet.

You can enable DOPP for Radeon Pro GPUs yourself though by setting a registry key:

• Open the Radeon Pro settings
• Navigate to System->Hardware
• Get the registry path from the "2D Driver File Path" field
• Set the registry key "KMD_EnableDesktopTexture" in that registry path to 1
• Reboot the system

Dear,
I successfully enabled DOPP function by changing registry key.
Thank you very much for your advice.

I have one more question,

I have two WX 5100 cards and two monitors in one system,
each monitor is connected to each WX 5100 card.

When I run DOPPEngine from this repository and what ever desktop I choose from the DOPPEngine (ex, I select Desktop 2), the effect is only applied to primary monitor, I mean desktop 1.

Dear
I realized that there is another repository about DOPP in GPUOpen.
I successfully enable DOPP with multi GPU environment with DOPPEngine from
https://github.com/GPUOpen-LibrariesAndSDKs/DOPPEngine.

Thank you again.
