Hello,

I have a question/problem with the Adobe Flash Player configuration-file called "mms.cfg".

I want to disable hardware-acceleration.

Therefore I have created a file "mms.cfg" with the following content:

Flash#1.png

As described here, I did open the website "https://helpx.adobe.com/flash-player.html#main_Find_Flash_Player_version_type_and_capabilities__Flas..._"

, scrolled down to the tree-example, right clicked it and opened the settings.

The dialog says, that hardware-acceleration is still being used!?

Have a look at the following screenshot:

Flash#2.png

It seems, that the configuration through "mms.cfg" doesn't work as expected.

How do I disable hardware-accelleration?

Thank you!

Tested on:

Windows 7 x64 – Flash Player 27 ActiveX

Server 2008r2 – Flash Player 27 ActiveX

Server 2016 – Build in Flash Player

The mms.cfg setting will override any preferences in the UI, but it does not update the UI.

No problem.  Out of curiosity, are you disabling hardware acceleration to work around a problem that we should be looking into?

Hello,

I am preparing the settings for Flash-Player running on our Citrix XenApp Terminal-Servers.

The Citrix XenApp-Hosts (Server 2008r2, Server 2016) are virtual machines running on Citrix XenServer Hypervisor.

The physical machines do not have any special GPU's or something like that.

As far as I know it is best practice to generally disable all hardware-acceleration features in this case.

Like mentioned here, otherwise a software emulated GPU is beeing used for things like this, which could result in a significant degradation of user experience.

You could give me a recommendation, if this is not true in case of Adobe Flash Player.

No, that makes a lot of sense.  Thanks!
