    I'm playing a game, and for it to perform well it requires dedicated video memory. Is there a way to set up the VM to report some amount of the memory as dedicated video memory?
    Currently it reports all memory as shared and so the game has issues.

    Any ideas on this?
    I tried changing the HardwareInformation.MemorySize in the registry but unfortunately it does nothing :(

    Hello McAllen and thank you for your reply. I understand it might be inefficient to dedicate memory specifically to graphics.
    However some older applications require memory to be reported as dedicated to function properly. Modern solutions like for example DXVK allow for setting the amount of VRAM that will be reported to the application as dedicated. It is a fictitious number, that does not affect how the system allocates the memory but allows to run said application successfully.
    Do you think something like this is possible with parallels? Perhaps there is a way to request this feature, it should be easy enough to implement?
