    Hi! I found solution. Environment: parallels 16.1, windows 10 x32, Citrix workstation app. I had strange lags in Citrix. I realized that the lags are due to the video. If I disabled the video card in the system settings, then citrix started to work better. After I try disable h\w acceleration in regedit, but it didn't`t help. After I install Direct X SDK (I use DXSDK_Jun10.exe). Start - Microsoft DirectX SDK (June 2010) - DirectX Control Panel - tab Direct3D 9 - enable "Software Only".
    It worked fine! (Also it helped on VM Fusion)

    Hi AndrejS2,
    can you explain a little more regarding "I realized that the lags are due to the video. If I disabled the video card in the system settings" ?
    Do you mean the video settings on the mac, parallels, windows or cirtix?

    Thanks :)

    Thank you for posting a solution.
    Disabling video HW acceleration fixed two problems for me:
    • Unreadable text in Citrix due to black boxes appearing and disappearing anywhere in the Windows session.
    • Sluggishness, everything was VERY slow.
    Hoping for a fix in the next version of Parallels, maybe a switch in the VM settings to be able to turn off and on HW acceleration without having to install 1GB of developer tools.

    Where can I download Microsoft DirectX SDK (June 2010)? I can't find it on Microsoft's website.

    The solution for me was to install the Citrix Workspace App. I recommend it to anyone who has a similar problem. It is only necessary that your programs are compatible with this solution.

    Another solution - works for me on Parallels Desktop 16 + BigSur
    1. Turn off VM.
    2. Open terminal window and find out VM ID:
    prlctl list --all
    You will find something like
    UUID STATUS IP_ADDR NAME
    {69e7e93c-db19-46b4-bdca-a844651aed06} stopped - Red Hat Enterprise Linux
    {cd66c0b7-4e4e-41ca-969b-577df7413ea9} stopped - Windows 10
    3. Turn off 3d acceleration
    prlctl set <UUID> --3d-accelerate=off
    In my example:
    prlctl set cd66c0b7-4e4e-41ca-969b-577df7413ea9 --3d-accelerate=off
    4. Start VM and check.

    This is funny because I experienced this issue while taking Epic training and was about to post about it when I found this thread

    Success for me as well. Best way to ask Parallels and/or Citrix to investigate and resolve...?

    This command dont work with Standard edition
    "The command is available only in Parallels Desktop for Mac Pro or Business Edition"
    Looks like customers support just does not exist, as i tried to ask support for workaround with all possible ways.
    Also cant install dx sdk on new arm windows, is there any other way to turn off 3d accelerate or ask for refund?

    Try to edit configuration file manually:

    1. Open VM file in Finder with "Show Package Content"
    2. Edit config.pvs file.
    3. You should disable 3d acc.
    Here is the part of my file for VM with disabled 3d acc:
    <Video dyn_lists="" VideoMemorySize_patch="1">
    <Enabled>1</Enabled>
    <Type>0</Type>
    <VideoMemorySize>0</VideoMemorySize>
    <EnableDirectXShaders>1</EnableDirectXShaders>
    <ScreenResolutions dyn_lists="ScreenResolution 0 DynamicResolution 0">
    <Enabled>0</Enabled>
    </ScreenResolutions>
    <Enable3DAcceleration>0</Enable3DAcceleration>
    <EnableVSync>1</EnableVSync>
    <MaxDisplays>0</MaxDisplays>
    <EnableHiResDrawing>1</EnableHiResDrawing>
    <UseHiResInGuest>1</UseHiResInGuest>
    <HostScaleFactor>2</HostScaleFactor>
    <NativeScalingInGuest>0</NativeScalingInGuest>
    <ApertureOnlyCapable>1</ApertureOnlyCapable>
    </Video>

    Also, FYI I have created a case to support (#2959378). Unfortunately support team unable to provide JIRA ID for me - so it is impossible to track, when the issue will be fixed.
    Also, no ETA had been provided.

    Workaround if you have error installing DX SDK on m1:
    Uninstall all Microsoft Visual C++
    Try to run DX SDK installer, it could fail again, go to installation folder C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\system\uninstall and run vc10redist_x86.
    Try to install again

    I just wanted to take a moment to thank you for this posting. I was really struggling with Citrix on a Parallels try-out. The app was so unresponsive that it was effectively unusable. This made it workable, and quite responsive. Thank you!!
