Have you heard anything about your support case?
Disabling 3d acceleration makes Citrix Workspace usable for me too, so this is great and thank you Roman57, but latency is not great. I'm assuming this is due to no 3d acceleration. So I'd also be very interested if Parallels has responded and whether there's a fix likely. For reference Citrix for Mac has much better latency for me, but I much prefer to run under parallels for 2 reasons: 1) I can connect a Windows keyboard direct to the VM which gives me all the right shortcuts on my Citrix session and 2) I use 3 monitors and parallels allows me to switch spaces (between Mac and Windows/Parallels) for each monitor independently whereas Citrix for Mac switches all 3 monitors which I find much less flexible.
Have run into this in the past a number of times. Best way to fix is to disable Hardware Acceleration in the Citrix Workspace App:
From the article - set this in the Registry:
Registry Path : HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Citrix\ICA Client\Graphics Engine
If anyone, that affected by this issue, write to the support - they will increase the severity of the case and (I believe) the issue will be resolved much sooner.
Wondering if anyone has any updates on this issue? I still get the problem on both Intel and Apple Silicon Macs - have to disable 3d acceleration to make my Citrix session usable, but that introduces an annoying latency. I have raised with Parallels support twice, but nothing helpful back yet - have just raised again with them.
Parallels support got back to me with "we have been approached by several customers with this issue and disabling 3D acceleration is the only way to improve the performance of a Citrix application." Disappointing, and I'll just have to live with it.
Same issue here despite the solutions on this thread. They keep telling me to reset my network settings and put it into bridged mode which hasn't helped.
FIX: I'm running MacOs Monterey, Parallels with Windows 11. Citrix workspace
Prior to fix Citrix environment had lots of latency issues. Really unusable.
1. Within Windows 11, Download DirectX SDK, and install
2. Run DirectX Control Panel
3. Choose Direct3D 10x/11
4. Under Scope: Edit List ...
5. Add C:\Program Files (x86)\Citrix\ICA Client\Receiver\Receiver.exe
6. Choose Direct3D 9
7. Choose Software Only
8. Hit OK and reboot.
9. Now my Citrix is running well under the Windows 11 Parallels environment.
I hope that helps!!
We really appreciate your contribution. Thanks.
This is the fix we've all been waiting for. You're a hero. Accuro EMR on Citrix and Dragon Medical One working just as well as booting into BootCamp now with Parallels. You should get paid for this...
This should work better than the originally discussed method that disables 3d rendering for the VM entirely. Instead, this method would only disable 3D rendering for the Citrix app.
However, DirectX SDK is deprecated in Windows 11. Here's a modern way:
(Unsure if required) Download and install Windows SDK https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/
Within Windows 11, download Graphics Tools
System Settings > Apps > Add an optional feature (View features) > Graphics Tools
Start > Run > dxcpl.exe
Scope > "Edit List..." and add:
"C:\program files (x86)\citrix\ica client\receiver\" (Yes, may as well add the whole directory. This requires the "\" at the end)
"C:\program files (x86)\citrix\ica client\"
Set Feature level limit: 11_1 (Parallels 18 does not support DirectX 12)
Check "Force WARP" (This forces software rendering)
I haven't had much luck either way, but I figured as long as I was trying it out, I would share the steps I took.
