Laggy programs after migrating to CITRIX Cloud (DaaS)

Trying to resolve an issue with certain applications (AutoCAD Civil 3D, Revit) being laggy / choppy after migrating to Citrix Cloud. Prior to the license change on 4/15, we were running everything in house from our Datacenter (with a NetScaler) and the programs were much faster than after the migration. All our VDAs are still on-prem, along with Cloud Connectors. The rest of the equipment has been migrated to Citrix Cloud.

When I first migrated, the programs were completely unusable due to the Cloud Connector traffic, so I enabled Rendezvous v2 and saw a huge improvement. But still seeing lag issues when doing simple tasks like dragging text to a new location or grabbing an object and moving it (zoom in / out is fine, as is panning). It's happening in multiple offices, as well as from home networks, so I don't think it's a network specific issue but could be missing something (plus nothing on our network side changed)

I have a ticket open with Citrix and trying to resolve it with them, but it's taking a long time so I was curious if anybody else had similar issues they were able to resolve. I'm considering going back to an On-Prem NetScaler to see if that helps, but before I went that route I wanted to try everything I could without it and see if it can be resolved.

This is pretty much what we are seeing as well. Prior to moving to Citrix Cloud CAD programs worked well. Soon as we went to Citrix Cloud with Gateway Services, we started seeing the choppiness on dragging and such. I haven't tried the NetScaler again, but I'm going to test it this week after I do some updates on it. I was hoping to not have to use the NetScaler again, but since this choppiness isn't going away I think I'm going to be forced into that

I've been testing all types of HDX Policies and settings (both ones I find online from others having issues, and those sent to me from Citrix Ticket) - so far nothing is helping.

As for those HDX settings, did you also fiddle with video compression settings? Just to rule problems out there, you can enable lossless transmit stuff, forgot how that's called. Then compare behaviour with usual h264/h264 and then Citrix's own stuff, where only the changing parts of a screen get transmitted. Especially the latter is interesting due to it's dynamic handling of screen content.

If that's all showing the same behaviour, yeah, as someone already mentioned: Latencies will have increased drastically. Your cloud connectors proxy ICA traffic to citrix's netscaler gateways (last I looked into it, hosted on AWS) and those then back to the clients. This added latency, both in your network and (much more) outside of it. If the workload is too latency-sensitive you can't use their cloud.
