This seems to be quite an issue for me. When connecting to the remote desktop from my Win 11 laptop, dragging windows etc is super slow. Also the solution of setting the connection speed to Lan as suggested in #2136 doesn't help. However when I try the same with my Win 10 desktop, changing the setting to Lan results in a performance boost while having it set to WLAN gives similar results on both systems. It seems to me like the issue described by @metalefty could cause the symptoms I see.

metalefty · 2022-11-16T01:23:03Z

@TuNeXiZz Yes, the issue seems to be caused due to this.

@jsorg71 Jay, can we add Image RemotFX? I'm not very familiar with RemoteFX but as far as I read MS documentation, Image RemoteFX has little differences from (Video) RemoteFX. It will take a while until we implement GFX. I think some mitigation is needed.

Nexarian · 2022-11-28T01:02:56Z

@metalefty I can look into this. I'm guessing that most of what we already have makes this possible...

metalefty · 2023-07-17T06:17:51Z

After #2400, codec GUID is recorded on the log. The Win11 client sends only 2 codecs:

[2023-07-17T14:25:46.742+0900] [INFO ] xrdp_caps_process_codecs: NSCodec(CA8D1BB9-000F-154F-589F-AE2D1A87E2D6), codec id [1], properties len [3]
[2023-07-17T14:25:46.743+0900] [WARN ] xrdp_caps_process_codecs: unknown(2744CCD4-9D8A-4E74-803C-0ECBEEA19C54), codec id [5], properties len [49]

2744CCD4-9D8A-4E74-803C-0ECBEEA19C54 is for Image RemoteFX. So we need to implement Image RemoteFX capability to reinstate performance with Win11 client.

samikha · 2023-08-09T08:35:39Z

+1

Indeed, a Win10 client sends 3 codecs and the performance is good:

[INFO ] xrdp_caps_process_codecs: NSCodec(CA8D1BB9-000F-154F-589F-AE2D1A87E2D6), codec id [1], properties len [3]
[WARN ] xrdp_caps_process_codecs: unknown(2744CCD4-9D8A-4E74-803C-0ECBEEA19C54), codec id [5], properties len [49]
[INFO ] xrdp_caps_process_codecs: RemoteFX(76772F12-BD72-4463-AFB3-B73C9C6F7886), codec id [3], properties len [49]

But with Win11, only 2 are sent:

[INFO ] xrdp_caps_process_codecs: NSCodec(CA8D1BB9-000F-154F-589F-AE2D1A87E2D6), codec id [1], properties len [3]
[WARN ] xrdp_caps_process_codecs: unknown(2744CCD4-9D8A-4E74-803C-0ECBEEA19C54), codec id [5], properties len [49]

And no RFX is used which affects the performance

Nexarian · 2023-08-10T02:21:36Z

Try going to the settings described here: stascorp/rdpwrap#810

AVC444v2 wasn't working on my Windows 11 install until I went there as well. This is keyed for AVC444, but there are RemoteFX settings too.

metalefty · 2023-09-08T01:51:17Z

Started initial implementation: #2789

metalefty · 2023-09-19T09:07:09Z

As far as I read the specification [MS-RDPRFX] the difference between Image RemoteFX vs Video RemoteFX is:

The encoder must send theencode header message sequence before every encode data message sequence.
The encode header message sequence is then followed by an arbitrary number of encode data message sequences.

@jsorg71 What do you think?

So it is much easier to implement than GFX and easier to backport to v0.9.

metalefty · 2023-09-23T17:08:12Z

While working on this, I found an issue that seems to be a FreeRDP bug.

FrederickGeek8 · 2023-10-17T17:08:50Z

Thank you for working on this! This is important to my work because I spend much of it in RDP and the lag is awful. I downgraded to Windows 10 because of this problem. Thanks a lot Microsoft…

samikha · 2023-10-18T06:58:58Z

@metalefty
Thanks a lot for working on this too!

@FrederickGeek8 In the meantime on Windows 11, I'm using a wfreerdp.exe FreeRDP client downloaded from here:
https://ci.freerdp.com/job/freerdp-nightly-windows/

(linked to from https://github.com/FreeRDP/FreeRDP/wiki/PreBuilds)

The performance is not as good as Win10 client, but it's much better than the lag when using the Win11 client. Make sure you call wfreerdp.exe with /rfx

It's really WIP and not working yet.

I'm using this client: https://apps.microsoft.com/detail/9WZDNCRFJ3PS?hl=en-US&gl=US

It seems to perform better than Windows 11 mstsc.exe and wfreerdp

Note: MS does not develop that app anymore, but it's a good alternative while waiting for Image RemoteFX support

metalefty · 2023-12-14T08:12:03Z

Thank you guys for the information about other clients!

We're working on implementing another efficient codec compatible with Win11. Use other clients such as FreeRDP for the time being as a workaround.

metalefty · 2024-02-21T00:51:15Z

GFX support with multi-monitor support (including monitor hot plug/unplug) has been added (#2256 #2338 #2595 #2879 #2891 #2911 #2929 #2933 #2942). v0.10.0 will be released soon.

samikha · 2024-07-30T06:16:15Z

BTW, running the latest xrdp versions I seem to be getting RFX Pro codec (from xrdp.log):

xrdp_encoder_create: starting gfx rfx pro codec session

which gives good performance when using Microsoft Remote Desktop client

metalefty · 2024-07-30T06:23:21Z

Yes, we have switched to RFX Pro from classic RFX. This issue can be closed now.
