GL-RM1PE KVM and Mouse Latency

KVM
1

Video and keyboard latency is excellent connecting to my Mac Studio, but mouse latency experiences some lag when moving the mouse.

My Mac Studio has a Bluetooth-enabled mouse (Logitech Anywhere 3S for Mac) that is using the Mac’s built-in Bluetooth. I’m not sure if the host mouse has anything to do with it, but putting it out there in case it does. The mouse lag from connecting clients is experienced with a Windows 11 and MacBook Air using their built-in trackpads and using a Bluetooth connected mouse.

I’m connecting via Google Chrome (v149.0.7827.103) over 10G LAN with the Mac Studio connecting at 10G, MacBook Air hardwired at 2.5G, and the Dell Precision 7770 Windows 11 laptop hardwired at 1G. Both connecting clients experience the lag.

My current configuration:

Video: normal mode, lowest latency, lossless (have used all settings), WebRTC, best picture quality (have used adaptive without any change). Remote device settings: speaker/microphone off. Keyboard is on, bad link mode/show virtual keyboard/swap commands off. Mouse is on, show local cursor is off, mouse jiggle off, scroll rate 5, scroll direction vertical invert, mouse mode absolute (relative doesn’t work).

I’m on v1.9.1 release 1.

Is there anything that can be done to improve the latency? It seems weird that video and keyboard are fine, but the mouse isn’t. Turning the mouse/keyboard off on the host device doesn’t change anything.

Thanks for any help anyone can provide!

We will significantly reduce latency when using the client or accessing via glkvm.com in version 1.10. To achieve the lowest latency possible with the current version, you must directly access your device's IP address for control or use a VPN like tailcsale or something.

I’m directly accessing it. Anyway I can get early access to 1.10?

nope.

The more I look into this, the more I wonder if this is a macOS issue. My Mac is running macOS 27 dev beta 1. With the HDMI connected, the mouse lag appears both with the KVM and when connecting via RustDesk. When I disconnect the HDMI, it goes away. I’m thinking there is an issue with macOS 27 and two monitors with remote connections. I do not see the issue locally on the serving computer. Disconnecting the USB-C keyboard/mouse cable from the KVM and powering down the KVM does not have an effect. It seems to occur simply having the HDMI plugged in.

I filed a Feedback Assistant report with Apple: FB23152500
