It isn't intended to be fast and doesn't implement any sophisticated video compression algorithms covering both performance and image quality aspects. Also, you don't need 4k60fps for a out-of-band terminal connection to fix some configurations.
Ah
I find VNC pretty responsive usually. You sure it’s not a network or load issue?
weird it works well lol
That's why I am asking cause I can't find the really issue, regarding my home internet it's pretty stable and good (goes upto 500 Mbps but it can depend yeah) , regarding servers even on best servers I always have same issues on vnc
The vest working vnc I found is on firebase studio which works without any bug, lag for me
You trying to do gaming or watch videos via vnc ? or just do some system maintenance. One is doable the other not so much IMHO
Try RDP, it can be better.
Might try RustDesk. Fast & Free
I guess you're using vnc from a web browser and not a client, in browsers yes they so laggy but I haven't seen any problem when using client
That might be true, I have never used a specific app for vnc , just directly from browser
VNC is request driven, which means framerate is latency bound inherently. Latency puts a cap on the speed that the client can request and receive updates from the server. (slows down the transaction rate)
Protocols such as NX, Moonlight, and others that stream encoded video don't have that constraint and are only capped by bandwidth.
EDIT: It should be responsive on LAN. Just less responsive as distance goes up for remote control over the Internet if you need it to be realtime. You have nearly unlimited bandwidth, so ---
If bandwidth doesn't matter, try something like Sunshine / Moonlight.
How about VNCviewer ?
Should apply to any client that uses VNC, though I know there's some variations of the protocol with third-party clients and servers that add encryption and other features that VNC lacks.. (Base VNC proto is very insecure and should usually be ran behind SSH or similar)
If you need to use VNC on a server, one solution is to host a local proxy with Apache Guacamole. https://guacamole.apache.org/
That allows you to run VNC on the server, get fast connectivity to the Guacamole relay (which is local, or on the same machine) -- then connect via Guac over the Internet, which is not latency sensitive.
