Tinypilot KVM - delay introduced on heavier applications

So during the start of the session KVM is fast and all with almost all applications
but when we start accesing heavier applications like Visual Studio with a big project loaded onto it, the original laptop switches to and from the Visual studio window instantaneously, but the remote user sees a delay(2~4 sec) on that during switching the window

Is that something the later 4GB RAM version can fix. please let me know.
I have a need for atleast 2 other tinypilots
