As far as I know, there are three factors that affect RDP:
First: Hardware configuration of the locally connected device (Windows 10 desktop version)
Second: Configuration of remote VPS
Third: Network delay
So the question is how to configure the hardware so that the local operation can be smooth without lag and the remote VPS can be operated smoothly:
First: How much CPU, memory, and storage space will you give to the local virtual machine?
Second: How much CPU, memory, storage space, and bandwidth should be provided for the remote vps?
Third: Because the vps that use the tor network are connected through the RDP tool, the characteristic of the tor network is that there are usually more exports in European countries such as the United States or Germany, so how to choose an offshore vps provider and how to choose the location of the machine to minimize network delays. According to my understanding, with less delay, the operation can be smooth.
Welcome experts to discuss
rdp lag comes mostly from latency jitter and packet loss, then from rdp display settings like resolution color depth and animations, and only after that from cpu or ram limits. for a smooth local vm avoid swapping and keep graphics modest, something like 2 to 4 vcpu and 4 to 8 gb ram with ssd storage is usually enough. on the vps you mainly need steady cpu and fast disk for whatever apps you run, often 2 to 4 vcpu and 4 to 8 gb ram plus stable bandwidth, and enabling modern rdp h264 helps a lot. if you route over tor it will add unavoidable latency and jitter, so pick a vps region close to you with good peering but don’t expect it to feel like a direct link.
