MSTSC is one of the rock-solid tools from Microsoft, and does better than almost everything else available on the market other than some PC over IP technologies specifically highly optimized for this use case. I've been programming with an ancient ThinkPad forever because I'm just remoting into a much more powerful machine.
And if it was actually software emulated, which I can't believe for a moment, though I admit I never checked (I just always assumed the window contents were transmitted via some kind of video encoder) - then I can't imagine that a text editor would be a problem.
The input latency might not be as good as you'd like.
Yeah input latency is annoyingly rough, not super bad but _just_ laggy enough to make it annoying to use.
Debating how much I want to change things, I can directly punch into my Linux machine but all my dev IDEs are on a VM for a long list of reasons, and I doubt Zed is going to run on my old ThinkPad if it struggles on software rendering, but we'll see.
