I am currently using Xshell to work on Linux server from my windows laptop and I like its UI a lot. However, I am using the free version which means I can't produce display like plots for visualizing data. Is there any other free software similar to Xshell but allows me to see display (e.g., -X)?

I also have VirtualBox to run Ubuntu but running it usually caused significant drop in frame rate which is why I avoid using it. But if there is a way to remove the lag, this will suffice too. Thanks!
