The NoMachine Client and server enable a fast graphical work from CSC to your local computer. This makes using GUIs fluent. The idea is to connect to with the NoMachine client (free) installed at your computer (available for Win, Mac, Linux). Then from i.e. within Kajaani connect with ssh to the server where you want do your science e.g. run RStudio or VMD. The speedup vs. X11 (native or emulated) can be many fold, so you will experience substantial improvement. Note that with NoMachine you don't need X-emulators or X-term (in Linux).
