What is the most important component in my computer?

The Videocard! Twinmotion runs a game engine, so it is most important that you have a good gaming card. Take one with at least 4 Gb RAM and if possible use one with an nVidia chip.

Oh and download and try the trial to see if your system suffices!

You can also check the list with benchmarks on and search for a card with a rating of least 6000.
