Well you can easily test this

In the nvidia control panel, select the "Desktop" menu at the very top and make sure that "Add 'Run with graphics processor' to Context Menu" is checked.

Then right click on the game exe or make a short-cut of it and select "Run with graphics processor ->" menu, and select "High-performance NVIDIA processor."

Graphically D:OS is most definitely VERY demanding as it has proper shadows, but you should get well above 30 fps even on a 540m
