Surface split crashes my PC

Hi,
I’m trying to use this definition (which i have successfully used before in a smaller surface) on a large surface. However, everytime I try to enable Surface split (in a red circle in the definition) it crashes my PC. Even when I disable all the following components.

Is there anyway to make this definition lighter or is it my computer just not enough?

thank you
m.
