Question: winSPMBT in Windows8

Yeah the blast radius option ("R" key) just shows white circles when shells are landing and smaller yellow circles where shrapnel hits. It slows down the bombardment considerably. It also shows the circles for machine gun fire and AT-guns etc... I never use it personaly. I guess it is just a graphical representation of how the game engine works for those really into that stuff.
