Why Am I Not Receiving Delta-V Calculations? in Technical Support (PC, unmodded installs) Posted July 30 I usually use mods, but I've removed them all when this problem arose. Therefore I've put this into the unmodded section. No matter what part combo or fuel type, I cannot get any info in the editor or in-flight. it simply says 0 meters/s and when I click on it to get the more detailed info like TWR, it simply does not display any data within the box. Please help with this as it is making the game almost unplayable for me.
