Major Lag When Hitting 150+ Rad

I get a huge lag when I hit 150+ Rads, Im running the game normally with no lag at all and fps isnt shuttering. Just wanted to see if anyone else has this.

Same with me. I only get a lag spike when I reach 500 rads.That’s when the Radiation starts. :confused:

Not a bug, it’s a feature. Side effect of the rads.
