Yeah as I stated in the update disclaimer I'm working hard on performance improvement. Which graphical setting are you using? Did you disabled the light effect?
also, the level within the hospital, once you are caught also does not have this problem
however sometimes loading a save (probably on the 5th time I loaded a save in this level) in that level resulted in a state where the save would load me under the map, and turning the game off and loading, would not save me. so a way back into that level, if you have to use spawn point, would be appreciated.
