Unstable FPS. I ask for the patch

only in custom stories.

for instance, you open the door and find yourself in a new large location. This location is loading. Fps falls to 30.  I run on this location for a while and fps rises again to 60. Then again falls. It feels like the game engine can't use 8 gigabytes of memory. and also 2 gigabytes of video memory. The game engine can handle only small locations of the original game. But I can't prove it. I m not Programmer.

I know for sure that the rain lowers very much fps, I do not know why it happens...
