stuttering and slomo on ps4

[tenim]

hi,

i have played the long dark on my ps4 and the first 10? hours i´run ok. but now (episonde 2, "have you fixed my rifle"), the framerate is very low. walking speed is probably half of the normal walking speed in the game. also some micro suttering (walk normal, than slow, than normal again). this is in indoor areas the same as in outdoor areas.

please fix this issue.
