Strange fps drop

[LawSyL]

So i downloaded blacklight retribution and i played it at low 130-140 and everything enabled + max 60-80 fps. The next day i turned on my pc and i got on low 30-50 fps? I have no idea how. The game runs on my nvidia GPU so no intergrated graphics crap Sombody can explain why? and how i can fix it? Tnx for the help!

GPU: 1: Intel HD graphics 4400 2: Nvidia Geforce 820M
RAM: 6GB
OS: Win 8.1 64bit

You managed to play Blacklight Retribution that well on that GPU? Consider yourself lucky that ever happened in the first place.

Yeah i know it is pretty crap. But how did i manage to restart my pc and play the game at 120 fps but then after 1 day it can't even get 60? i even recorded and got 80 fps average
