I love this game and have been trying to get better, but once I hit around 150-200 especially if I use the cell splitter or the lightning discs my computer just shits itself and I no joke drop to around 5 frames a second until I just cant keep myself alive. I am running an old PC, like 970 GTX old, wondering if anyone else runs into this or if my comp is just too old for the game lol. Thanks!

UPDATE:

If I only use the pistol and do not select the cell splitter or the thunderlink, I am able to get to around 6:30 minutes and around 250 kills before the wave that spawns basically stops my frame rate completely. The big monster that spawns from the cell splitter seems to have a huge impact on system resources as well as the later waves. I am actually upgrading my system this week so I will update this on how it affects nighmare's stability on the client side.

Same thing happens to me and I'm running a newer gaming PC with an RTX 2070, so it must just be the game itself doing that.
