Skiiiiiphs! I require your assistance, please.
Ever since 1.3 came out, I've gotten some pretty heavy lagspikes on the lowest possible settings I can think of. I even have gore turned off. It'll fluctuate from 40ish FPS to as low as 15. And it'll just DROP, all of a sudden, so it's kinda hard to play. If it eased into being slow, that wouldn't be a problem, but spikes are hard to play around.
I know windows is preferable for gaming but I'm not going to purchase a new computer just to play a few games. I have a really crappy 4-5 year old PC that was purchased already used by my mother and I have a mac. The former can't run any game at more than ~20 fps with constant lag spikes and part of it is broken so it can barely charge when it's in use and its battery life is abysmal.
