I haven't noticed any fps drops either, and that's coming from the person with what is, most likely, the worst pc out of anyone playing this game
And yeah the overheating isn't new, I've done everything I can to combat the overheating for years. Unfortunaly my laptop is just so old that most likely, the heat makes some components swell slightly. Which makes them disconnect for a little bit, which then crashes/turns off my computer
The overheating isn't really the problem, the fact that this thing is 10 years old is :p
