I am running a 2015 15" Macbook Pro with an Intel Iris Pro 1536 MB, a 2.8ghz i7 and 16gb of ram.
Sometimes when I am playing this game, my battery will drain to 1% even though I have my laptop plugged in. A quick google search told me that if the laptop is drawing more than 85w worth of power, it will drain the battery at the same time.
While it is using integrated graphics, this is a very fancy new computer that shouldn't have any problem handling a 10 year old game. Even with most settings lowered, I am still running into problems with this.
Are there any settings that could potentially cause this to happen? I'm usually running it in windowed mode and have a few browser tabs and Spotify open, but that's the only potential conflict I can think of.
