minecraft 1.12.1 isn't terribly unplayable on the 10 year old thinkpad
it stutters around, but whenever it's not, it manages to keep a rather responsive framerate
perhaps optifine can improve that even more
@squirrel that is pretty impressive...
@bea i'm super surprised at what this thing will run, i've been throwing plenty of stuff at it
youtube and netflix run perfectly
specs are 1.6ghz core 2 duo with 2gb ram, so for 2007 it was quite the powerhouse
it does however turn the thinkpad into a lovely and effective lap and hand warmer
