I don't really care about frame rate in a sim game, you'll be fine, the buttons still respond. That's not the issue here..

Got to Minmus and managed to still land after discovering the crossfeed bug had used up all the fuel in the other stages. This didn't matter, once I clicked the EVA button the whole landing craft did a backflip onto its head. I reloaded the save I made when I landed and while I was able to get out the second time all the fuel in the lander had disappeared.

Early Access is supposed to be playable enough for people to want to play long enough to provide you with the feedback you need to improve the game, this by contrast is almost complete pandemonium.

I recommend waiting about a year or two for it to be playable, because what I saw a glimpse of is still promising.

edit/update:
NOPE this game is abandoned, just go get KSP1 and mod it instead
