Honestly if I can top 15 FPS on medium settings, I'm chilling
Having played heavily modded KSP 1 for around 3 years now, I'll be glad to play a game that the devs at least tried to optimize.
To be clear, I'm not trying to put down the original devs, they did really well with what they had, but I don't think it's outlandish to say what they had was pretty garbage
