@icedquinn roblox runs like 30-60fps on my son's 10 year old PC. it does have two gtx 1050ti, but those cards were like $90 when i bought them new.
godot could use a lot of TLC with the optimization, based on my experiences with non h-games. Offhand, brotato was awful for a really long time, the latest patch actually made it run >60FPS.
there's others, but i am going to bed.
Good luck!
(p.s. beamNG runs like he's on a potato)
(also it's a 7350k which i bought for single core speed, rofl)
