RimWorld drops Unity for its own in-house engine, says your saves still work, so do most mods, and the whole thing runs twice as fast

Those are some 'wipe your glasses, rub your eyes, triple-check you did the maths right' numbers that RimWorld's new Waylith engine is spitting out, but it seems to be the real deal. Over on Reddit, players who are trying out the new engine are finding impressive results: "Stable 120 fps and 900 [ticks per second]. Normally I have at max speed 60/700ish," says TheLemonFox . "Impressive." Though they also report the new build is RAM-hungry: "it eats RAM like there is no tomorrow. 12-13 GB RAM directly at startup is… something."
