It's fairly optimized with caching and only running at a low tick rate. And it only checks room type, whether there is a roof, and the share of floored tiles.

With tons of rooms eventually it could affect performance like anything tick based.

How is the overall performance? I tested it a bit and it looks fine but are there szenarios we should care about? Nice mod btw!

Nice, this will be a mainstay in my list for sure from the sound of it. Hope it blows up as a solid addition to really any run!

Thank you! Planning to roll out the flooring bonus to all room types soon including kitchens, workshops and laboratories.

nice little mod to make good bedrooms more worth it
