I am using bevy 0.10.0 on arch Linux. I have a low end computer but still i don't see why a simple rectangle takes 30% of my CPU on htop.

probably it's that you need to limit the fps so it isn't drawing the rectangle thousands of times every second

i tried limiting with FixedTime but still the same issue

are you running with optimization enabled?

#

Also, by default, v-sync is enabled and should limit fps

#

FixedTimeStep is for game logic, not rendering and shouldn't impact rendering

Yeah thanks, I tried now to compile with Performance Optimizations and its lowered it to about 4%
