Vela! A new desktop environment made to use just Vulkan 1.4, expecting to be faster than Plasma* and made with wlroots, but using a custom renderer. It has focus on fractional scaling, sharpness and usability. Take a look at https://velade.org

*currently building a benchmark suite, reaching approx. 40% less ram usage, 40% faster input lag, less cpu usage in some activities, and faster responsiveness during high cpu usage (from other tasks)
