    Basically a 1.5x to 2x performance boost for heavy, bursty CPU processing situations. Preventing big framerate dips in these "worst case scenarios."

    Starting with 4.5 dev 5, you can expect your Web games to run a little bit more smoothly, without having to do anything. Especially when things get chaotic (for your CPU). It isn’t a silver bullet for poorly optimized games, but it will help nonetheless. Also, note that it cannot do anything for GPU rendering bottlenecks.

    I love Godot! The 4.5 feature I'm most excited about is the inline color preview/picker in the code editor. The tiny color squares are soooo cute
