Always wondered how some people managed to get so few transistors on their designs? Here's a new guide from one of the top HC players describing a detailed, systematic approach! A must-read for all people in search of advanced optimizations. steamcommunity.com/sharedfiles/...

This is a guide for more advanced pass transistor logic (PTL) with an example level. If you don't know what pass transistor logic is or if you haven't read my previous guide, then I highly recommend y

Adding a heatmap to see the render cost of each pixel is cool and very handy! I should get rid of those red-hot spots 🤔. I already have an idea for how to reduce the ray-travel cost in empty spaces. What optimization trick comes to your mind? #raymarching #indie #indiegamedev #render
