I implemented hot reloading in my game (based on the odin hot reloading article by Karl Zylinski, and the Handmade Hero).
Turns out it's also trivial to hot reload all the shaders, which is handy when tweaking the post-processing shaders etc.
And also the new RAD Debugger can handle hot reloaded dlls, unlike some other debuggers which lock them. It still has some issues, but at least it works
