I Optimised My Game Engine Up to 12000 FPS [video]

[mpwoz]

This was a really cool deep dive into various optimizations that apply specifically to voxel-based games.

I especially enjoyed how the author packed progressively more information into the bits of a single integer using some clever tricks, and it stayed approachable the whole time even for those who don’t do a lot of low level bitwise optimizations in their day to day (me)

High engine FPS is also super important for stress testing the potential servers and/or doing some machine learning inside the game.

he should rather invent a screen with a higher refresh rate

That’s not going to improve rendering speed. FPS here is used to gauge how quickly the scene is being sent to the GPU.

For a given rendering quality, faster is always better, even if your display can’t show frames that fast. In such a case you render as fast as the display can go and no faster, to save energy and allow the computer or your game to handle other tasks within the frame time.

I mean it's voxels so

Could have also not used those

None of these things are secrets or even hard to learn on one’s own.

I am not a developer (not a real one, anyway) and I am definitely not a game developer but I wrote a ton of 3D stuff for work and learned all of these optimization techniques along the way.

Once one learns the basics of how data is sent to GPUs, these techniques all become obvious, though some are much more difficult when you don’t restrict yourself to a world built with axis-aligned cubes.

They don’t have to be. This is just an absolutely great educational video, not a phd paper.

So things are obvious to those who spent N amount of time learning about things. Got it.

You have developed pieces of software. You are a real developer.
