Why are my headphones buzzing whenever I run my game?

There's a certain cinematic quality to this story... perhaps so much so that if it were to be included in an actual movie it would be seen as "too over the top" (i.e. CSI-like)

The source is electrical noise, but the solution of isolating the audio chain from the computer's USB means that in the future you might not notice when you've introduced another GPU memory bandwidth hog into your rendering loop.

Good story, though.

These effects used to be much worse in the nineties, often even if you had a fancy sound card. Electrical noise is significantly reduced now.

> A picking texture is a very simple idea. As the name says, it’s used to handle picking in the game, when you click somewhere on the screen (e.g. to select an unit), I use this texture to know what you clicked on. Instead of colors, every object instance writes their EntityID to this texture. Then, when you click the mouse, you check what id is in the pixel under the mouse position.

Unrelated, but why? Querying a point in a basic quad tree takes microseconds, is there any benefit to overengineering a solved problem this way? What do you gain from this?
