I understand the concept of "it's a word because people use it" - but what does it actually mean? No one can give a consistent defininition because it's nebulous jargon with no clear or specific meaning. Without fail, every single usage is obfuscating or otherwise hiding the intended meaning.

Check out this Unity blog post I just came across: "Achieve beautiful, scalable, and performant graphics with the Universal Render Pipeline"

What exactly are "performant graphics"? Does that mean high frame-rate? High-poly? Extremely vibrant colors? HDR? Can run on a 486 with software rendering?

It doesn't tell me anything, and is essentially "vocabulary clickbait" - it "sounds good", without really communicating anything. This is why I despise this word.
