Writing an efficient, modern renderer is truly an exercise of patience. You have a good idea? Hah, fuck you, GPUs don't support that. Okay but what if I try to use this advanced feature? Eh, probably not going to support exactly what you would like to do. Okay fuck it I'm gonna use the most obscure features possible. Congratulations, it doesn't work even on the niche hardware that supports that extension

If I sound jaded, ya better believe I f*cking am! I cannot wait for more graphics cards to support features like mesh shaders so we can finally compute shader all the things and do things the way we want to god dammit
