Why are not there any well known and good browser 3d games?

CSGO, Minecraft, R6 - all in hype. Why not with browser? Maybe there was Agario - but that's not a 3D game. Are browsers too weak to render that? Or are there other problems? Sorry I was bored and got me with this question.

Flash games do not have nearly as much potential as games from an engine, browser games just can't have the necessary performance

OK. Does FlashGames mean the Adobe Flash Addon? You can do it with your own engine

Most web games these days are written in Html5 itself because it is realtiv performant, there are also relatively nice 3d shooter. Nevertheless, nothing compared to eg Battlefield V etc.

In addition, almost no one would be willing to spend a webgame money.
