-Flowing transparent hair
-Water reflections, refractions, particles and physics
-Player physics effects
I honestly don't know why we have not seen riot do these things after years of development,
If we can rework everything why not the graphics engine so players with the processing brunt can turn on these effects.
8 years and were still just using really basic effects,
your game client has no excuse to be having frame drops.
Meanwhile @id Software
This is a rework of Doom 2
This is my friends engine in GZdoom that handles 100 enemies at a time...
