 @ae9c8437 > in 4 those problems are fixed.

As I know - no it is not fixed - every mesh still compile own shaders on first view on camera.

Only single difference in Godot 4 - shaders are in SPIR-V format so its about 5-10x times faster compiling, so maybe you have "fast CPU" and not noticing that it still lag, but for complex large shaders - there still lags and you do need some short loading. 

 @ae9c8437 Prove - I did that for every web-experiment:

https://danilw.itch.io/godot-graphic-demo-3d?password=demo

https://danilw.itch.io/particle-game-demo - has lag on pressing right click when right bar is full - once lag - because I forgot to put this particles to loading process

https://danilw.itch.io/particle-game-demo - you see loading that count shaders - press mouse left/right to see particles - no lags

https://danilw.itch.io/particle-effects-godot3 - long loading because lots of shaders, rotate camera to see lots of particles and move thru door
