Mesh rendered much slower with geometry at close position?

Haha thank you @srzerbetto
I was just trying to replace instancing with common mesh due to performance issue.
In my case large number of geometry (quads) are placed in a single mesh with one single draw call, so instancing does not help (actually worse haha).

Mesh with thin instance slower than with full vertices?

Hello all, I am trying to imporve the speed Gaussian Splatting, where I find the usage of thin instance a problem. To simplify the problem, I tried to render certain number of quads with or without thin instance. If I put geometry info of these quads whithin a single mesh, the fps is 60. Draw 2 million quads with single mesh While using thin instance will have much lower fps around 15. Draw 2 million quads with thin instance I wonder if there is any problem with my usages? I thought thin …
