Rendering speed : What consumes more ?

by LMD » Post

Title says it all :
- one big triangle
- or two, which are way smaller

Code: Select all

b - big triangle
s - small triangle
bbbbbbbbbbbbbbbbbb
s                s
Which one will(most likely) render faster ?
I am asking this because I am questioning myself if I should merge the two triangles, as the space between them would be inside the model, and therefore not viewable, to increase rendering speed ?

Less faces is always better than more faces, no matter what the size. So whichever has less faces should be used.

Ultimately it depends. There's a certain amount of black magic involved. On better machines, up to a certain number of tris it's more about the number of calls to the GPU you make - less is better. So rendering 1000 tris in a single call will be better than 100 in 10. But graphics isn't my area, so take what I say in a pinch of salt. You can't reduce draw calls from a mod as you can't modify the engine, so you can only reduce tris
