Grass texture performance question

Hi @ll,
i use for performancetesting a 1x79px “picture”, to texture my grassmesh and stretch it along the mesh.
Result is looking ok, but makes that sense to optimize performance?
Texture: Very tiny 1x79px, hard to see.

The result, looking ok with 394 Tris.

Makes that sense?

Texture resolution doesn’t matter that much, you’ll want to make larger clumps of grass, here’s a good guide. https://forums.unrealengine.com/showthread.php?30586-My-funky-(and-not-so-funky)-grass-shader&p=122424&viewfull=1#post122424
