I have city labels pinned on a top down strategy map that the player can pan around. I wrote a small if() statement that checks if a city label is in the camera frustum and sets Canvas Group alpha to 0 if it’s out of view. This saves about 500 draw calls on average but then I realized, I’m adding about 300 Update() checks (once for each label).
I realize draw calls are the heavier thing but by how much? Is it CPU vs GPU performance? Should I try to do more draw call reductions like this?
