I’m using disk shape for both gameplay elements(opaque) and visual indicators(translucent). The disk plane mesh adds more polycount and the disk masked material adds more shader cost. Which one should I use performance-wise? They don’t come in large quantity and size varies but sometimes it occupies a large portion of screen.
Edit: Misunderstood the question
Generally speaking a masked quad will be the best option but my guess is neither will make any meaningful difference in performance. These are things you usually only need to be concerned about when you have a large number of instances or on very limited hardware (mobile VR, for example)
The exception to this is if the mesh is Nanite, because masked materials are horrendously slow with Nanite. In that case you should use geometry.
If you’re very concerned you should create a test case and measure both options with the profiler
