    Odd behavior...
    Works fine on newer devices, but trying to do some performance tuning on an older Samsung Tab A 8.0 (SMT-350), which has 1.5GB RAM.

    I created a brand new scene. Added a Quad with scale 1,1,1. Published and runs on the device, rock solid 60FPS. If I resize the Quad to a larger size, like 20,20,1 and publish to the device, the framerate drops to 40 - 45 FPS (22 ms).

    I put a more complex model in the scene and it runs at 60 FPS until I add the quad back in so I know it's not something scene specific. So far it looks like moving from the standard shader has some impact...looking for advice. Thanks.

    Hi!
    What shader are you using? Is the scaled quad covering more screen area than the non-scaled one?
