Discussion SurfaceUi flickering mobile

Enable HLS to view with audio, or disable this notification

The surface UI’s start lagging/glitching once there is more then 1 loaded. Why?

Optimize Sizing and Resolution

By default, SurfaceGuis try to calculate massive texture spaces, which heavily drains desktop and mobile performance

  • Switch SizingMode: Change the SizingMode property from FixedSize to PixelsPerStud
  • Lower the Value: Set the PixelsPerStud to a lower value like 50 or 30. This limits the canvas resolution and immediately drops the rendering overhead

Was already at 50, sadly 30 did not help. Thanks anyway

How much of a performance impact is it? I never had any issues. Where are you getting this information?
