This can also, depending on the hardware, cause +performance problems due to constant resizing. This can be mitigated with the Padding property. +While resizing may cause problems on the GPU side, the content bounds calculation also takes time +on the CPU. If more inaccurate bounds are enough, Combine Bounds can be used to have less +calculations per object in the layer. The user has to balance the performance cost of the resize +to the performance gain of the lower texture size when evaluating the use of this feature. + */ |
