sprites with gradients / gaussian blur

[Mike018]

I'm wondering if you have a 30x30 solid square compared with a 30x30 square with a gradient or a gaussian blur applied to it, will that be extra processing power to move & animate it? From my understanding, once the sprite atlas is loaded, only the size matters, is that correct?

It should make no difference as the block of memory is the same block of memory.  However, in practise the results may vary - so instead benchmarks should be run, bottlenecks evaluated and optimized.  For example in some circumstances the format of the bitmap, the device used, the inputs to the lower level rendering methods etc can have dramatic effects on the throughput.

Yep, I agree, benchmarks are the only way to go.

I'd have thought image contents makes no discernible difference unless it has transparent or semi-transparent sections.
