Zooming in Editor with Low Resolution Very Slow - Bug

Hi,

I appear to have a bug, just want to check with everyone first :wink:

I often create retro low resolution games, such as 320 x 180.

When you have a game resolution this small or smaller, when you try to zoom in with the mouse-wheel, it is extremely slow, moving in very tiny steps the larger the view becomes - it is tediously slow.

It seems that the zoom speed is based on how big your game resolution is - or something similar. The more you have to zoom into somthing, the slower it becomes.

If you have a 1080x1920 resolution game, then in is reasonably fast as you should expect. But you never would have to typically zoom in as much as you would with a low resolution game, so you probably don’t notice it.

You would expect to have a result the same whatever resolution the game is - the zoom should be the same speed.

Agreed, zooming gets perceptively “less” as you zoom in further and further.

I think technically the zoom factor is increasing the same amount, but since we’re already zoomed in so far the actual increase is felt less. (i.e going from 1x to 2x zoom is much more impactful than going from 50x to 51x zoom)

It would make more sense to me for the zoom to be exponentially/logarithmically the same, although I’m not sure on the math required for that.
