Well, you know… we think that 2k vs 4k is basically half because of numbering, but its really not.
There’s 4 2k images inside a 4k image…
And 16 within an 8k one.
Having half the savings is really just wishful thinking. Its more like 3/4ths worth of savings when you scale down to the next avaliable option.
And yea, its 100% valid… as always, projects need to be benched/tested for performance considerations…
