Does this mean that the Upscaled Research Time doesn't affect the AI?
Does this mean that the Upscaled Production Cost option also only applies to the human players?
Everyone are affected by these options, since essentially there are four subsets of GameSpeed defines - one without options, other with upscaled construction, other with upscaled research and last one with both upscaled options being on.
Unless something in DLL was done so AI ignores those increases from upscaled production costs...
