I know this can be a stupid question. Of course, each game has a different structure, and the more optimized it is, the better. However, the answer is not known until all functions are developed and compared, so I wonder what experienced people think. I'm worried whether this is too much of a "premature optimisation" My target platform is a high-end PC console, not mobile. Do UI optimization issues below have a big impact on PC console games? I don't know if these issues are necessary tips for only low-spec devices such as mobile..or not - Divide dynamic ui canvas and static ui canvas - enable/disable only canvas components - improper use of Sprite/Image/Raw Image - Do not use LayoutGroup (like vertical group) etc.. Especially, I've seen a lot of stories about do not use layout groups. It's horrible to imagine working with only anchors and pivots for multi-resolution without using layout groups. Do these issues show significant performance differences in PC games? Is it important enough to actually feel it(Critical Frame Drop)?
