Resolution for Games
Hi, When using a High Definition Display, is there a way to render at exactly the target resolution on the physical screen? My understanding is that the default behavior is to render to a backing store with a resolution (in pixels) which can be twice the size of the logical resolution (in points). Then we let the OS handle the down-scaling to the actual target resolution on the screen. This is all nice for non-graphics intensive apps, but it means that my game will render at a higher resolution than needed, which seems like an obvious loss of performance. My expectation is that, for graphics intensive application such as games, we should be able to query and render to the final resolution on the display. Can it / should it be done? Thank you for your help :) FYI I did find a document which explains how to setup your CAMetalLayer to render at a custom resolution. I suspect that this may be what I have to do?
