I’m finally putting my hands on Unreal Engine, and Game Dev in general, and I noticed Unreal Engine by default sets the screen size to 1920x1080, and I’m a bit confused about this.
If the player has a 2K or 4K monitor and sets the resolution to their native ratio, will Unreal just Stretch the original one to that? Or the game must be designed for 4K and UE will handle resizing it to the ones with lesser pixels?
Also, if the HUD is to be created in 4K, and we suppose UE will resize it to a FHD screen, will this affect the processing time and result in a slower frame rate? Let alone if the GPU isn’t high end, then how could it render 4K then resize it, and still make it playable?
I just need some clarification how to handle this to continue with the right HUD dimensions. I appreciate any input that can help get me on my feet on this.
