Make PhotoStudio use less real time to generate a photo at low FPS

It now takes 9 frames to take a photo. When framerate is low it takes even more than a second.

The only solution I see is making the photostudio either track the time it is using per frame and do more work up to a limit or make it detect lower FPS to do more work per frame. Otherwise the PhotoStudio will cause lag spikes and destroy frame time consistency which is about the worst thing it could do.

If #3625 is done with a background thread approach this will be solved as well. But if the game is already struggling with FPS adding more CPU load might reduce the FPS even further.

CaptureImage and Save takes a little longer. (I'm running LoadScene and InstanceScene sync)

Scene load will take potentially a lot of time if the scene is one that has not been loaded before because the scene load needs to load up any resources the scene has (if the resources have not been loaded already).
