AMD CCC has a "preferred color depth" option that has BPC (Bits Per Channel) values of 8 and 10 and 12. I've set it to the least BPC in order to try to increase fps rendering. (I suspect the screen is 8 BPC) because there is no information about this on the manufacturer's website.).
What are the benefits of having it set higher than what the screen can show?
Maybe for example shaders have better data so they can shade better?
