NVIDIA Publishes DirectX 12 Tips for Developers

[Boomstick777]

Programming with DirectX 12 (and Vulkan, and Mantle) is a much different process than most developers are used to. The biggest change is how work is submit to the driver. Previously, engines would bind attributes to a graphics API and issue one of a handful of “draw” commands, which turns the current state of the API into a message. Drivers would play around with queuing them and manipulating them, to optimize how these orders are sent to the graphics device, but the game developer had no control over that.

NVIDIA has created a large list of things that developers should do, and others that they should not, to increase performance. Pretty much all of them apply equally, regardless of graphics vendor, but there are a few NVIDIA-specific comments, particularly the ones about NvAPI at the end and a few labeled notes in the “Root Signatures” category.

Between the lines,

Please optimize for our GPU's and don't use anything that would give AMD a boost

Dont's

Don’t rely on being able to allocate all GPU memory in one go

Depending on the underlying GPU architecture the memory may or may not be segmented

Hahaha, GTX 970

LOL, typical nVidia business practise then

When you're selling 8/10 cards then I guess you can!!!

Exactly it's a real shame, even when AMD have some decent hardware advantage. Nvidia own the market and can just ask developers to not use it
