(the priviliges is required for some cross process communication, not directly for the sharing)
maan this is busted, it’s like microsoft doesn’t want people to use it. anyway i’ll definitely go deeper into this stuff next month probably. i have an application for windows where the user interface and the output are 2 separate processes. if i could find out how to use this feature in wddm the gui wouldn’t have to do the same image processing again for the previews (shared memory was even slower) and that could solve some performance problems.
