       Show HN: Asdf Overlay - High performance in-game overlay library
       for Windows
        
       I am making a open source overlay library.  Game overlay is for
       rendering contents on top of game screen. Representative examples
       are Discord and Steam in-game overlay. They are complicated because
       it has to hook rendering part of a game.  Asdf overlay provides
       easy to use interfaces for rendering on top of game screen. I
       recognize game performance degradation due to overlay rendering, so
       GPU shared texture was used to avoid CPU framebuffer copy. Asdf
       Overlay is capable of rendering full screen overlay without
       noticeable performance loss.
