Hi, I use Opengl/WinApi/C++ with Windows XP and i'm trying to do a transparent window. I've tried so far to use WS_EX_LAYERED style with my window and then set the transparency level with SetLayeredWindowAttributes function. It works, but the framerate is totally unacceptable. Could there be a bottleneck here that i haven't noticed or should i just take some other approach for transpacency?
