OpenGL support and filters.

Leandro Jardim · 19 March 2012, 22:33

Does will take time to add support for OpenGL? Most people on the net makes filters only for it, which is a problem for us.

I am trying to translate some ".shader" files to ".fx" with the NVIDIA CG Toolkit (for use with WinUAE), but the cgc compiler always warns about all the implicit casts that the code does. It doesnt supports this? How I can compile the code, without the need to add type-casting for any variable? The toolkit is a real compiler, that translates source code to bytecode, or it acts like a translator, too?

OpenGL is unfortunately second class citizen on Windows which means lots of all kinds of strange issues I don't want to troubleshoot..

It was removed long time ago because there was no simple shader "framework" like D3D had and OpenGL didn't handle fullscreen or vsync as nicely as D3D. (Probably due to really crappy ATI drivers at that time..)
