I'v read it. DirectX 9 also have shaders as I know. I did some 3d vision shader modifications when it was not dropped. How it is related to my question?

As I understand it, the fundamental barriers to supporting shader based d3d9 games, d3d10 games, and d3d11 games are all the same - needing to be able to reconstruct a scene based on the data passed to a game's arbitrary shaders.

Is remixing shader based games with reasonable performance on modern hardware possible? We don't know. We've discussed a few approaches internally, but there are lots of unsolved problems here. Right now our priority is more on getting fixed function d3d9 games working well, and there's plenty to keep us busy there.

Is it not possible to fix by shaders disable/replace? Like helix did to fix shaders not supporting stereoscopy? Yes its maybe not possible to automate it. But just give people tool to work with shaders and...
