Right, I get your point, but that's not how I meant it. By "OpenGL can run DX10" I didn't mean it in the way that OpenGL could make Microshit's DirectX10 run on systems that are not compatible with Microshit's DirectX10.
OpenGL is an alternative to DX10, so what I meant is that via OpenGL you can have the same effects that are only possible with DX10.
And by "even though it wouldn't make much sense" I meant exactly what you wrote about processing power. Even though it'd be possible to create those effects, the Wii wouldn't just be able to handle it. It's too weak.
Bump Mapping, how ever, isn't really that big of a deal. The Xbox had it, some Gamecube titles had it, even the f*cking NGage had Normal Maps.
