Hmm, the graphics card itself should be more than capable of running the game, as far as I can tell. Really weird. I don't know if it's the driver then. I double-checked the shader too, but it passes the standard conformance tests, so I don't know why it wouldn't work. I might give the game a better poke at some point - maybe even make a browser build out of it - but it's likely going to take a good while since the code base is old and I'm busy with my Next Big Thing too. 😕
