They have yet to make a game, period. It's been years since their last game, they only buy out hl2 mods and put a $50 tag on them nowadays. Their old source engine cannot do DX10 too.

Of all the thing Stardock said Elemental would support which it doesn't, the shader model hardly seems worth attention. What would the game really get out of it anyway? There needs to be a reason to use some of this stuff given how relatively few computers have access to it, and with Elemental's graphics I'm not sure you'd get anything out of it.

The thing I'm liking in Steam's numbers is that 64 bit and multicore are becoming the norm. As we see games taking more advantage of those, we'll see some nice things happening.
