Lost Planet: Extreme Condition faster in DX9 than DX10

| Posted: May 17, 2007 9:44 am

Our good friends over at the FiringSquad have given Lost Planet: Extreme Condition a thrashing and come up with some rather interesting results. First and most importantly, this is the only demo so far to make an appearance that works under both DX9 and DX10. It seems to eat most graphics cards for breakfast if you crank up the resolution or the features just the tiniest bit. But it's not those benchmark numbers that matters, it's the ones that compare the DX9 to the DX10 version of the demo that are really interesting.


We all had high hopes for DX10, but so far it's been nothing but a letdown and it seems like Lost Planet: Extreme Condition isn't proving it to be any better. This could of course be entirely up to the graphics cards drivers though, so hopefully the chaps over at AMD and Nvidia will sort this out pronto. Considering that the test card used is an 8800 Ultra, you'd think it wouldn't have any problems with the game. Under DX9 it's all fine and dandy, although don't expect to see this game hit 100 FPS any time soon, but under DX10 it is between 7-12 FPS slower than under DX9, both results in Windows Vista.


As you can see, the DX9 codepath currently runs faster than the DX10 version. At 1600x1200 the DX10 codepath ran 16% slower than DX9, both under Windows Vista with the GeForce 8800 Ultra in the snow demo, and 2% under the cave sequence. This is with 4xAA/16xAF enabled, and HDR lighting set to medium.


This was a bit of a surprise to us considering that the DX10 version of Lost Planet was intended to run faster than the DX9 version. It looks like a little more driver work is needed in order for that to happen.
