High-end: Call of Duty: World at War

Call of Duty: World at War is a WWII-based shooter built on the Call of Duty 4 engine with a little flair added.  The game is unique in the genre as it sets the game at the Pacific stage rather than the much more common, and less controversial, European front.

For our testing with CoD: WaW we ran through the level of the game shown above while recording in FRAPS to get our frame rate comparisons below.  The game plays almost exactly like CoD 4 (a good thing) so our testing methods were reliable and repeatable.

As we get into the more expensive graphics cards, expectations are going to be higher.  Here we can see that the performance differences between Windows 7 and Windows Vista are minimal, both with the NVIDIA and AMD driver offerings.  In terms of GPU versus GPU performance, the AMD card at first appears to be the bigger winner when look at just the average frame rate, however, looking at the minimum frame rate the HD 4870 X2 is clearly taking a big hit.  The line graphs above clearly show where that is taking place.

What is interesting about that spot is that in the game, we see a “slow down” of time AND frame rate and then a “fast mode” as the game basically catches up with what should really be going on at the time.  Audio isn’t affected – it plays at the correct speed the entire time.  I think what we are seeing is a bug with CrossFire in general as it happened on BOTH Vista and Windows 7.
