Quake wars also showing performance drop for DX10 over DX9

[SUBMAN1]

I guess we already know that DX9 run faster than DX10, but here is a new game coming on the market to further catagorize the performance decline of going to DX10.

Errr, the graph you linked only shows the performance difference with operating systems, not DX9 or 10.
While all of our tests were conducted under Windows Vista 64-bit, we decided to run a few tests using Windows XP to see the difference it would make.

As the old story tells, games will run better in XP, and Enemy Territory : Quake Wars is no exception. While the margins were not earth-shattering (for which you may also want to feel proud of the advancement on Vista's drivers), it is still disappointing to find a DX9 game running slower in Microsoft's latest operating system.
