Section IV Performance – Gaming
Gaming as a test of motherboard performance is sort of a joke these days. The big player in the gaming arena is the GPU. Everyone but a few hardcore PR teams know this. However, it is important to run at least a few (one from each current DX version) to see if there are any issues with the combination of components on a motherboard. These are items like Audio lag, memory lag and of course problems with the PCIe lanes and signal traces. If there are issues in design, drivers or BIOS then you can have odd gaming performance. So without much more preamble let’s dive into the three games we currently use; Call of Duty Modern Warfare 2 for DX9 FarCry 2 for DX10 and Battlefield Bad Company 2 for DX11.

Call of Duty Modern Warfare 2 DX9 -
This is an excellent but short game that put you right into the action from the beginning and does not let up the pressure until the very end. The graphics are a little better; most notably the night and thermal imaging have been improved. The AI is still the typical COD “bar fight” style AI, with maybe a tad more finesse. All in all it is not a bad game to play and a decent one to use for testing. Our testing run starts at the bridge and ends after you clear the school in the first level of the game. Settings are shown below as are the performance numbers.

Our gaming testing with Modern Warfare 2 does not show much of an improvement. However, as most games are not multi-core aware and are more concerned about the GPU we are not surprised to see this and considering the actual differences here it is almost no importance unless you are worried about the highest number…

FarCry2 DX10 -
Although not one of my favorite games this tedious game does have some good graphics. The large sandbox style of the game lends to mission based play. The only problem is that the AI is rather low grade. Still the more CPU power the more the bad guys try to do. Over all the game was a little bit of a disappointment to play, but still not a bad DX10 representation. Our testing run starts right after you get your first mission to clean out the safe-house and ends after the hostage rescue. Settings and performance numbers are shown below.

Well, well, FarCry 2 (and Intel optimized game) shows the X79Si on something of a comeback. The differences in frame rates are still extremely small (2-3FPS) which means that even this victory is nothing special and only of use for bragging rights.   


Battlefield Bad Company2 DX11 –
I have liked many of the Battlefield games. They usually tend to be fast paced and fun. With Battlefield Bad Company 2 you do get some of that, but there is something about the graphics and the movement that just does not sit right. The AI is a less sophisticated form of the bar fight AI, but it gets the job done. Still, the game is good for testing as it can put a strain on the components of the board. Out testing run is the entire first level, from beginning to end. Settings are shown below along with the raw numbers.

Ugh, Bad Company 2 puts the X79SI down at the bottom of the list. This time there is a much larger delta between the systems and there is a 20 FPS different between the number one slot and the X79SI. We hope this is a driver or BIOS issue but you can never tell.  

Gaming wrap-up -
The X79SI does ok at gaming. The frame rates are over our 32FPS standard (which is full fluid motion). It is not exactly the greatest gaming platform we have seen, but it is not the worst either. The audio on the board is ok for gaming and will get the job done; it is just not going to astonish you while doing so.
