WiC Benchmark Results

The latest version of Massive's proprietary Masstech engine utilizes DX10 technology and features advanced lighting and physics effects, and allows for a full 360 degree range of camera control. Massive's MassTech engine scales down to accommodate a wide range of PC specifications, if you've played a modern PC game within the last two years, you'll be able to play World in Conflict.

World in Conflict's FPS-like control scheme and 360-degree camera make its action-strategy game play accessible to strategy fans and fans of other genres... if you love strategy, you'll love World in Conflict. If you've never played strategy, World in Conflict is the strategy game to try.

World in Conflict offers an in-game benchmark, which records the minimum, average, and maximum frame rates during the test. Very recently another hardware review website made the assertion that these tests are worthless, but we couldn't disagree more. When used to compare the same component on two separate platforms, the in-game benchmark works very well. This doesn't prove to be the case when comparing different GPU's, however.

For World in Conflict testing, only the Gigabyte GA-EP45T-EXTREME and GA-X48T-DQ6 were compared. With the Intel E8400 CPU lightly overclocked to 3600 MHz and the Corsair PC3-14400 DDR3 working at 1800 MHz, each product was matched with the same video card so that architectural differences might indicate a performance advantage. At least, that was my plan.

This is the reason behind the low-end resolution of 1280x1024, because at 1.3 MP the software becomes more dependant on the system hardware to keep up with demands than it does the graphics hardware.


As it turns out, P45 might have some strengths in drive I/O with the new ICH10 Southbridge, but the diced-up graphics pipeline isn't done any favors by the P45 Express Northbridge. In our tests, nearly all of the single-card configurations were identical (1 FPS is a safe margin of error). However, when we placed the Sapphire Radeon HD 4850 Video Card 100242L into a CrossFireX set with an identical card there was a slight difference seen in performance. Changing the CrossFireX set to include the high-performance Sapphire Radeon HD 4870 Video Card 100243L only broadened the difference.

In concluding our World in Conflict test results, it appears that the Gigabyte GA-EP45T-EXTREME might offer CrossFireX configurations gamers but only at the expense of performance each card is reduced from 16 to 8 lanes of bandwidth. The differences weren't very big, falling between 5-6% for the Radeon 4850 and 4870 CrossFireX set we tested, but they exist. If you plan to use only one or two graphics cards, the Gigabyte GA-X48T-DQ6 can put the PCI Express 2.0 bandwidth to better use.
