Lost Planet Performance and DX10

The first game to support DirectX 10 out of the box is on the shelves. We will take a quick look at GPU performance scaling as well as DX9 versus DX10 image quality with screenshot comparisons. Is it time to upgrade to Vista for DX10?

System Test Setup

For evaluation we are using an EVGA NVIDIA nForce 680i SLI motherboard, an Intel Core 2 Duo X6800 2.93 GHz processor, and 2GB of Corsair XMS2 Dominator CM2X1024-8888C4D at 4-4-4-12 1T. We are using the latest chipset drivers available and the latest BIOS at time of evaluation.

Video Card Comparison Setup

For this comparison we are using stock, default clock speeds on all video cards. So keep in mind that factory overclocked video cards you can purchase may show slightly better performance. This was done to give everyone a “fair” playing field since we are observing how these GPUs scale instead of looking at specific video card performance. With the 320 MB and 640 MB 8800 GTS having the same clock speeds we can see exactly how RAM capacity impacts these two GeForce products in relation to Lost Planet performance. We are using a freshly installed Windows Vista Ultimate x64 Edition as well as the latest beta drivers from NVIDIA and ATI including a yet-to-be released Catalyst 7.8 for the ATI Radeon HD 2900 XT that fixes AF for Lost Planet.
