We've already heard that Microsoft plans to make use of GPU acceleration in Windows 7, but it looks like the company is also going to be doing its part for the GPU-less out there, with the OS's new so-called WARP system promising to allow for DirectX 10 acceleration using nothing more than a plain old CPU. Among other things, that's apparently being done to avoid a recurrence of the Vista-capable debacle that happened last time around, when some systems that were said to be capable of running the OS were, in fact, anything but. According to Microsoft, WARP (or Windows Advanced Rasterization Platform) will work with as little as an 800MHz CPU, although it says it'll work better on multi-core processors with SSE 4.1. To really put it to the test, Microsoft apparently even went so far as to run a few Crysis benchmarks with the system, and managed to clock in a blistering 7.36 fps frame rate at 800 x 600 on a Core i7-equipped PC, which is actually slightly better than what Intel's current integrated graphics were able to eke out.
