This will enable people to not only see the game, but also get an idea of how it will run.
X² uses nearly every 3D technique available so the benchmark will provide a quite good overview on how well the actual performance (especially of graphcis adapter) is. As has been done in the older X-BtF demo the new benchmark will store the frames for each scene seperately so you can easily see the pros and cons of the techniques used in that specific scene. It is also important to say that the demo will turn AQC (Automatic Quality Control) OFF so the benchmark results can be compared.
