Battlefield 4 Benchmark – MP CPU and GPU W7 vs W8.1
Still some optimization issues... http://www.hardwarepal.com/battlefield-4-benchmark-mp-cpu-gpu-w7-vs-w8-1/

That's because windows 8.1 uses Direct X 11.1. Windows 7 just has 11.
DX 11 and DX11.1 are for GPU's not CPu's
I know that... That is why the benchmarks are showing higher FPS under Win 8.1
EDIT: Also, any CPU with integrated graphics also utilizes Direct X - so in a way CPUs do use it, but integrated graphics isn't really used for gaming.
If it was DX11.1 you would have had equal ratio between resolutions and settings when you compare W7 and W8. However in this case the more you go down with resolution and settings you get much more frames on W8. More frames means more work for CPu which means that in this case CPU optmization is crucial and how the OS uses it.
