hi.. there ahh i want figure out which Operating system gives a better perforamnce for gaming Windows 7 Ultimate.. or Windows 8.1 Pro..????
Windows 8.1 has a few slight advantages over Windows 7.
1. Smaller memory footprint. This is nice for resource constrained computers
2. DirectX 11.2. Most modern AMD and NVidia graphics cards will see a slight boost in applications that use DirectX 11.1/11.2 codepaths when used with Windows 8 / windows 8.1 respectively.
3. Native support for SSDs. Windows 7 handles SSDs quite nicely at the filesystem and driver layer, but Windows 8 handles them natively.
4. Fast boot. Nuff said.
5. Lighter WDM, no Aero interface. This puts less compositing work on the GPU and causes less compatibility problems.
6. WDDM 1.2 (Windows 8) and WDDM 1.3 (Windows 8.1) enable much improved display drivers and multi-display handling
7. The new start menu isn't bad at all. It takes about 30 minutes to get used to.
