[citation][nom]beetlejuicegr[/nom]i have an Intel i5 2500k oced to 4ghz, ati 5870 oc, 8gb ram ddr3 1866mhz, samsung 830 128gb..and i was really happy with my windows 7..then i installed windows 8 and i have to admit, apart from metro likeness or not, that they are way faster. What do i mean? i didn't expect to see a difference in performance on the OS by jumping to windows 8 and when i prepared everything i must say! you can see a huge difference in speed, on loading programs games and switching to desktop/metro etc.At least the memory management is way way better, couldn't believe it was possible for example,when you right click "my computer" and select "manage" ..how long does it take to load the management console?At windows 7 it takes some noticeable time (compared to other tasks) however at windows 8 its almost instant!I had some strange freezes on various games (more like lagspike feels ) and i knew it was from overclocking (some games don't like OC ). At windows 8 it is almost unnoticeable.Now DX11.1 , is most welcome, not because it will make people upgrade blablabla but because of the "With DirectX 11.1, WARP was enhanced with (among other things) support for DirectCompute and hence it is one of the accelerators for C++ AMP"Meaning , smaller PCs with just onboard intel or amd apu will perform way way better than on windows 7! for example netbooks and now that i think about it, it's time to test win8 on our netbook ^^[/citation]
As much as I like Windows 8, your experience seems more founded in that your Windows 8 installation is a fresh installation and your Windows 7 installation is not. Well ,that's what it seems like to me based on the difference on performance supposedly being huge. They should be very close.
