I was a W8 enthusiast. I tried the RTM on my desktop pc without installing too much stuff. Actually it was just to familiarize with the new interface and everything looked pretty and cool. Fast booting, virtually a couple of issue and incompatibility that I did not even experienced but could suspect... So I upgraded my notebook (my primary machine) to W8 Pro. And obviously, everything looked pretty and cool. I installed my usual software, discovered a couple of issues with fifa 13. I don't know if it's a problem with the Nvidia drivers for my video card, or EA that hasn't released a proper patch up to now that grant a full compatibility with W8. So I wasn't 100% satisfied but what made me write this thread is when I opened a 81-page word 2013 document and the scroll and typing lag. I disabled the hardware acceleration as suggested in some blog I found googling the problem, but this worked yesterday, today it lags even more. Just scrolling the page of the document uses my cpu resources for a 24-26% (I have an i-5 2.27ghz). So I can't tolerate that the latest softwares for microsoft is so badly optimized. I am confident that they fix all these errors because in this way a simple task like using a word processor is just frustrating and almost impossible.
