Hello. I have Windows 8.1 x64 installed to Dell M4600 laptop (using Nvidia Quadro 1000M) and Nvidia driver version 332.21 (newest atm). I have a weard problem. Screen is somekind  sluggish and slow when browsing web pages and in windows explorer too. It's not that slow like eg. using old windows xp without display driver. I have tried 3 different Nvidia drivers and everytime when I reinstall the driver everything works normally but after some time the sluggish screen comes back. Weard.
