No worries, not intending to change your mind, but I try testing my sp3.
I go over to
Apple - iPhone 6 no shutter (beside the apple site, have open 20 tabs in IE desktop, -hardwarezone, yahoo.com.sg, facebook, gmail, yahoo mail, dpreview at gallery viewing images, ebay, qooo10.com and other etc sites, memory usage is at 1.4GB for IE alone, running a notepad and a hardware monitoring sw and the task manager . Tried facebook with pictures and videos.. no shutter..
Also tried
Apple - Apple Watch with the 5 big image swapping right to left, I can scroll up and down with no shutter even while the image is changing and I am scrolling.. my current CPU package temperature is at 44 degree C.
Tried auto-hide taskbar, no spikes I can see
(note: running at 599MHz CPU usage went up about 5% or less, not really a spike.. fixed cpu speed at 1497MhHz,, cpu goes up 1% or less cpu temp at about 46C)
I do a encoding of a 2GB mp4 video file using ffmpeg (cpu up to 100% 1497MHz cpu temp at 66C memory at 74%) with ie still open with 20 tabs and tried again with the apple site... iphone6.. no lag or shutter... I scroll up.. and down quickly.. page follows... using a Bluetooth 3.0 HP Z5000 mouse
My indexing is not turn off, my hibernation file is always there.(at default 75% of memory - 3GB).. fixed my pagefile to 1GB... disable InstantGo.. running on main plug power... not using the default MS graphics driver but the latest Intel HD graphics driver 3907
