Hi!

On a 120hz monitor, I noticed Windows 8.1 x64 RTM has very poor window movement compared to Windows 8 x64. It makes the OS feel kinda sluggish compared to 8. Has anyone else noticed this?

here is a video example

I have the exact same problem. For me its related to the secondary screen I have attached. I actually had the problem on windows 7 as well and removing the second screen fixed it there also. I did find I needed to reinstall the drivers after upgrade but it only partially fixed the issue.

it was a driver issue for me

with the latest nVIDIA drivers I get poor 2D performance, like when I play Solitaire even the cards stutter when in motion, I have a freakin' GTX 770M for god's sake and I can't even play Solitaire

going back to an older nVIDIA driver provided by ASUS fixed the problem so now I only stick to drivers provided by my laptop manufacturer

Thanks for the suggestions

@BrightCandle
Both screens work well together at 120hz in Windows 8. I also tried each display separately, no improvement.

@berryracer
No 2d performance is excellent, Solitaire and minimizing windows is fuild at 120fps, only moving windows around are at 60fps. I tried uninstalling geforce drivers, reboot and let windows install them from windows update, still same problem. drivers 331.58 is also bad. I fear it has something to do with Windows 8.1 WDM rendering engine.

What happens for me is if I put a few Windows on the secondary screen and then move things around on the main screen the Windows and even highlighting text is slow and laggy on the mainscreen. I think its to do with SLI, it accelerates the primary screen but the secondary screens doesn't get accelerated (According to NVidias control panel) and for whatever reason that causes this stutter on the primary (and secondary displays).

I have had more serious problems in Windows 7 where even turning on a second display at all would cause the primary display to have graphical performance problems. Windows 8 fixed that for me and Windows 8.1 did something a little different to 8 as well. I think its partly Windows fault, I saw some other related problems on 2x 7970's so I think Windows is involved since it goes across vendors.
