Windows 10 UI lag? when having multiple monitors connected
Hello
My specs: MSI GTX770 2GB ram with nvidia driver 378.49), i7-3770K, 16GB ram, ...
The little problem that I noticed:
Hovering over the icons on my desktop (around 12 icons) is slow. It seems there is a display lag when hovering over a couple of icons in a row.
If the first icon is highlighted and I then move to another icon while in the process hovering over other icons the icons in between are not highlighted.
The selection of desktop icons is also slow, I see the square increasing with steps.
Another symptom is switching Itunes to the miniplayer view and back is slow as hell.
Itunes disappears and around 7 seconds later the miniplayer is shown. This is the same for switching the miniplayer to normal view.
What I notice is that when I'm waiting for the miniplayer to appear and press CTRL+ALT+Delete and instantly escape that windows overlay screen, the miniplayer shows. So it seems to me as windows is not refreshing the screen or something. When I'm waiting for the miniplayer to appear I see a process in taskmanager "client server runtime process" jumping to around 6-7% until the miniplayer appears. Normally this process is taking up 1-2% procent.
What I have found so far:
- If I reinstall nvidia drivers via Geforce Experience the problem goes away. The problem here is that I need to reinstall everytime windows restarts.
- After that I found that the problem only happens when I have enabled my second monitor. As soon as I disable the second monitor the problem goes away. This leads me to believe there is a problem using multiple monitors.
I then tried to debug using all combinations of 2 monitors (and I have 4 available so a lot of combo's) and the problem was always there when activating the second monitor.
I have tried searching on google but all I ever get are the standard windows 10 laggy things and general fixes. What I have also found is to set the refresh rate of all connected monitors to the same (60gHz) but this does nothing as they already were at 60. Switching the resolution to something else and then back does nothing as well.
Maybe some other important thing that I have noticed is that when I have 2 monitors enabled and have a fullscreen window on the background of my primary monitor (like firefox maximized). I then open itunes so it is on top of firefox, then show the miniplayer it is instant. As soon as 1 pixel from the desktop is shown (firefox not maximized) the lag reappears.
I recently reinstalled windows 10 hoping to solve this problem but it didn't do nothing to solve the problem.
My monitors are both connected to DVI btw.
I also tried using the integrated graphics for the second monitor but the exact same problem appears.
I also tried clean driver installs. And the NVIDIA driver version didn't seem to matter because I have this problem over a couple of driver iterations.
I am currently at a dead end and don't know what else I could try.
