Question / Help Desktop Lagging with OBS Open

[besweeet]

(The only recent change is that I recently installed a GTX 1060. With my 7950 and HD 3000 IGPU, this never happened.)

As soon as I open OBS, my entire desktop and anything else will begin to lag. For example, dragging windows around the desktop is noticeably sluggish. Playback of videos is also sluggish. As soon, as I close OBS, everything goes back to normal. This happens regardless of whether I have NVENC, x264, or QuickSync selected as an encoder.

What's worse is that, after I click on start recording, the entire desktop will freeze up for nearly 30 seconds before allowing me to use it, albeit at the sluggish frame rate.

After I close out of OBS and view the recorded video, it's quite sluggish and isn't silky smooth like it was prior to installing the GTX 1060.

I have no idea what could be causing this, but it's now preventing me from using OBS. I might have to take advantage of that free 1 year XSplit Premium license that came with my new GPU...

I can literally begin moving a window around my desktop while OBS is loading, then as soon as the OBS window comes up, the smoothness of the moving window gets cut in half (if not more).

Additional information: After OBS opens up, if I try to open a Windows 10-specific application (such as Windows 10's Mail app), this is when everything will freeze for a while. After it unfreezes, if I continue to try and interact with it (even move the mouse over the window), that's when the entire screen will freeze again for a bit. Again, as soon as I close OBS, everything works perfectly. That is regardless of if I'm streaming / recording or not. Interestingly, if I try and interact with a W10 app with only the keyboard, there are no issues (except for the entire desktop's frame rate becoming sluggish).

Another update: I noticed that Desktop Window Manager in Task Manager constantly uses 11-13% CPU usage. If I kill dwm.exe, everything works normally.

Connect both of your screens to the Nvidia GPU.

I only have one screen. The secondary display is an invisible / virtual display. When I had my 7950 (and without that; just using the HD 3000), I never had any issues like this. Since killing dwm.exe has "fixed" this, I'll just do that whenever I decide to use OBS.

I'm having this issue except it locks my game to 30fps and all I can see to fix it is killing DMW as well. Going full screen seems to fix it as well. Also if I don't give it admin it fixes the issue but that's only if I do window capture instead of display capture.
Here it is without admin in display mode get 30fps drop

Here is in admin mode with me killing DMW a few times, just restarts.

Guess I might use xsplit too.
