Question / Help Display Capture Lag in Win10 (Semi-Solved)

[Panicintrinsica]

Is anyone else experiencing massive hang-ups and lag when using the Display Capture method? I assume it has something to do with the “aero” problem, but I’ve not found any work-arounds for that giving that Windows 10 does not have an “off” option.

Unfortunately, Display Capture is the only method that’s realistic for my purposes. Window capture works fine and is lag-free, but I’m switching between multiple applications with different window sizes and I can’t stop to resize and change options on the stream every time I change focus.

I see that there was an old plugin to fix this issue in Vista & 7, and it was not there at all in 8, but it seems to have come back again, at least on my system, and is making life needlessly difficult. I’d prefer not having to spend hundreds of dollars on a dedicated capture card at the moment just to make something work correctly.

Can you post a log which covers a stream? I did a stream the other day which was pure Display Capture and it seemed fine, I was doing some coding and was swapping windows repeatedly without an issue

Here's a test stream I just did. The lagging seems to be minor to debilitating depending on what I'm doing. For instance, if I open up the start menu and then mouse over anything in it, the screen completely freezes for about 4 to 10 seconds before unsticking again, if I open up the windows magnifier then the mouse starts slowly gliding around with at least a one second response time.

Apart from just windows, I tried playing the new Unreal Tournament so I get could get some high-movement activity on the stream, and the entire game was running at a very visible delay. I normally get north of 100fps while streaming with window capture. I did not check my frame-rate, but it was noticeably halting every couple frames and made it look like my computer was dying. It's not my CPU, GPU or Memory, as none of those have capped out (CPU maxed out at 78%, GPU at 54% and RAM at 30%), and as I said, it only happens when I use Display Capture, so, idk.

Update: I formatted my drive and reinstalled Win10 to fix some unrelated issues, and the display capture lag seems to have gone away as well. I still have no idea what could have been causing it, since I'm using the exact same drivers and settings as I was on the previous install, and obviously drivers were the first thing I checked anyway, but whatever it was is obviously gone now.

I guess if anyone else runs into this issue, it's apparently not inherent with Windows 10 itself, something else is causing it, but what exactly I do not know.
