Hi, I'm Jenn, also new to these forums.
I stumbled upon a problem when switching from Windows 7 x64 to Windows 8.1 Pro x64.
I have the EXACT same setup, same laptop, same hardware, same configuration, everything.
Windows 7 never did anything like the problem I now have in Win 8.1. Here's the problem;
Whenever I record or stream in OBS, after 1-5 minutes the screen blinks, and hangs the graphics of one, some or all the games. It doesn't hang the game, it just stops rendering the graphics -- I can still hear the sound and if I click around, I can hear myself interacting with it. I have ALL the latest drivers for the computer, motherboard, ALL devices including graphics cards etc. Also ALL Windows Updates installed, nothing more to install. The computer itself came with Windows 8.1 pro x64 with the authentication sticker underneath, containing the CD-key. I just didn't like W8 from the beginning and that's why I haven't used it until now. However, W8 is faster, renders things faster (like visualizers, spectrum analyzers and so on) so I'd like to keep using it.
Both OBS and QSVHelper.exe are specifically set to use only the Nvidia adapter, forcibly through the Nvidia Control Panel, so it's not a switching graphics problem because it's a laptop. The default setting in Nvidia Control Panel is to use the Nvidia graphics card aswell. Also, none of this was ever a problem in Windows 7. I'm not using the QuickSync function.
I'm going to include some things here that aren't exclusive to Open Broadcaster, but can be helpful in troubleshooting, just for the sake of it. So, here's what I gathered from event viewer right when it happened;
So as you can see, DWM is logging in and out some account that can be all the way up to DWM-7 from what I've seen so far. It just logs in, sets some parameters and the directly logs out. This is a ONE-user system, Only my user account is on it, and remote login has been disabled. In Windows 7, at least DWM could be disabled - not that I ever had to, because it worked with all my stuff, but seeing as DWM is screwing up totally in Win8, I thought I'd just disable the server, but it's nowhere to be found. Also, it seems Microsoft changed how it works, the system has been redesigned to generate an OK even if it's still on, like this example below:
DwmEnableComposition( DWM_EC_DISABLECOMPOSITION ) does not work on Windows 8, even though it returns S_OK. Confirmation is by calling DwmIsCompositionEnabled(), which shows the former function had no effect.
There's only 1 dwm.exe running:
There's only 1 user logged in (me):
Here's the complete user list of the system:
And here's the system information from my computer itself:
System:
Devices:
Running only 1 game at a time is not an option for me, since I'm multiboxing World of Warcraft (7x).
^ I wrote all of that 2 days ago, and I've had some time to check some more stuff. If I run OBS in W7 compatibility-mode, I get a completely black video when recording and streaming, it's also pitch black in the preview, whichever graphics card I choose in the settings (Intel HD Graphics 4600 and NVIDIA GeForce GTX880M). However, when I have it in W7-compatiblity-mode, I get another option -- Microsoft Basic Render Driver. When using that one it actually works, but I'm getting down from 120+ FPS (when all 7 WoW's are running) down to about 15-20 fps and lags. I have no idea where to continue, I've really thought of everything I could here, and I need some help figuring this one out.
I used OBS to record all 7 WoW's using desktop-streaming as I've always done, with Windows 7. Here's what it looks like when using Windows 7, just to show what I mean, what I'm doing and that it's working out VERY well:
