Games and Dual Monitors

Hey everyone. I'm having some weird issues with my dual monitor setup.
If I play a game in fullscreen, any video playing on the second monitor lags and delays heavily. If I minimize the game, the video in the second screen runs fine. It doesn't seem to matter which game it is, and it's only with games. If I run 2 videos in full screen on both monitors, both run fluid. This wasn't an issue in Win7 so I'm wondering what's wrong for me in Win8.

I can run a metro game full screen on (mahjong)one monitor and a video full screen on the other.
or live tv in media center and a video OK obviously the sound is overlapped.
Are you talking about a more intensive both graphics and cpu on the desktop, and a video on the desktop,
if so I cannot really help as no "real" games are on my W8 system.
But a good guess it is the graphics driver in built into 8 and we need to wait until the individual drivers are optimised for W8

Hi there
i got exactly the same problem as rombeau4
some help would be very helpful i just do not switch back to seven because i am almost sleeping in front of my computer
PS: playing some "real" game on first display (team fortress2, though far from the most demanding resources)
video on second display
when the video is in full screen it stutters like hell and delay

i was wondering, could it be a ram issue? or do i have to check the flash player

Hey.

I think the problem is caused by the os itself where they thought it was a good idea to cap the framerate of windows which are "in background" to the fullscreen application. It was probably implemented to save power for battery powered units. This is just my guess though..

Maybe there is a registry key or something which changes this behaviour?

hey godotsan that would be a good guess maybe because i noticed every application seems framerate-capped on the second screen

due to that and additional compatibility driver issues i switched back to windows 7 and probably wait for a release version

Yeah this would mess up my HTPC setup BIGTIME.

Hopefully fixed in RTM, I really hate seeing things go backwards :/

Does someone know if this was fixed in RTM ?
Does anyone have a fix ? I really can't stand this...

Exact same issue here. It seems impossible to play any kind of video (it doesn't matter if it is in VLC or Youtube or anything else) in the second monitor, while simultaneously playing a game in the first monitor in the multi-monitor setup.

Any help appreciated, because this is annoying to the degree that I am considering going back to Win 7 ... :/

I don't think it has been said yet, but when I upgraded from RP to RTM (no reformatting, just upgrade) the issue was fixed for a moment. For some reason, it came back later. I don't know if it came from installing the Nvidia Drivers or from a Windows Update or from something else.

But gosh, it sucks..

It is unlikely that it's the Nvidia Drivers since I have an ATI graphics card (and the latest catalyst drivers). Since it also does not matter which game you start or how you watch the video, it seems like a more fundamental issue. It was rumored somewhere that it is some kind of power-saving mode for background application causing this, but it seems to be just speculation.

I figured out that if you put the games in compatibility mode - windows 7, the lag will go away completely....

Worked for me, I'm on Windows 8 pro

Asus Crosshair IV Formula
10GB RAM
AMD Phenom II x4 955
AMD RADEON HD 5750

That's true ! Thanks for the tip. Kind of a pain though.

I agree, Microsoft should really look into this and change it. At least make the background fps cap an option so desktops who don't really care about battery consumption can turn it off....

Seems to be fixed as of now.

Microsoft fixed this bug. It was an issue since release. Here are the updates I installed to fix it. I believe it is KB2756872. Here are the links.

Windows 8 Client and Windows Server 2012 General Availability Cumulative Update
Windows 8 and Windows Server 2012 cumulative update: November 2012
Windows 8 and Windows Server 2012 cumulative update: January 2013
Windows 8 and Windows Server 2012 cumulative update: December 2012
A servicing stack update is available for Windows 8 and Windows Server 2012

I have all of those updates (I tried to install them again anyway but no go) and still have this problem. Switching to Win7 mode on the game does work for me though. It happens with all video players (VLC WMP PotPlayer) and all browser players Flash, HTML5, and Silverlight. VLC actually crashes and says it has to do with Direct3D. Amazon Instant refreshes the page and detects it as a monitor being unplugged. But if I don't change the compatibility to W7 it doesn't crash anything but plays at 4fps.
