I had to rebuild my system this past weekend. Messed up the dual boot to both Windows 8.1 and Windows 10, and couldn't recover from my partition images...

So... Fresh install of both and now correctly configured to dual boot.

As instructed by another poster, this appears to have solved my windows 10 render times and FPS issues.

For the time being, everything is purring along nicely. Just have to get everything else back on that system I use on a daily basis.

I too suffered at one time, the dxgmms2.sys BSOD that xbamaris mentions until a recent update, but then I suffered the high render times and low frame rates until I updated the driver, basically on a daily basis.

I do hope Martin, that your request to Microsoft is resolved quickly. Honestly though I don't think they are too concerned about it.

Great news! The latest updates released today for Windows 10 resolves the dxgmms2.sys issue and may resolve other issues as well.

The updates are:

Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3140743)
Update for Windows 10 Version 1511 for x64-based Systems (KB3139907)

Hi guys

After downloading the latest build and installing to 1511 with both those updates.
I can confirm that it fixed the dxgmms2.sys BSOD error and so far no further crashes.....at the moment ;) .....touch wood.

But do still have issue with internal Intel HD 4600 driver control panel not working
use this with my Nvidia GTX 980ti to give me a virtual monitor or extra hdmi out port. People have reported this previously but
didn't do much research on as I was following the dxgmms2.sys issue.

Will also see how the performance is over next week or so.



----Update---
Fixed the Intel HD 4600 control panel issue with reinstalling the motherboard ASUS z97 deluxe video driver again
and updated successfully. Both Nvidia and on board Intel HD working normally again

I have been doing a lot of testing on this update and so far i am having no blue screen issues so far. Going to be trying it on the MMA event i'm switching on tonight. Wish me luck. (yes I do like to live dangerously)

Does this mean that it's now safe to upgrade to Windows 10? My production machine is still running Windows 7 and the only reason I have been holding off on upgrading is the issues with vMix.

I made the jump to Windows 10 on my production machine this weekend and immediately had issues. Some crazy process called "System and Compressed Memory" would immediately jump to 12%-15% of the CPU when vMix was launched and would never settle down. After hours of research that lead to no improvements, I decided to start with a fresh profile, or what ever it is called. No shots loaded except for the 2 blanks you start off with. Then I started recreating shots one by one. When I got to my first C920 webcam System and Compressed Memory process jumped to 6%+ and then when I loaded the 2nd C920, it jumped to 12%+. I could repeat this over and over again.

I was brining the C920's in at 1280x720, NTSC 30p and RGB24, which was the default I guess because it's not something I picked, but it also never gave me issues before with Windows 7. Once I changed them to MJPG, System and Compressed Memory process went down to 1% or less with both C920's loaded.

Last night was our first show (which was over an hour) since upgrading to vMix 17 and Windows 10. Not a single problem, other than my mistakes, during the entire show and the CPU remained around 40% - 50% most of the time.

Thanks for the info. I don't remember "System" taking up as much CPU under Windows 7, but I can't be sure or even check it out now since I am 100% Windows 10. What I do know is that under Windows 7, with vMix running and my standard shots loaded, but no streaming or recording, my i7 3770k system would be around 20% or lower total CPU (per Task Manager). Under the same conditions in Windows 10 it was running over 40% and sometimes hitting 50%. Maybe I have something else wrong as well and will keep looking. Want to make this system last a little longer before building a new one.

I've upgraded 4 of our computers so far.

the issue I have encountered on both computers running vmix 106 is the BCC950 webcam (first input) says offline when loading the profile so no picture (and audio seems to have been lost on the 2nd computer for the first Input to when the profile is loaded). When the old Profile is loaded, 'Offline' is added in front of BCC950 ConferenceCam Input Title ("Offline BCC950 ConferenceCam").

I had to go back and do a 'Change' on that input resetting the camera and audio


Any reason why that would happen?

Did a MMA event on the weekend, it did feel a bit more faster but that can be subjective. Nothing major broke so im all happy.

I just installed the anniversary update and now neither of my C920 webcams can be added using the MJPG video format like they were before the update. Looks like the only format supported now is YUY2. Also, not sure if this was there before and I just didn't notice it, but there is a process running called Windows Camera Frame Server and it's using over 2% CPU when I have both my C920 added to vix.

Found this article which seems to confirm the problem with USB cameras and the MJPG format. https://www.mgraves.org/...sb-camera-functionality/
