Well i get that crap with OBS Classic on Win10 14936 (newer than AU) and 372.90 GPU driver:
Texture Map failed: 0x887a0005 0x887a0006
Video card or driver froze.
It could also occur if you have enabled OpenCL in x264 settings (i did not as far as i know, default x264 settings here, but DOOM might kick in here).
This affects DOOM and OBS Classic.
Since Vulkan is added to other engines right now, we might see more of that in the near future.
With OBS Studio i dont get that texture error, but a truckload of different things that dont even produce errors or have logs so i could link it.
But classic works better with the webcam. I have the usual suspect, the C920, could test an older cheap Creative VF700 720p one - for more information. If the C920 had issues, the forum would be already down, since that webcam is by far the most used for streaming blah.
Edit: never had any issues with the webcam on previous insider builds. Nope. 100% functional in OBS classic, skype and few other instances. Like i said, C920 - that webcam would not slip through if it had huge issues with one of the builds before.
I'm not surprised that the 887A0005 error would occur in OBS Classic, but since the issue does not occur on my computer, I cannot personally test it. I'm relying on reports and information from others, and since I primarily read the OBS Studio Windows Support forum (where I can most effectively troubleshoot other problems), I don't usually see reports from OBS Classic users. I've asked a few community members to test this and can now confirm it does also occur on OBS Classic.
As far as I know, adding OpenCL to your custom x264 settings has no actual tangible benefit and will only cause issues.
All I know about Vulkan is that Game Capture for Vulkan (and DX12) is not yet supported. The issue occurs on many games from recent games (ARK, Battlefield 1, Dark Souls 3, Dead By Daylight, Overwatch, etc.) to older games (BioShock, World of Warcraft, Minecraft, etc.). It can even occur while not running/capturing a game at all. Given this information, I'm not sure how more widespread adoption of Vulkan will increase the number of occurrences of this issue.
The issue I've addressed in this thread (not the webcam issue) seems to occur most commonly when the graphics card is under heavy load. If Vulkan creates more load on a graphics card than DX11, then perhaps that could cause it to occur more often, but that's unknown at this time.
Regarding the webcam issue, at the risk of going outside the intended scope of this thead...
That's the thing though. The C920 was most definitely broken by Win10AU (see
this thread and
this MSDN thread), even in previous Insider Builds (see
this post in the MSDN thread, which shows the issue was reported
here). It has supposedly been partially fixed in a recent Windows Update (KB3176938, noted
here by Logitech). And again, it was
all UVC devices, not just the C920.
As a result of the extreme webcam issues with AU, Microsoft may have slowed down the rollout to give them more time to check their telemetry data during their phased rollout (this has been posted by several online tech news outlets). By the time the rollout expanded, KB3176938 may have arrived, which jives with the fact that most reports I saw arrived in September (after the August 31, 2016 delivery date for KB3176938). I've done a lot of reading and research on the subject.
That is just the thing. As I stated I have of the workarounds listed above except for reverting back to an older version of windows.
You tried every single workaround (except trying an earlier version of Windows) and none of them worked? Your previous log shows that you are still on the latest Windows 10 patch, which means you didn't rollback any Windows Updates, or they immediately reinstalled themselves. What Nvidia drivers were you using when you first saw this problem, and what drivers did you rollback to?
