Latest Windows 10 update affects OBS performance with NVENC

Hi there!

Turns out the latest Win 10 update (5th of August) interferes with something related to GPU and game capture as the logs show "successfully capturing d3d9 frames via CPU" even when it says NVENC loaded earlier on. After some trial and error with help from Itazuraa, we decided to uninstall the latest update from Win 10 and my problem is solved. Without this update I would stream CSGO at a steady 300 ingame fps, and with the update installed I could barely get 150 and it felt really choppy.

Anyways, just wanted to post it here in case others have noticed some overnight performance drop when streaming.

The issue seems to be the Game Capture and not NVENC.

AFAIK @Jim needs to apply patches for DirectX because otherwise he can't capture via the GPU.
When Microsoft updates the dlls of DirectX the Patches become invalid and no longer works.

Same is happening for me btw. after updating without NVENC (well can't speak for performance right now because I have only 2 games installed right now).

In the log file it says capturing via CPU instead of GPU.

Jim already added those fixes in 0.654b, or did MS update the dlls yet again.
BTW, my logs always say capturing via CPU, without the update.

There was an Update for Win 10 Osiris which made the patches invalid.
Jim confirmed this to me on IRC.

Cumulative Update for Windows 10 for x64-based Systems (KB3081424)

Yup. Very similar to what happened prior with game capture only not as bad. Some performance lost about half with game capture. Monitor capture still a viable backup for those using window capture. I wonder if they are intentionally doing this to make people use GameDVR :P

Hey Dogfish i was just wondering if you were ever able to get this issue resolved? While running 8.1 i was able to stream beautifully and now with 10 my quality has plummeted. any tips will help thanks

Hey there, I just found this topic, I have windows 10 pro x64, latest and greatest updates, latest and greates nvidia drivers (355.82). I tried making a video today (BF3) since last time (last video was on 8.1) and my last video was superb and smooth (using nvenc, same settings as today).
https://www.youtube.com/watch?v=kMb2NMKzxbw this is the recording on Windows 8.1, you can play it 1080p@60 and u notice the smoothness.

Than today I tried on Windows 10 and this is what i got https://www.youtube.com/watch?v=_L3HkqYTosM
notice how jerky it is? Notice how the handcam is smooth compared to the game.

This is the log. Don't know if it can give you a clue of what im doing wrong. I tried different nvenc preset, with all the same results.

PS: Just some other details. I tried shadowplay (lack of webcam thou) and the video is smooth as the famas video I uploaded while on windows 8.1. Tried OBS with x264 superfast and the video is smooth so it is definitely something with the gamecapture and NVENC.

PS2: just tried Action! the trial. NVENC is working properly. But i cant flip the webcam, etc...I want my working NVENC on OBS!!!! Any help?

Did you ever get this resolved? I am in the same boat. However I use x264 not NVENC. Is NVENC better?
