OTOY Forums

I´m currently using OBS (Open Broadcaster) for capturing my videos. I want to capture at 60 fps, so I enable the NVENC server as the capture method into OBS, but I´ve found that when trying to capture a working session with Octane, the image freezes (in the captured video, not in the session) and returns after a couple of seconds. This happens when trying to rotate the view into Octane, zooming, or whatever I do involving the graphics card to start rendering.I guess the power of the graphics card goes to Octane 100% then returns to OBS, causing the freeze.
Is there anything I can do to let my graphics card work well with OBS (using the NVENC capture server) while using Octane without any lag like the mentioned above?

Have you tried turning off the OpenGl viewport in Preferences->Application->Veiwport?

I´ve just tried that. No luck.

I also tried to disable one of the two cards (gtx690) in the cuda devices and same results.

This happens because Octane maxes out the GPU cores and the NvFBC priority is lowered. Unfortunately there's no work around except to use a different capture method. If you're on Windows 8+ I'd recommend looking at DXGI capture, or short of that GDI capture.

I tested a bunch of programs a while back and use VirtualDub
(OpenSource, CPU, lightweight)

Open the Program
Click File Menu / Capture AVI (brings up a new window)
Click File Menu / Set Capture File (anyname.avi)
Click Device Menu / 0 Screen Capture
Click Capture Menu / <edit any settings>
