My system:
i7 4930k
Nvidia GTX 770
32 GB RAM
I get the massive lagged frames due to rendering lag/stalls: 186 (65.0%) - see log below. I'm using the record feature, not streaming.
I'm only recording an idle W7 desktop and some notepad text. The CPU is at about 10% workrate when recording, the GPU is at 35-40% workload (in Afterburner). Still I get only ~18 fps. I've tried x264 and NVENC as well as various bit rates (from 200 to 20000) but little changes. Changing the priority and/or number of threads for OBS to use doesn't change anything, either.
Is this expected behavior? What kind of GPU/CPU would it take to record my desktop at 60fps in 1080p?
