Hi, OBS is awesome when recording with x264 (too high cpu usage in some games like WoW or Final Fantasy XIV though), but when I try to use Quick Sync to record some games, a red warning message appears on the bottom of the obs window, telling me that cpu encoding usage is too high, but even if I try recording at 3500 kbs CBR the message appears in high-motion scenes. The result is an extremely laggy video. The log i put down there is a test done while recording a benchmark in Just Cause 2, @1080p60fps 50mbs
My pc specs:
CPU - i7 4770
GPU - GTX 780 DirectCU II
RAM - 16 GB
OBS installed on a SSD and recording on a HDD
