OBS has different settings

My friends' OBS has CRF and CPU usage preset while mine doesn't. My OBS has the black theme and his has the gray one.

Change the Video Encoder to x264 for the CPU Usage and CRF options. CRF is a Rate Control option similar to CQP in NVENC.
Settings > General to change the theme.
