Looking at your logfile you are enforcing multi-adapter compatibility, which uses system RAM, in your game capture source options (Click on the little cogwheel for the Game Capture source) can you un-check multi-adapter compatibility, direct hooking method is far more efficient to grab frames to record/stream.
As for the error:
01:55:44.588: socket_thread_windows: Received FD_CLOSE, 53223 ms since last send (buffer: 400486 / 404480)
01:55:44.588: socket_thread_windows: Aborting due to FD_CLOSE, error 10053
That is a data send timeout error, possibly modem/router, ISP, your PC network configuration.
