-By default, Nageru uses zerocopy from the GPU to the VA-API buffers in order to
-reduce memory transfer bandwidth, but this depends on EGL support (as opposed to
-the older GLX standard), and also that the GPU you are rendering to also
-supports VA-API. NVIDIA's proprietary drivers do not support either. Unfortunately,
-this is somewhat cumbersome to automatically detect before it's too late to do anything
-about it (Qt has already initialized using EGL), so on NVIDIA
-systems, Nageru will exit with an error message asking you to set *--va-display*
-to your Intel GPU manually. Simply follow the instructions printed to the terminal
-to select what looks like your Intel GPU, and Nageru will fall back to using GLX
-and transferring the memory data between the two GPUs via the CPU. (Some BIOSes
-automatically disable the Intel GPU if you have a discrete GPU installed; you
-will need to reenable it to get access to QSV, or Nageru can't run.)
+(see :doc:`streaming`). You can also use x264 to produce the recording to disk
+instead of Quick Sync, using the --x264-record-video flag. If you wish to have
+separate flags for streaming and storing to disk (e.g., to keep a digital intermediate
+on disk), and have Nageru 2.1.0 or newer, you can use the --separate-x264-disk-encode flag (and associated
+--x264-separate-disk-bitrate flags etc.). Otherwise, the same stream will go
+to the network and to disk.
