Comment 2 for bug 1280938

I suspect 1920x1200x60 FPS is more bandwidth than my SSD has. It would need 553 MB/s writing, which it certainly can't. So I wouldn't expect it to keep up. But I think it would be nice to just degrade the screencasting frame rate (drop frames from the recording but not the actual screen).

Tested on amd64 with Intel i7-4770 (Haswell). It's a fast machine, but the SSD is pretty average: Samsung PM830 (max write speed 400 MB/s, likely less).
