Basically, some Windows systems were crashing when Tor Browser had
hardware acceleration enabled.

I think we made that change in TBB 3.5rc1:

See the (alas not labelled with a ticket number) line:
"Misc Prefs: Disable layer acceleration to avoid crashes on Windows"

It looks from the various tickets like the issue is not entirely sorted
for all users.

Be careful! I think you asked here about hardware acceleration in Tor
Browser, aka our Firefox fork, but the man page you're quoting is for
the program called tor.
