Default Re: Does 90 Rotated display have hardware acceleration?

Per the driver REAMDE:

Option "Rotate" "string"

Enable static rotation support. Unlike the RandRRotation option above,
this option takes effect as soon as the X server is started and will work
with older versions of X. This feature is supported on GeForce2 or better
hardware using depth 24. This feature does not work with hardware
overlays, and emulated overlays will be used instead at a substantial
performance penalty. This option is not compatible with the RandR
extension. Valid rotations are "normal", "left", "inverted", and "right".
Default: off.


Option "RandRRotation" "boolean"

Enable rotation support for the XRandR extension. This allows use of the
XRandR X server extension for configuring the screen orientation through
rotation. This feature is supported on GeForce2 or better hardware using
depth 24. This requires an X.Org X 6.8.1 or newer X server. This feature
does not work with hardware overlays, and emulated overlays will be used
instead at a substantial performance penalty. See Appendix U for details.
Default: off.
