Default: XVideo is enabled for configurations where it is supported.
.TP
.BI "Option \*qLegacy3D\*q \*q" boolean \*q
Enable support for the legacy i915_dri.so 3D driver.
This will, among other things, make the 2D driver tell libGL to
load the 3D driver i915_dri.so instead of the newer i915tex_dri.so.
This option is only used for chipsets in the range i830-i945.
Default for i830-i945 series: Enabled.
Default for i810: The option is not used.
Default for i965: The option is always true.
.TP
.BI "Option \*qAperTexSize\*q \*q" integer \*q
Give the size in kiB of the AGP aperture area that is reserved for the
DRM memory manager present in i915 drm from version 1.7.0 and upwards,
and that is used with the 3D driver in Mesa from version 6.5.2 and
upwards. If the size is set too high to make room for pre-allocated
VideoRam, the driver will try to reduce it automatically. If you use only
older Mesa or DRM versions, you may set this value to zero, and
activate the legacy texture pool (see
.B "Option \*qLegacy3D\*q"
). If you run 3D programs with large texture memory requirements, you might
gain some performance by increasing this value.
Default: 32768.
.TP
Enable support for the non-GEM mode of the 3D driver on i830 and newer.
This will allocate a large static area for older Mesa to use for its texture
pool. On systems with a working GEM environment, this can be disabled to
increase the memory pool available to other graphics tasks.
Default for i830 and newer: Enabled.
Default for i810: this option is not used.
.BI "Option \*qPageFlip\*q \*q" boolean \*q
Enable support for page flipping. This should improve 3D performance at the
potential cost of worse performance with mixed 2D/3D. Also note that this gives
