OpenGL
Change OpenGL options that affect performance and image quality.
If On, 32 bit textures will automatically be converted to 16 bit textures. This can improve performance and save memory if a large number of textures are being used.
Multitexturing can improve performance and appearance by allowing more textures to be applied to animated scenes. Turn Off if scenes that use multitexturing do not render correctly.
On boards that support multiple rasterizers, turn On to allow sharing the textures between the raterizers. This can improve performance by increasing the number of resident textures when very large textures are being used. Leave Off for the best performance in most situations.
Turn On to do accumulation in software, and disable the hardware accumulation buffer. Leave Off to allow hardware accumulation if available. Using software accumulation can save the amount of memory that has to be allocated on the card, but the rendering performance to the accumulation buffers will decrease if software accumulation is used. The performance of rendering to other buffers is not affected by this option.
Adjusts the number of samples in multisampling visuals. If Off, multisampling is disabled and no multisample visuals are available. If set to 2X, 4X, or 8X, then multisampling is enabled with the respective number of samples. If multisampling is not possible in hardware, then supersampling is used instead. The driver might disable multisampling if the amount of memory is insufficient to acheive the number of specified samples, or if supersampling is not supported. You must restart Accelerated-X for the changes to take effect.
Enable stereo viewing with VESA compliant stereo glasses. This option takes effect the next time Accelerated-X starts. This option is available on graphics boards that support stereo rendering.
