===== To SSE2 or not to SSE2? =====

By default, L3DT Pro uses a version if this plugin that was compiled to use //[[wp>SSE2]]// optimisations to accelerate the DXT1 compression algorithm. These extensions make SMT writing at least 10x faster, but are **only compatible** with the following processor lines:
  * Intel P4 or later.
  * AMD Athlon64 or later.

If you are using an older processor, the SSE2-optimised plugin will **probably crash** (:!:). To switch to the un-optimised plugin, open the extension manager ('//Extensions->Extension manager//' in menu), disable the 'L3DTio_SMT_SSE2' plugin, and enable the 'L3DTio_SMT' plugin. On restart, L3DT will use the un-optimised plugin.

===== Notes =====

<note important>
This plugin is the back-end for the main Spring plugin ([[plugins:fileio:L3DTio_Spring]]), and has no user interface or options. To load/save SMT files, you must use [[plugins:fileio:L3DTio_Spring]].
</note>

<note>
This plugin uses the [[http://sjbrown.co.uk/?code=squish|Squish]] library by Simon Brown for DXT1 compression/decompression.

Many thanks go to Tobi Vollebregt for assistance with decoding the SMT format.
