IFL Turbo is a 3ds Max plugin that delivers super charged viewport Image File List (IFL) playback.  Performance is generally 3-8x faster than MAX's native playback, particularly for high resolution images or files residing on network drives.

The plugin works on IFL files containing any frame sequence (jpg, png, etc) and caches the frames in RAM for fast (relatime) playback.  The images can be optionally resized to reduce memory footprint and further improved performance.
The plugin is a drop in replacement for the existing IFL handler provided within MAX.   Files from or sent to other computers with IFL sequences will work as before (albeit without the advantage of improved performance).
