# Respackopts
\n**PSA:** Respackopts depends on LibJF, which you must add alongside it.<\/p>\n

Respackopts provides resource and data packs with config menus
\nBy default, it provides a custom system for conditional resources, resource expansion and integrates with fabulous shaders<\/p>\n

## Using Respackopts
\n### Users
\nAfter installing Respackopts, a menu button will appear besides all supported resource packs.
\nNo further configuration is needed.<\/p>\n

### Pack authors
\nPlease head to the wiki for details on how to use Respackopts in a pack.<\/p>\n

# Performance Impact
\nPerformance always depends on factors other than the game itself like disk speed, resource usage by other programs, the OS you are using, etc.
\nThese measurements were taken with Minecraft 1.20.1, Fabric Loader 0.14.21, Fabric API 0.84.0, LibJF 3.8.0 and
\nTherefore, please do not assume these measurements to be accurate for all use cases.<\/p>\n

LibJF injects hooks into the resource loader, meaning there is additional overhead for every resource access.
\nIn practice, this results in a five percent increase in resource reloading time over vanilla and an eight percent increase in game load times over vanilla (.2 seconds).<\/p>\n

Respackopts uses those hooks and additional mixins to work, adding additional overhead.
\nIn practice, this results in a six percent increase in resource reloading time over vanilla and an eighteen percent increase in game load times over vanilla (.43 seconds).<\/p>\n

The most significant increase is measurable during pack scanning, which takes nearly 100 times longer when comparing Minecraft with Respackopts to vanilla.
\nThis is because Respackopts performs and caches most parsing and computation during this stage.
\nAs the statistic for game loading shows, this is not necessarily noticeable during startup, because the total is still comparably small.
\nIt is only noticeable in the resource pack screen, where scanning is performed every 20 ticks and whenever the screen is resized and the impact is much larger.
\nFor this reason, I have created a separate mod that tweaks that screen for increased performance.<\/p>\n
