Swift

Q: Who made this mod?
A: Back in September 2016, Paint_Ninja came up with the idea and brainstormed with FreneticScribbler to make it a reality. The mod was originally coded and created by FreneticScribbler.

In 2017, the mod was released as an exclusive for CraftMine and became maintained by Paint_Ninja. Since then, Paint_Ninja has been maintaining and adding new features to the mod, but it is still important to acknowledge FreneticScribbler's great work, whom without him, this mod wouldn't exist today.

Q: How can it improve battery life?
A: Similar to the FPS Limiter mod, Swift can be set up to limit framerate when the game window is inactive or minimised. By intentionally capping the framerate to a low value (such as 10fps), the GPU doesn't have to do anywhere near as much work as when the framerate is at a more playable level (such as 60fps), hence it can enter a lower power state which in turn increases battery life.

Unlike the FPS Limiter mod, the checks to determine if the game is minimised or inactive are much simpler and ran much less often, allowing Swift to be more efficient at the cost of not capping the framerate as often.

Q: Does it work with Optifine?
A: Yes! It can also change Optifine settings via Swift profiles.

Q: Does it work with the Shaders mod or Optifine's shaders?
A: Kinda. Swift won't conflict with them, but it can't change shaderpacks or other shader settings at this time. See https://github.com/FreneticScribbler/Swift/issues/8

Q: It crashes my game on launch, what should I do?
A: Make sure the number of triggers match the number of commands and vice-versa. E.g. don't have a trigger for "Under 30fps" without a command and warning for that trigger, even if they are blank you must put something there.

If you're still having trouble, please don't copy and paste the entire crash log into the comments! It'll just become a mess. Upload it to somewhere like pastebin and post the pastebin link in the comments and we'll try to help you out. :)
