These modpacks are a lot of things. Whether its the mod known as Entropy, with its raining arrows and teleports that will leave you stranded, or things like Crawl to reach those low places you couldn't before! You can also see 10x further with the Logical Zoom Mod as well!
You can turn on shaders with the Iris Mod and see the beautiful sunset with as much fps as you can handle with the Sodium mod installed to.
*Note, all settings and controls can be configured in each of the settings tabs.
