# Tools & Features

- [4K Streaming](https://guide.ci.me/en/viewer-guide/tools-and-features/4k-streaming.md): CI.ME 4K playback uses up to 35 Mbps, so 150 Mbps or more is advised. If buffering persists, move to wired or 5 GHz Wi-Fi, then drop quality to 1080p.
- [Chat Features & Badges](https://guide.ci.me/en/viewer-guide/tools-and-features/chat-features-and-badges.md): How chat badges work on CI.ME: the difference between subscriber, channel, and role badges, plus the Founder's Badge for a channel's earliest fans.
- [About Badges](https://guide.ci.me/en/viewer-guide/tools-and-features/chat-features-and-badges/about-badges.md): CI.ME badges come in subscriber, channel, and role types. Up to four show beside your name, role badges first, and channel badges appear only where earned.
- [Founder's Badge](https://guide.ci.me/en/viewer-guide/tools-and-features/chat-features-and-badges/founders-badge.md): Subscribe before a CI.ME streamer's first broadcast or within 30 days of it to earn the Founder's Badge. It is unlimited and permanent, but lost on refund.
- [Inappropriate Language](https://guide.ci.me/en/viewer-guide/tools-and-features/inappropriate-language.md): CI.ME's profanity filter masks explicit words with asterisks or blocks the message, and is tuned so everyday expressions are not caught by mistake.
- [About Drops](https://guide.ci.me/en/viewer-guide/tools-and-features/about-drops.md): Watch CI.ME streams carrying the Drops tag for the required time to earn in-game items or coupons, then claim them from My Page under Drops Inventory.
