Chrono v2¶

Drop-in custom physics replication solution for Roblox!¶

Chrono provides full control over replication and physics while remaining compatible with Roblox’s networking model. It is designed to be drop-in for existing games, with a wide range of configurations allowing for custom characters and more.

Roblox replication "issues" (and what chrono does)¶

1. Fixed replication rate¶

Roblox replication rate is not configurable.

Chrono uses a dynamic tick rate instead with user provided bounds that scale based on proximity.

2. Forced interpolation delay¶

Roblox's interpolation buffer varies between 200-500ms.

Chrono lets the developer control the minimum and maximum delay (or u can use a static delay!). You can introspect it in realtime so lag compensation becomes much nicer.

3. No usable historical state¶

Roblox doesn’t store ur snapshots. Chrono does (and has a built-in lagcomp api using serverclock).

4. Unoptimized af¶

For 150 NPCs moving randomly:

• roblox used 110.29 kb/s send and 412 kb/s receive.
• chrono used 3.72 kb/s send and 42.97 kb/s receive
