Krypton Reno

Since we no longer provide Forge compatibility starting from version 26.1, the original name “Krypton FNP” is no longer meaningful.<\/p>\n
The acronym “FNP” stood for “Forge and NeoForge’s Port,” but as Forge support is now absent, I have renamed this mod to Krypton Reno.<\/p>\n
To ensure that our legacy URLs cannot be exploited by malicious parties, the URLs for our listings on Modrinth and CurseForge will remain unchanged, only the URL for the GitHub repository has been updated.<\/p>\n

Krypton Reno provides powerful network optimization capabilities for all major systems.<\/p>\n
Ported from Krypton Fabric, with some unique optimizations added. Supports NeoForge\/Forge; <\/p>\n
For Fabric\/Paper Server, please see the KryptonReno Fabric<\/p>\n
For Velocity Server, please see the VelocityNT Recast.<\/p>\n
—<\/p>\n
## Differentiation<\/p>\n
> This refers to the differences between “us” and upstream “Krypton Fabric” and other Krypton Forks<\/p>\n
– Continuously provide compatibility for stable versions (1.20.1, 1.21.1) and the latest versions
\n– RecastLib provides acceleration features for **Windows** (x64\/arm64)
\n– Further scalability optimizations<\/p>\n
## What is RecastLib<\/p>\n
RecastLib is a native library I wrote in Rust that is compatible with Velocity Native JNI Bind.<\/p>\n
It aims to make up for some of the shortcomings of Velocity Native compatibility,
\nthereby making the performance advantages of KryptonReno more comprehensive.<\/p>\n
In KryptonReno for Fabric, I\u2019m also testing the stability of the FFM APIs available in Java 22,
\nwhich, according to benchmarks, should provide more performance gains
\n(ultimately Fabric only. Forge\/NeoForge won\u2019t be able to run them).<\/p>\n
Their benefits are obvious that both Server and Client can benefit, and that most popular PCs can run these native
\nlibraries due to the replacement compatibility.<\/p>\n
### Compatibility<\/p>\n
| System & Arch | RecastLib | Velocity Native |
\n|—————————–|———–|—————–|
\n| Windows x64 | Yes | No |
\n| Windows arm64 | Yes | No |
\n| Linux x64 | No | Yes |
\n| Linux arm64 | No | Yes |
\n| MacOS arm64 (Apple Silicon) | No | Yes |<\/p>\n
**Compatibility is “hybrid”; they provide compatibility in areas where the other does not support them,
\nso you don’t need to worry about losing compatibility.**<\/p>\n
Currently, there are no plans to provide compatibility for Android,
\n32-bit architecture operating systems, or other architectures.<\/p>\n
Please do not open any related issues or complain to me,
\neven if you do, I can’t help.<\/p>\n

## Benchmark<\/p>\n
<\/p>\n
## Q&A<\/p>\n
### 1<\/p>\n
**Q:** If I install this mod on the client but not on the server, will I be unable to join the server?<\/p>\n
**A:** I deliberately designed it to be “consistent” with Krypton Fabric, so you can connect (be connected to) even if
\nthe
\nother end doesn’t have this mod, unless the server administrator has installed an anti-cheat mod that detects the mod
\nlist, in which case you should contact them to request permission.<\/p>\n
—-<\/p>\n
### 2<\/p>\n
**Q:** Will it help me reduce ping latency?<\/p>\n
**A:** Krypton Reno’s optimizations can save some hardware performance, which should reduce high latency caused by CPU
\ncore
\npreemption. However, if your hardware resources are already very limited, or your network quality is truly poor, then
\nKrypton Reno can’t save you much. It can’t push the physical limits.<\/p>\n
—-<\/p>\n
### 3<\/p>\n
**Q:** Which mods is Krypton Reno compatible with?<\/p>\n
**A:** There are a lot! You basically only need to worry about whether they will conflict with each other, without
\nhaving to
\nworry about Krypton Reno.<\/p>\n
Incompatible Mods: Krypton Reforged, Ceres, Pluto, KryptonFoxified, Chionanthus, Krypton Fabric with Connector<\/p>\n
—-<\/p>\n
### 4<\/p>\n
**Q:** Will it cause some different behavior?<\/p>\n
**A:** This is unavoidable, I have tried to keep the implementation as aligned as possible, and in most cases you only
\nneed
\nto modify the configuration to continue using it.<\/p>\n
—-<\/p>\n
### 5<\/p>\n
**Q:** Can I use Krypton Reno in servers that mix Bukkit API with Forge\/NeoForge?<\/p>\n
**A:** No, absolutely not. The Bukkit API was simply not designed to support Mods, and I can’t guarantee that Krypton
\nFNP won’t break something there, or that they break Krypton FNP.<\/p>\n
—-<\/p>\n
### 6<\/p>\n
**Q:** I can’t seem to load the native library (Velocity Native or RecastLib), what should I do?<\/p>\n
**A:** Generally, this should be caused by missing dependent libraries on the machine.<\/p>\n
– For Windows: You should probably
\n install MSVC 170
\n and OpenSSL 3 Win32
\n– For Linux: You should have at least OpenSSL3 installed (most operating systems should come with it)
\n– For MacOS: You should do nothing, just make sure the system is up to date.<\/p>\n
These libraries should be compatible with x64 and arm64 architectures, so you don\u2019t need to worry about them.<\/p>\n
—-<\/p>\n
### 7<\/p>\n
**Q:** Is the fork of KryptonFNP\/Krypton Reno better than the original?<\/p>\n
**A:** Don’t ask me this question. There are already so-called “fork users” causing trouble in my Issues and insulting
\nmy mod as a “garbage mod”.<\/p>\n
—-<\/p>\n
### 8<\/p>\n
**Q:** I want to create a mod that competes with KryptonReno\/Krypton Fabric. Is that possible?<\/p>\n
**A:** I won’t stop you from doing this, but some authors might not like it. We haven’t stopped updating, yet you’re
\ncompeting with us using the same loader, the same codebase, and the same version, and you’ve removed us from the author
\nlist\u2014that’s not good.<\/p>\n
