What is Quasar?
Quasar is a custom Minecraft 1.8.9 client for competitive PvP. Instead of bolting on a mod, Quasar edits Minecraft's own classes at load time with SpongePowered Mixin, so it runs as a standalone client - not a Forge or Fabric add-on. It is free to use.
Tighter networking
Quasar tunes the connection and trims the packet path to cut client-side delay.
Smart culling
The renderer only draws what your camera can see, which frees frames for the fights.
An honest note on ping
Quasar cannot lower your physical network ping - no client can. What it can do is tighten everything the client controls and add high-ping feel features, like ping-adaptive movement prediction and smooth rubber-band correction, so a far server feels closer than the raw number suggests.
What makes it different
- A glassmorphism custom UI and configurable HUD.
- A latency-tuning and prediction suite built for high-ping play.
- An in-client Modrinth resource-pack browser.
- Auto-Tune on join and Smart Armour, among other quality-of-life tools.

1.8.9 only for now - the version the competitive scene still plays. Built and run on JDK 8. More versions are a possible future expansion, not a promise.
