G1ax Crystal Optimizer
by tech.anupam
G1ax Crystal Optimizer is a Fabric client mod that reduces the local delay when end crystals are placed and broken in Crystal PvP.
What it does
The mod changes how the client handles end crystal placement and breaking. Processing happens on the player's own machine, so the visible result of an action arrives sooner, which is meant to make crystal fights feel more responsive on multiplayer servers, including connections with higher ping.
Several optimization modes are available, and the mod can adapt its processing to the measured latency. It predicts crystal state on the client so the screen reacts before the server confirms the change. Because the mod is client-side only, servers run without installing anything and players connect without it.
Installation needs Fabric. Files are published for Fabric and Legacy Fabric, with the latest Fabric build 1.0.7 for 26.3 and the latest Legacy Fabric build 1.0.6 for 26.2. The code is open source under the MIT License.
Key features
Faster crystal placement
End crystals appear on screen with less delay after the player places them.
Faster crystal breaking
Breaking a crystal is reflected on the client sooner, reducing the wait before the next action.
Client-side crystal prediction
The client predicts crystal changes ahead of server confirmation to lower perceived lag.
Adaptive latency handling
Optimization adjusts based on measured latency, and several modes can be selected to suit the connection.
