V-Rising Simulation Time Desync Fix for Dedicated Server

V-Rising Simulation Time Desync Fix for Dedicated Server

As layers progress into the late-game of V-Rising, the number of active entities—from castle servants to complex industrial machines—can cause the dedicated server simulation to fall behind the client's clock. This results in "Ghost Hits" during combat or servants appearing to teleport. This guide covers how to repair these simulation desync issues.

⏱️ The Simulation Clock

V-Rising runs a internal simulation loop. If this loop takes longer than 33ms (for a 30 FPS server), desync occurs between the server's reality and the player's screen.

🧵 Unity xvfb Overhead

Because the V-Rising server requires a virtual display (xvfb) on Linux, improper X-server configuration is the #1 cause of simulation lag in 2026.

Technical Fixes for Desync

1. Adjust the Matchmaking FPS

By default, many servers are set to 30 FPS. If you have a high-performance host, increasing the MatchmakingFPS in your ServerHostSettings.json can resolve many combat delays by providing a tighter feedback loop.

# ServerHostSettings.json
{
  "MatchmakingFPS": 60,
  "UpdateRate": 60
}

2. Optimize "Service" entities

If your V-Rising dedicated server is lagging specifically in castle-heavy areas, the issue is likely the servant pathfinding logic. To fix this:

  • Limit Servant Count: In ServerGameSettings.json, reduce MaxServantsPerPlayer to 5-7.
  • Simplify Castle Layouts: Encourage players to avoid "Labyrinths" which force the server to calculate complex pathfinding nodes every tick.

3. Real-Time Process Priority (Linux)

Ensure the VRisingServer.exe (running via Wine) has high priority. This prevents the OS from "Parking" the simulation threads during low activity, which causes a spike when a player suddenly engages in boss combat.

# Set nice value to -10
renice -n -10 -p $(pgrep VRisingServer)

Database Tip: Large save files (over 50MB) can cause "Simulation Stalls" during the periodic save. Increase the AutoSaveInterval to 1800 (30 minutes) to minimize these interruptions.

Conquer the night without lag. Rent a V-Rising Server with dedicated threads and pre-optimized Wine environments for high-FPS combat.
