Fix lag and rubber-banding in Fragpunk

December 21, 2025 · 6 min read

We measured this on mid and high-end rigs running Fragpunk and only kept the tweaks that moved 1% lows, not just the average FPS counter. Here's what survived testing.

Tighten the network path

Ping spikes and packet loss read as 'lag' but feel like death-behind-walls in Fragpunk. Wired beats wireless every time for consistency.

Use Ethernet, pick the closest reliable server region, and enable QoS on your router to prioritise game traffic over downloads on the same line.

  • Ethernet over Wi-Fi (or 5GHz + DFS channel if you must)
  • Closest stable server region, not just lowest ping
  • Router QoS / gaming mode prioritising your PC
  • Disable background updates and cloud sync while playing

Start with a clean Windows baseline

The single biggest source of stutter we see is the OS scheduling background work during gameplay. Lock that down first and every later tweak gets more stable.

Set the power plan to High Performance (or Ultimate), disable startup apps you don't need, and turn off Memory Integrity if you're chasing every last frame — re-test after each change.

  • Power plan → High Performance / Ultimate
  • Disable non-essential startup apps in Task Manager
  • Turn off Game Bar + background recording
  • Set Graphics preference → High Performance for the game's .exe
// The TL;DR
  • Ethernet over Wi-Fi (or 5GHz + DFS channel if you must)
  • Power plan → High Performance / Ultimate
