FPS Packet Burst, Ping Jitter & Router Bufferbloat Optimizer (2026)
Calculate tick-rate desync, bufferbloat jitter amplitude, SQM/CAKE router bandwidth caps, and non-fragmenting MTU settings for Call of Duty: Black Ops 7, Warzone, Valorant, CS2, and Apex Legends.
Packet Burst & Jitter Fix: In 60Hz–128Hz competitive shooters, Packet Burst is triggered when UDP tick variance (jitter) exceeds 7.8ms–16.6ms or when background HTTP texture streaming saturates the local NIC queue. To eliminate packet burst permanently: (1) Set in-game On-Demand Texture Streaming to Minimal/Off; (2) Cap router SQM (CAKE / FQ_CoDel) QoS to 85% of upload and 88% of download speed; and (3) Lock IPv4 MTU to 1472–1492 bytes to prevent ISP PPPoE packet fragmentation.
Frequently Asked Questions
What causes packet burst in Call of Duty Black Ops 7 and Warzone even with low ping?
Packet burst occurs when multiple UDP game-state updates arrive bunched together in a single frame rather than evenly spaced at the server tick interval (16.6ms at 60Hz). The 3 primary causes are: (1) In-game On-Demand Texture Streaming competing with UDP packets on the local socket; (2) Router upstream bufferbloat when upload bandwidth is saturated above 85%; and (3) Wi-Fi half-duplex airtime contention.
What is the maximum acceptable ping jitter for 64-tick CS2 and 128-tick Valorant?
At 128Hz (Valorant), the server processes a tick every 7.81 milliseconds; ping jitter exceeding ±3.5ms causes sub-frame interpolation desync and rubberbanding. At 64Hz (CS2 sub-tick), jitter should remain below ±4.5ms.
How do I configure router SQM / QoS to stop gaming ping spikes?
Enable Smart Queue Management (SQM) using the CAKE or FQ_CoDel algorithm on your router and cap both Download and Upload bandwidth to 85%–88% of your ISP speedtest baseline. This prevents your ISP modem FIFO buffer from filling up and eliminates +80ms bufferbloat spikes.
