Network instability in ARC Raiders can cause missed shots, delayed hit confirmation, positional desync, rubber-banding, and sluggish combat responsiveness. These issues are almost always tied to ping variance, packet loss, server distance, or CPU/GPU load affecting network threads.
Below are the most reliable, practical fixes to improve live synchronization, reduce lag, and tighten hit-registration timing during raids.
Use a Wired Connection Instead of Wi-Fi
Ethernet drastically reduces:
- packet drops
- latency fluctuations
- micro-lag during combat
ARC Raiders is sensitive to micro loss even if your ping looks stable. A wired connection immediately improves consistency.
Close Bandwidth-Heavy Background Processes
Shut down anything that competes with ARC Raiders for bandwidth:
- browsers streaming media
- game launchers updating
- cloud backup tools
- VPNs
- large downloads
Bad timing during a raid equals delayed hit registration.
Select the Nearest Server Region
If the game auto-routes you to the wrong server region, ping can spike.
Always pick:
- the closest server
- the lowest latency value shown
This is one of the simplest and most effective fixes.
Set Windows to High Performance Mode
Windows sometimes prioritizes background tasks over live game threads.
Switching to High Performance:
- stabilizes CPU responsiveness
- prevents network thread throttling
- reduces combat desync moments
Disable Windows Network Throttling
Some Windows versions apply multimedia prioritization that disrupts live packet handling.
Turning this off improves:
- hit-confirmation timing
- packet refresh
- overall responsiveness

Avoid VPNs and Proxy Tunnels
These add:
- distance to routing
- encryption delays
- unstable packet paths
If you absolutely must use one, choose the closest exit node to your physical region.
Enable QoS Priority on Your Router
If supported:
- give ARC Raiders high traffic priority
- mark your PC as the primary device
This ensures local devices can’t “steal” bandwidth mid-fight.
Enable NVIDIA Low-Latency Mode
With NVIDIA GPUs, Low-Latency Mode improves frame pacing.
Cleaner frame timing gives the server a more predictable window to validate hits.
Cap Your FPS to Prevent Network Thread Starvation
When the GPU is maxed out, network processing can fall out of sync.
Capping FPS stabilizes system load and improves packet scheduling.
Suggested caps:
- 75–120 FPS depending on system strength
Use Bufferbloat Control (If Router Supports It)
Routers handling heavy internal traffic can delay outbound packets.
Bufferbloat controls:
- prevent ping spikes
- lock combat packets at priority
- reduce ghost-shot desync
Switch DNS to a Faster Resolver
DNS doesn’t control hit registration directly, but a faster resolver makes:
- server assignment cleaner
- session handshake more stable
- connection recovery faster
Cloudflare and Google DNS are common picks.
Test for Packet Loss (Critical)
Hit-reg issues are most often caused by packet loss — even a tiny amount.
If testing tools show loss:
- reboot router
- switch ports
- isolate cable
- elevate Ethernet line
- contact ISP if consistent
1–2% packet drop is enough to cause delayed hit confirmation.
Disable Cross-Play (If Supported)
Cross-play often mixes routing clusters and wider player pools.
Sticking to your own region typically cuts latency windows and stabilizes hit timing.
Verify Game Files
Corrupted network-related assets can cause:
- delayed server responses
- unsafe phase transitions
- sync stalls
Run file integrity check through Steam or launcher.
Reduce System Load to Improve Sync Stability
High GPU/CPU consumption reduces available cycles for real-time network threads.
Turn down:
- volumetric lighting
- shadow quality
- model detail
- post-processing
- high-resolution textures
If your raids crash only during huge ARC fights, this is the fix.
Restart the Game Between Long Sessions
ARC Raiders can build memory pressure after long play sessions, causing:
- lag spikes
- hit-delay moments
- sync interruptions
A simple restart refreshes the connection stream.
Reboot Your Router to Clear Routing Cache
Routers accumulate stale routing assignments.
A restart:
- resets connection paths
- improves packet alignment
- resolves weird sync issues in raids
Keep Ping Under 60ms
The game begins to show noticeable desync in the 70–90ms range.
If ping is consistently high:
- confirm correct region
- switch to wired
- reduce home network load
Avoid Raiding on Congested Networks
If multiple people are streaming, downloading, updating OS builds, or syncing drives, ARC Raiders traffic will suffer.
Keep the network as clean as possible during raids.
Quick Fix Checklist
✔ Wired instead of Wi-Fi
✔ Server set to nearest region
✔ All bandwidth-hungry apps closed
✔ VPN/proxies disabled
✔ Router QoS enabled
✔ NVIDIA Low-Latency Mode on
✔ FPS capped
✔ DNS switched
✔ Verified game files
✔ Restart router if packet loss
✔ Lower GPU load for cleaner sync
✔ Restart game on long sessions
Most players find the fix within the first 5 items.
Final Takeaway
ARC Raiders’ hit registration and network performance depend mostly on:
- stable ping
- no packet loss
- clear routing paths
- low system overhead
- closest server region
- steady frame pacing
When the connection is consistent, hits confirm faster, combat feels immediate, and enemy tracking lines up cleanly.
