Code: Warzone Data Packet Surge
Code: Warzone Data Packet Surge
Packet bursts in Warzone are rendering the game unusable. I've looked into various solutions and shared my experiences on the CODWarzone subreddit, but no fixes seem to help. The problem appears as a stuttering effect triggered by an icon showing three orange scores, indicating packet loss. It freezes intermittently—lasting from half a second to several seconds—and occurs multiple times per minute. This disrupts my gameplay, causing me to lose matches before they begin. I've attached my DxDiag file for reference, though I've already gathered the following details: - My internet connection isn't the issue. - My brother plays Warzone in a party and doesn’t face this problem. - After moving houses, I switched networks and still encounter it. - It’s not related to server-side glitches since teammates have similar issues. - A friend with the same motherboard doesn’t have the same problem, suggesting a hardware factor. - I’ve tried all standard troubleshooting steps: editing game files, adjusting adv_options.ini, changing network adapter power settings, adding the tcpnodelay mod, tweaking registry entries, adjusting GPU/CPU settings, etc. - Both repairing and reinstalling the game have been attempted. - The game runs on an SSD drive. I haven’t reinstalled Windows yet, but I’m hesitant to do so. If anyone has suggestions or solutions, please share them. DxDiag.txt
I created an account since my situation matches yours exactly, and I’ve tried every possible fix in the manual. I performed a completely new Windows installation, yet the problem remains, so don’t throw away your effort. I considered it might be related to my CPU because this game is known for heavy CPU usage, so I upgraded from an i5-9600K to an I9-9900K (I plan to further boost all cores to 5GHz). I also replaced the modem and router, and reinstalled the game multiple times. Almost everything is brand new, but nothing seems to resolve this. Other games work fine, but Modern Warfare keeps showing “packet bursting” (three bright orange icons) in every session. Right now, I’m starting to think it could be a faulty netcode or packet loss somewhere between my device and the server that can’t be identified. I’m completely stuck like you. Perhaps we can discuss this together and help the Warzone community find a solution!
For clarity, here’s my PC configuration:
- Aorus Z390 Master Board
- Intel I9-9900K (OC’d) – 5GHz all cores
- Gigabyte RTX 2070 Super Gaming 16x2
- Corsair Vengeance RGB – 3200mhz (XMP enabled)
- Samsung 970 Evo NVMe SSD – 1TB
- Corsair HXi 850W PSU
- Corsair H150i Liquid Cooler – 380mm LG Ultragear 27” (240Hz IPS)
If you have any details about what you tried or want confirmation on a specific fix, feel free to share. I’ve spent three to four months trying various solutions without success.
I was researching last night and noticed much less packet flooding after increasing my RAM paging file size beyond 1.5x (reaching 4x). With 32GB total, my initial is set at 50GB and max at 128GB. The problem wasn’t fully resolved, but it improved noticeably. I’m still seeing some packet bursts, though. I’ve attached graphs from MSI Afterburner, but I’m observing a drop in GPU usage by about half (from 80-90% to 30-40%). This matches the reduction in GPU load. I’m also checking internet stats while gaming to look for packet drops or fragmentation, but no clear link has emerged so far. Every other game runs smoothly, so it’s unlikely my ISP is the issue. Warzone packets often jump between many servers, which could cause random packet backups. Since friends’ connections might take different paths, they might not face the same problem. If I find a real solution, I’ll share it!
Thanks for your response. If anything resolves my problem, I’ll share it here. We’ve all tried many solutions, but none worked. I’m thinking about a Windows reinstall, though @Rocket_Launcha warned against it. I’ll test the paging file ‘fix’ to see if that helps.
Returning to the discussion for future reference, @Rocket_Launcha’s advice to adjust the paging file helped resolve the problem for 98% of cases. I experienced stuttering during at least half of the game, but now it’s mostly smooth unless I play it. I’m still unsure exactly how it worked, so I’ll share my steps. I searched for instructions on modifying paging file settings and discovered a recommendation to disable it entirely. This was incorrect—once I started the game it crashed, even Chrome. If disabling the paging file causes the crash, it might actually indicate the fix will help. After turning it back on, I noticed activity on my E: drive, which is slower storage. When I switched it to system-managed mode on an SSD, I set a custom range. For a 16GB RAM system, a 20GB paging file seems reasonable, with a maximum of around 25GB. Aim for roughly 1.5 times your total RAM capacity (as suggested by @Rocket_Launcha). Ensure your SSD has enough free space. To change these settings, go to Control Panel → System and Security → System → Advanced Settings → Advanced → Performance → Settings → Advanced → Virtual Memory → Change. Under “Disable automatically manage paging file size for all drives,” select your drive, choose “No Paging file,” then set it. When you re-enable, follow the same process but enable paging only on your fastest drive, and restart. This approach resolved my packet loss issue.
It's good to hear the fix helped ease your "packet bursting" problems somewhat. I still experience them occasionally, but not as severely as before. I've observed these bursts often align with spikes and dips in power usage on both my CPU and GPU. This suggests they might be a common issue across games if this is my setup. I'm hoping for a complete solution soon so we can enjoy smooth gameplay every time. Please share any future updates you find useful.
@ArcaPhox , I found another solution that seemed to help mitigate the "packet burst" issues a bit more, Enabling IPv6 . My old router/modem was a Netgear Cv7000v2 and had a terrible interface with minimal advantages for gamers. I recently upgraded to an Asus AX-88U, and did not realize that IPv6 was disabled by default. This obviously needs to be done at the router level as well as on your PC. **Someone can correct me if I am wrong, but I believe most ISP's offer IPv6 capatibility** So I set this up and have been troubleshooting the last couple of days. Played with just IPv4 for multiple games and the "packet bursts" were pretty significant, but wanted to make sure it wasn't just a "good night" for my internet or the servers, which it was not. Once I re-enabled IPv6, the difference was immediately noticeable. I had far less "packet bursting" game to game. As I said before, this helped to mitigate my issues even further, but they still exist. Do not know if this is something you have tried or not, but figured I would just throw it out there to see if it could help ya out. I am no internet guru, and will never claim to be, but I am sure someone will correct me on here if I am wrong. IPv6 is more efficient and able to carry larger data packets across the network. Best analogy I can think of is comparing a standard pick-up truck to a large semi. It is able to carry more per transmission, therefore more efficient at sending and receiving data. Logically, this would make total sense if Warzone has terrible netcode issues, and servers are trying to send too large of packets for standard IPv4 to handle. In theory, this would mean the servers and ISP's are having to handle (receive/send) double the amount of packets when using IPv4 versus IPv6. Plus, this also would be more efficient for Network adapters and CPU's as more information is compiled within each packet, and would not have to wait for another packet to bring the missing data. Who knows, I am not expert in the matter. Give it a try and see what happens! If you have already done so, just let me know and I will continue trying to find a permanent fix.
