Unusual latency spike following GPU upgrade
Unusual latency spike following GPU upgrade
I upgraded to a newer GPU after my old one stopped working. My CPU is still slower, so I’m thinking about replacing it soon. I installed the new GPU and drivers through GeForce Experience, and game ping was okay except for some odd lag spikes. I tried cleaning up the driver setup with DDU, but now I’m experiencing steady high ping or latency instead of just occasional spikes. I followed various network troubleshooting steps—my internet is fine otherwise—and kept everything updated, including BIOS, but the problem persists. I suspected a CPU/GPU bottleneck because the GPU seems too advanced, but someone said it’s probably just a network issue. I’m confused and getting mixed messages online.
It could be unrelated, but it’s worth checking. Your slow online performance might point to your internet service or network settings rather than your GPU. Focus on improving your connection quality for gaming and other online activities.
Are you connected via Wi-Fi or LAN? Please share your motherboard and PSU model.
Possibility one: Issues similar to these were common a long time ago. Low-quality boards or worn capacitors can lead to strange behavior with Wi-Fi and high-power devices. These problems used to be frequent around two decades ago, but they’re rare now.
Possibility two: Background processes like a game or app are consuming bandwidth, leading to lag.
Possibility three: A new GPU is drawing excessive power, stressing the PSU and potentially causing unstable voltage or EMI, resulting in performance issues.
There might be a problem, but it seems to be more than just a high ping. Issues like dropped connections and big lag spikes are happening. It could just be a random occurrence. Restarting your modem or router should definitely help.
wifi increases the chance of possibility3. If the GPU also has coil whine problems, this is likely the cause. Test with an ethernet jack to see if it helps. This should help determine whether the issue is wifi interference or a network card problem. I’d move the wifi antenna slightly and check the cable from the wall to the power supply—EMI could be involved. Adjust its position. Also, the cable could cause interference. You might want to bring a friend over; if they experience lag on your network, it could be someone nearby using a microwave or having interest in signal jamming tech, maybe even building gadgets in their garage.
I switched my router on and linked my PC via Ethernet, but the connection still isn't working. I suspect the problem lies with the game server itself rather than the network setup, since my ping is normal for other games and online tests are passing. It's odd that this started after the recent upgrade and update.
We realize it's not Wi-Fi. If you're confident it's just one game with increased latency, the issue is probably on the server side. Businesses often relocate servers at times. For example, when Rito moved the League of Legends server, my ping almost doubled in a short period.
