Recurring Lag Spikes/Freezes in HotS and StarCraft 2 Despite Good Performance and Connection

Hello,

Over the past two days, I’ve been experiencing recurring, short lag spikes (lasting 2–4 seconds) during gameplay—and even in the menus—in both Heroes of the Storm and StarCraft 2 on the EU server. This issue occurs despite having a stable internet connection and no unusual system activity at the time of the lag.

System performance during the spikes:

Latency: <5 ms

CPU usage: <20%

RAM usage: <40%

Interestingly, I don’t encounter any similar issues when playing Age of Empires, which has higher system requirements. This suggests the problem may not be hardware-related.

Has anyone else experienced similar issues or found a potential cause or solution? Could this be related to Blizzard’s servers?

Thanks in advance for any insights.
