I experienced occasional 0.5 - 1 sec lag once couple hours for long time, although one version of Squad, I think it was v12, I didn't have any at all.
Recently (it feels like after Nvidia drivers / Geforce Experience update) it became worse and I get it quite often, once 5 minutes. During the lag memory hard faults jump for 100/sec, which is my main suspicion right now. Any ways to further test or fix? Squad is on SSD. I do not use page file.
