Lagspikes
Lagspikes
Consider testing in a more limited offline environment. Have any lag spikes returned? Are mods present? Also, are there other programs running at reduced levels during gameplay, like multiple Chrome windows or security software?
It's feasible to create a more compact environment. You're not using a single-player mode and are already running Chrome tabs, which can help. Since you don’t have antivirus installed, consider testing with a lightweight browser extension or disabling security software temporarily for performance checks. Restarting your PC after a while might resolve lag spikes that appear only after prolonged use.
