Full network + PC diagnostic support.
Fortnite, League of Legends, Counter-Strike, rFactor2, and Assetto Corsa Competizione are on the roadmap — tell us which you'd like prioritized via the feedback page.
Not just a ping test — a full diagnostic across everything that can cause lag.
Real packet capture during your session — jitter, dropped packets, and hop-by-hop tracing to your router and ISP.
Confirms you're connected to the right iRacing farm and flags if your route isn't optimal.
Power plan, network adapter power saving, GPU driver age, background CPU load — the settings that cause stutter that isn't your network's fault.
Cross-references iRacing's own service status and AWS infrastructure health, so you know if it's not you at all.
Detects your ISP and shows how it typically performs for gaming, based on independent broadband reviews.
No raw numbers dump — a written diagnosis explaining what's wrong and exactly how to fix it.
LagInspector is in open community beta right now, across iRacing, Le Mans Ultimate, and Rocket League. We've released 200 codes — first come, first served — and every bit of feedback from testers directly shapes what gets built next.
