A 30-second aim test with one cruel twist: your shots land late — while the target keeps moving. Exactly like playing on high ping.
You click instantly — but the shot only lands after the delay, and the target never stops moving. That's not a bug. That's a Tuesday on 300 ping.
A lag simulator adds artificial delay to your actions, so you can feel in your own hands what a game plays like at 50, 100 or 300 ms of ping. This one runs entirely in your browser — no download, no sign-up. Set the lag anywhere from 0 to 500 ms and your shots in the 30-second target range land that many milliseconds late, while the targets keep moving.
The quickest way to use it: run 0 ms first for a clean baseline, then repeat at 100 ms and 200 ms. The verdict compares the same pair of hands at different delays, so the accuracy you lose is the lag's doing, not yours. It is also the fastest way to settle gaming's oldest argument — 'the lag' versus 'you're just bad' — with numbers instead of feelings.
One honest limit: this simulator reproduces the effect of latency on your aim by delaying your shots locally. It does not change your connection, and it does not measure it. To find out what your ping actually is, run the pre-game network check; if the real thing feels worse than it should, the Lag Clinic works out why; and if lag really did cost you the game, claim your Certificate of Innocence.
