Average FPS is a lie.
You can be sitting at 120 FPS average and still feel stutters and frame drops constantly. That's because average FPS hides your worst frames — the spikes that actually make the game feel bad.
1% lows show you the bottom 1% of your frame times averaged over a rolling window. If that number is tanking while your average looks fine, you've found your problem.
I built FPS Overlay to surface the metrics that actually matter for diagnosing performance:
- 1% Low FPS — the stutter detector
- TPS — is the server keeping up? 20 = healthy, anything lower = lag
- MSPT — how long each server tick takes. Above 50ms and the server is struggling
- FPS + Avg FPS + Ping + RAM — the standard stuff, also there
Every stat has an individual toggle. Don't want server metrics in singleplayer? Turn them off. Just want a clean FPS counter? Also fine. You also get size and opacity controls so it fits any setup.

Curious what stats you all actually care about seeing while playing what would make this more useful for your setup?
