How to Show Live Delta in Iracing

Shows how to show live delta in iRacing and enable on-screen delta timing. Quick guide for iRacing drivers to fix the display fast now and improve lap times.

If you want to see your live delta in iRacing, the short answer is: enable the HUD/timing delta display and pick the correct comparison (Session Best or Personal Best). You’re in the right place — below are plain-language checks and exact steps to get the delta back on-screen fast.

Quick answer: how to show live delta in iracing

The live delta is part of iRacing’s HUD/timing overlays. Open the in-sim Options (the gear/ESC menu), go to the display/HUD or Timing settings, enable “delta” or “lap delta,” and choose the comparison reference (Session Best or Personal Best). If it still won’t show, reset the HUD layout or use a lightweight third‑party overlay.

What’s really going on

“Delta” is the on-screen time difference between your current sector/lap and a reference lap (your best lap, session best, or another driver). iRacing draws that in the HUD/timing area. If you can’t see it, either the HUD/timing element is turned off, you’re in a HUD mode that hides extras, or a custom overlay/graphics setting is blocking it. The data is there; it’s just not being shown.

Step-by-step fix

  1. While in a session press ESC and open Options (or click the gear icon). Look for Display, HUD, or Timing settings.
  2. In that menu enable “Show Delta,” “Lap Delta,” or enable the Timing HUD element (labels vary slightly between versions). Turn on timing overlays if they’re off.
  3. Pick the reference: set the delta to compare to Session Best or Personal Best depending which you want to follow.
  4. If you still don’t see it: reset the HUD/layout to Default in the same menu — that restores missing elements.
  5. Confirm you haven’t hidden HUD globally (some drivers hide HUD for screenshots). Re-enable the HUD or reset the view.
  6. As a fast fallback, use a small external overlay app (SimHub, Crew Chief or the iRacing Telemetry-based tools) to display a live delta if the built-in HUD is failing.

Extra tips / checklist

  • Delta only updates when the timing HUD element is visible — check both “Timing” and “Driver Info” toggles.
  • Make sure you’re in a session (practice/qualify/race). Some HUD elements hide during certain replays or camera views.
  • If you use custom camera packs or UI mods, test with a default setup — mods can hide HUD parts.
  • Set delta reference to “Session Best” for pace against the current session, or “Personal Best” to chase your own fastest lap.
  • If your framerate/UI stutters, HUD elements can act flaky — try restarting iRacing after changing settings.

FAQs

Q: Why does the delta show +0.000 or blank?
A: That means no valid comparison yet. Complete a reference lap (Session or Personal Best) so the HUD has something to compare.

Q: Delta appears but compares to the wrong lap. How do I change it?
A: Go to the HUD/Timing settings and switch the comparison option between Session Best, Personal Best, or another driver.

Q: I pressed the HUD toggle and lost all on-screen info. How do I restore it?
A: Reopen Options → Display/HUD and choose “Reset to Default” or re-enable the Timing/Driver info overlays.

Q: Can I get a more detailed live delta (sector-by-sector)?
A: Yes — enable sector delta in the same Timing/HUD menu or use a telemetry/overlay app for customizable displays.

Short wrap-up

The live delta is just a HUD/timing toggle away. Check Options → Display/HUD → enable “delta” and pick Session or Personal Best. If that fails, reset the HUD or use a small third-party overlay to get immediate feedback. Try one change at a time and test with a quick out-lap.
