Has anyone experienced severe stutter/freezing issues in iRacing once or twice a lap, any car, any track?

Setup:

  • Cube Controls F-Pro
  • Simucube
  • Heusinkveld pedals
  • SimHub
  • Trading Paints
  • Cube Controls software

Everything used to work perfectly.

Now, usually within 3–10 minutes of driving, especially while accelerating and upshifting, the sim suddenly freezes/stutters for a few seconds.

The important part is that this feels more like a system/input freeze rather than just a missed shift.

During the freeze:

  • Inputs stop responding
  • Upshifts don’t register
  • Pedals do work
  • FFB cuts completely for 2–3 seconds

If I keep trying to shift during the freeze, all the queued inputs suddenly happen at once when the sim recovers.

Tried Bluetooth and Wired.

Sometimes the shift audio still plays during the freeze even though the sim/input is locked up.

This has ruined races, qualifying, and practice sessions, many laps constantly to the point I cant do a proper lap.

I already tried registry edit fixes from videos like Dave Cam’s iRacing freeze/stutter fix, plus multiple USB troubleshooting steps, Bios update, but nothing has solved it.

I’ve also seen people mention Logitech devices causing HID sleep/wake conflicts. I currently have Logitech K400 + G502 Lightning connected, so I’m wondering if something is disconnecting/reconnecting briefly and causing the entire sim to stutter. GHub on and off.

Since this has happened on two separate PCs, I really feel like this is some kind of software, USB, HID, or iRacing-related conflict rather than pure hardware failure.

Has anyone seen or fixed something similar? How can i fix this?
