SignalRGB causing system-wide stutter/mouse lag on fresh Windows 11 (no other RGB app installed)
Hi everyone,
I’m hoping someone here has dealt with this specific conflict. I’ve just built a new PC and I'm experiencing severe system-wide stuttering and mouse lag that is directly tied to SignalRGB.
The Issue: After SignalRGB has been running for a while, my entire system becomes unresponsive, specifically with mouse input lag. The moment I "End Task" on SignalRGB.exe in Task Manager, the system returns to normal instantly.
My Setup:
- Motherboard: Gigabyte B760M AORUS ELITE
- RAM: 32GB Corsair Vengeance RGB
- GPU: Intel Arc B580
- OS: Fresh Windows 11 install (not activated yet)
Troubleshooting steps I’ve already taken:
- Completely uninstalled Gigabyte Control Center (GCC) and removed all associated background services/drivers.
- Switched the SignalRGB renderer from
QtWebEnginetoUltralight. - Disabled GPU lighting control (since the B580 isn't officially supported anyway).
- Confirmed no other RGB software (iCUE, etc.) is installed or running.
- Checked Task Manager for conflicts—only "Gigabyte Update Service" was visible and it has been disabled.
Has anyone else had a similar experience to this? Are there specific settings in SignalRGB (or BIOS settings like "SPD Write") that I should be double-checking to prevent this interrupt storm?
Only thing I notice is the prompt message of "Windows Is not Activated yet"
Any advice would be appreciated!
