EAC update causes freeze/stutter on every mouse movement -- fully reproduced and isolated
EAC update causes freeze/stutter on every mouse movement — fully reproduced and isolated
Since the EAC update, I get severe lag and freezes in Rocket League every time I move my mouse - both in-game and in the menu. When the mouse is completely still, the game runs perfectly fine.
What I tested:
- Two completely different mice (Attackshark X1 and Logitech G400) - identical issue on both
- Both mice using generic Windows HID drivers, no manufacturer software running in background
- Mouse settings saved onboard, no background software at all
- Tested polling rates 125 Hz, 500 Hz, 1000 Hz -- no difference
- Connected directly to laptop and via USB hub -- no difference
- Xbox Game Bar fully uninstalled -- no difference
- Checked Windows Event Viewer -- no EAC or RL specific errors
- Verified game files, reinstalled RL, EAC, Epic Launcher -- no difference
- Launched without EAC --> problem completely gone
Conclusion: This is not a mouse issue, not a driver issue, not a hardware issue. EAC is interfering with mouse input handling on certain system configurations. The issue is 100% reproducible and fully isolated to EAC.
Anyone else experiencing this? Would be good to know if more people are affected so Psyonix escalates it faster.
Already submitted a support ticket -- so far only got the generic troubleshooting script response to reinstall everything.
