same here, I have had this issue for over a year now and it renders big box unusable. In addition to the long freezes (sometimes it neer recovers) I have to wait nearly 5-10 min for bigbox to load. I've started from scratch too and reimported some roms to see if my library was causing an issue and its not. Best guess it icue (ive heard conflicts with this) are happening but i have never been able to remedy by closing services and software, it always happens even on fresh windows installs. This is why I think its that fucking piece of crap corsair keyboard which i actually love but hate icue software. Anyone have any ideas?
