I have been having the same issues ever since 3.0 launched, and it's not just Idyllshire (though this zone is the most problematic). Foundation, Tailfeather and Cloudtop will also cause the dx11 client to freeze up (and occasionally entering the Void Ark raid). Process Explorer shows the game hovering at 12.5% CPU usage, but it's not actually doing anything, and I have to manually kill the process and restart the game (which has me rolling the dice, because it can still freeze back up until the teleport is finished and the zone loads fully). This has happened under both Win 7 Professional, and Win 10. Drivers all up to date, specs: FX 8150 CPU, GTX 970 GPU, 16 GB RAM. Dx9 client has no issues (other than not looking quite as nice).
