Also there is a workaround of sorts. If you kill the sim in task manager when its stuck at 6% then restart the sim, hit continue at the pop up the sim will load in the usual amount of time pre-patch.
I’ve also been getting blurry runway textures on landing with airports I have stored on my SSD drive and last night got the infamous FPS/VRAM bug on landing.
Patch has been a complete disaster for me.
