No joy

I’m getting the exact same. Tried everything, restarts, cache, safe mode, empty community folder etc…
Randomly happens on a control input (any) axis or buttons - none specific.

Glad I am not the only one. I’ll sit tight for now before doing anything drastic.

To fix it :

  • Disable Nahimic Service and uninstall Realtek audio drivers.
  • Update your drivers (I recommend Avast Driver Updater, it’ll check ALL your drivers).

I tried to do this and so far CTDs have gone (tested on a 20 minutes flight and I’m going to test on a 1-2hours flight tomorrow).

does the sound-driver update ( and/or disable nahimic ) helps in your case too ?

As many others are now posting in the forum, disabling Sonic Studio Mixer fixed it for me. I have done
5 hours today totally CTD free.

Windows Settings > Apps > uninstall Sonic Studio III. Then restart Windows. You may have to remove the entire ASUS Sonic Suite

I don’t know if Sonic Studio is only relevant to Asus MB’s but worth a look if you have it.

I’ve got the same issue with WwiseLibPCx64P.dll , but your Fix doesn’t work because I have both of the drivers not installed. Somebody has an idea?

11

if you get this error allways an easy check whether your sound-drivers are involved is to disable the windows audio service. Yes, you have no sound , but in case you no longer get the error, you know where you have to search the problem ( sound drivers ). Main cause was often the Nahimic service.

THANK YOU SO MUCH…
I was going crazy… uninstalled the drivers and got rid by the way of additional sonic output devices that were already driving me nuts.

If non of these fixes work, uninstall Razer Cortex
