Check your audio output devices in Windows - Settings - Sound and in the sim itself. They get messed up by some combination of the driver installs and even some of the Windows updates. Usually the cause of null pointer memory access error.
You want to make sure they are set to an actual output device and not one of the motherboard mixers.
It will be such a shame if they release this build without the VRAM optimisation because the game ready driver isn’t available which stops the trees in the sky with the optimisation.
Is it possible to install the studio driver from within the Nvidia game force app as I can’t seem to find it as it says I have latest installed but that’s the last game ready driver? Please if anyone could help would be great, thanks!
Don’t mess about with drivers now. See if Asobo have included the VRAM optimisation before spending time doing that.
If they haven’t, and they might not because of the lack of game ready driver, you don’t need the driver anyway as the fix it contains is for if VRAM optimisation is included in the sim, this optimisation was removed after the first beta build.
Please lets all relax. Personally I have no intention of going anywhere near MSFS for a few days. Not until I have an NVIDIA update and I read in the forum that all things are well.
No rush. Early worm catches a cold I always say !
