We really need someone in the forums to take this to the devs - would we have to open a ticket for that purpose?
They definitely tweaked something in the client this last patch which is causing these issues.
Someone on another thread advised (2nd link below) that it was a troublesome Windows 10 update, but I checked the KB number that he referenced and I didn’t even have that update installed.
I first described the issue in this thread:
I marked it as solved, only to find out the next day that the error returns every time I reboot, requiring me to reinstall the same gfx drivers over and over again.

In this thread I describe in a reply to OP, the compounded problem, which includes overheating - a problem I did NOT have before the client was updated on 3/10/2020.
If I reinstall the drivers, get WoW to run without the “3D Acceleration” error, then I play for ~10-30min, eventually my computer shuts off due to excessive temperature and I have to spend another 10min reinstalling graphics card drivers.
When I first posted about this issue, noting it was obviously caused by the 3/10 update, I was shocked not to find any similar complaints, but now I see I am not alone and this problem is probably under-reported.
My ability to raid with my guild was crippled by this client update, and it has seriously caused me to consider unsubscribing permanently because I cannot afford a new computer and probably won’t be able to for a long time.
I am going to attempt to uninstall Windows 10, revert to Windows 7, which was the OS this laptop was packaged with and also the only OS supported by the laptop vendor’s driver releases (as opposed to NVIDIA’s).
I’m going to try to keep documenting any potential working solutions on these forum, and I suggest everyone do the same.
