nvwgf2umx.dll issue

Post by sly433 »

Good afternoon,

P3D V5 worked fine for me for a while, I took a bit of a break, left it installed as is.

I got a new NVMe and tried to install P3D on there and was getting a "nvwgf2umx.dll" error, tried on the drive it was on before (also a NVMe) and same issue. Any idea what may be causing this please?

Un-overclock the graphics card.

Run it at nVidia's 2080 reference clock rate.

Cheers mate but, no idea how to do that? I'm not running any sort of overclock and P3D used to run on this exact same hardware before?

The thing is that nVidia sells by far the most of their graphics cards through OEMs, like Gigabyte, Asus and many others, in your case Aorus.

Many of these OEMs overclock the cards as a matter of routine before they ship them to the retail channel, and if you search for your card on the web, it is overclocked. You didn't do it, the OEM (Aorus) did. If you also search the web for the error you got - just search for this string:

nvwgf2umx.dll

you'll see that this is a typical error resulting from overclocking.

The first thing I would do here is to contact Aorus support and ask them how you can get rid of the overclocking.
