Nvidia Card - No Ground? Read here.

There are quite a few people having issues with graphics cards "Nvidia" and are petitioning GM's. I posted this in the WoW Technical, but I know alot of people come here to read for bugs, etc and exclude looking at the Technical support forum. I have found a work around to help alleviate a bit of CS issues on this problem.

Currently as of the current patch, alot of players are experiancing some problems with graphics. This problem has to do with something pushed in the new patch. Unknown at this time, however no one can figure it out.

What Happens?

Problem: The ground/terrain .WMO files are not rendered with the current graphic settings. Ground is walkable since the terrain files are loaded. Textures will not show after going to ghost form, and the filter for the world blue screen is causing textures to dissapear.

Whats causing it?

A Nvidia driver problem is causing a Buffer overflow somewhere. Though unknown how or why, the actual items are being loaded multiple times and causing your graphics card to over render making rips/tears and loading to many particles, artifacts and instances of one given graphic.

How to fix?

Currently on the driver side, Nvidia is not going to change there software. As it is an unknown issue, they are not going to adapt to fix a minor bug only affecting a certain portion of the cards.

The current walk around is this:

Open your tab for Video Settings. ("Press ESC, or hit your little computer on your quick bar").
Click to enter "Video Settings".
Disable and turn down all your graphics on your graphics card.
Save - Exit the Video options.

Turn off WoW.
Right click to edit your WoW.EXE (Right click your WoW.exe file and go to Properties)
You will see Location that reads:
"C:\Program Files\World of Warcraft\WoW.exe"

Change this to render in OPEN GL by doing the following.
"C:\Program Files\World of WarCraft\WoW.exe -opengl"

Note this is going to change WoW to run in OPEN GL not DirectX.

When you enter into WoW the graphics will be reset, once again Log in, go to your options menu and turn the graphics back to where you want them.

Save, exit wow again.

Revert the changes back to DirectX by going to the WoW.exe and removing the -opengl.

EXAMPLE it should be changed back to:
"C:\Program Files\World of Warcraft\WoW.exe"

Restart WoW and it will reenable the DirectX driver.

----------------
This method has been tested, and been confirmed as a working work around for the current bug. What is happening is textures are overloading the directx signal being sent to card. Unsure what is causing it, or how to trace it back to the function.

ONCE AGAIN: This is not a problem with WoW, or with your Nvidia drivers. Some bug in DirectX relay from the WoW to Nvidia using DirectX is causing it. Unsure when it will be fixed, but it should be soon. Hopefully.

If it does it again, repeat the process to clear the DirectX overload.
