Hi!

Click HERE (you may have to do a "right-click" then "Save Target as..." select file type "All files" and make sure to save with file name "Wiz-8-OpenGL-Fix.rar") to download the fixed OpenGL driver for Wizardry 8.

In the RAR archive is a version of Wizardry 8's OpenGL driver file, srDD_OpenGL.dll, that has been patched to fix a texture clamping bug.

If you get black grid lines on the inventory and loading screens and in the HUD of the main game screen when playing Wiz 8 in OpenGL mode then you need this fix.

Extract the fixed srDD_OpenGL.dll file into Wiz 8's /Dll subfolder (ie. C:\Program Files\Sir-Tech\Wizardry 8\Dll) overwriting the old file.  But, first you'll have to uncheck the Read-only attribute on the old file before Windows will let you overwrite it.  To do this, locate the old file in Windows Explorer and right-click on it and choose Properties in the context menu and uncheck the Read-only attribute in the file properties window.  Don't forget to make a backup of the old file, just in case!

Now your game will display properly.  Have fun!

Alternatively, you could fix your srDD_OpenGL.dll file yourself if you are familiar with hex editing since all that needs changing are two bytes!

Locate the byte at offset 0x321B in the file and change it from 0x00 to 0x2F.  Then, change the next byte at offset 0x321C from 0x29 to 0x81.  That's it!  Don't forget to save your work overwriting the old file.

The two bytes you alter changes an OpenGL token from GL_CLAMP (0x2900) to GL_CLAMP_TO_EDGE (0x812F).  This is an attribute which is associated with all of the game's textures which helps to tell the OpenGL subsytem how to map the textures onto the game's geometry correctly.

If you have any have any questions or need help post your questions in this thread at VN Boards' Official Wizardry 8 Forum.
