Registry HACK for LOD
Borrowed from S A V @ XS (as in dont ask me anymore coz I simply dont know):
Start regedit.exe and find/make "D3D_88481200" key.
For all nvidia-cards: LOD 0 (00,00,00,00) ... LOD +15 (78,00,00,00)
And for all ati-cards "LODAdj" key (0..10).
"D3D_88481200" key not present in registry by default. It must be created manually in the same place where stored all other video driver options.
Try search for ".exe

3DOGL_" string and create "D3D_88481200" key (type - REG_BINARY) in the same place. Key value interval is: from "00 00 00 00" (LOD 0) to "78 00 00 00" (LOD +15).
Note: if you find too many pathes to driver settings: uninstall driver, use some driver-cleaner (or registry-cleaner) tool, re-install driver, re-do search.
Or use RIVATUNER!!!!
Well first of all thanks to Victor Wang for the screenshots.
this is really simple:
Get the latest version of Rivatuner ( 15.8 )
Then go to Poweruser tab
Then sroll down to "Force VGA Device ID" and enter 92:
Hopefully this will help some of you.
