Im offiziellen Beth-Forum hat der User "austin" bereits den ersten, interessanten Hack veröffentlicht. Hier seine Anweisungen im Original:
In the folder unique to your character (It's somewhere in My Documents\ My Games for me), edit the Oblivion.ini file in the following ways:
Set uGridsToLoad = 10 (5 by default)
Change the fLandTexturingTilingMult = 0.5000 (2 or 2.5 by default)
(Note: This does increase load times.)
The first tweak loads more true grids, and the second tweak reduces the tiling that occurs on those grids.
I also have noticed that this does mess up water reflections a bit. I have been able to fix the problem slightly but am still researching how to amend it completely.
To somewhat fix the water, change this:
uNumDepthGrids = 1 (it's 3 by default).
There are LOTS of things you can change in there with respect to resolutions and things.
By default, the water only reflects the land. Inside the ini you can change it so it reflects all trees, static objects, actors, and other miscelaneous objects:
bUseWaterReflectionsMisc=1
bUseWaterReflectionsStatics=1
bUseWaterReflectionsTrees=1
bUseWaterReflectionsActors=1
You can also mess with the tree settings, changing the maximum distance real animated trees can be placed (the variable is fLODMultTrees).
Also ich werde den Hack mit sicherheit ausprobieren, vorher natürlich die Original-ini-Datei sichern. Bin schon mächtig gespannt, was das bringt. Evtl. kann man damit High-End-PC´s doch noch grafisch gegenüber der XBOX-Version tunen.
