1.0.4 introduced mipmapbias, which directly correlates with LOD distance. Nvidia has quite
the compilation on tweaks and mipmapbias is among them. You can find the setting in your rendering.ini file.
It doesnt relate to the problem what i have with the grass draw distance and pop-ins, based on the comparison.
There are certain parts of foliage/grass that is only drawn when Geralt is like a few meters away, it basically "grows out" in my sight and its irritates my eyes honestly.
I say part, because big part of the foliage is already rendered and has a very big draw distance which is good, but with 1.04 somehow this changed into this 2-way version. Which only renders close and far rendering. Which is just bad, it looks bad.
Pop-ins also up to them to fix, i even saw floating NPC names with no actual character under them until i was like 5 meters close.
Or when i fast traveled to Novigrad and like 20 NPCs spawned in the same spot when i looked there and started walking.
Again, i didnt not have this before 1.04.
Everything was perfectly fine pre-1.04.
And AFAIK i cant even go back to 1.03 since savegames then wouldnt be compatible.
