Games config INI does have a "Terrain" setting inside, but any change to that just makes game reset it to 0 - was able to find a way to patch game to allow the setting to be increased, but that didn't seem to make any difference in the game.

Luckily I saw we have a TAA patch available on the main page, many thanks to the person who made it, seems the function that patches is what handles setting up the games graphics values based on the INI settings.

That function does seem to have a section that would set up the Terrain scaling value, but right now always sets it as 1.0, ignoring any INI setting, so that would explain why INI increase made no difference - fortunately that also means it should be simple to patch šŸ˜ŗ

As a test I also tried 4.0, that did seem to boost the distance a lot, but then sadly made the far distant terrain become all glitched out/corrupted, with parts turning purple too, not really playable...

After that I tried out 2.0 again, and unfortunately was able to see that the far terrain was sometimes still being glitched too, not as badly as 4.0 made it (no purple corruption at least), but it was definitely the same kind of glitching - fortunately the way it was glitching there isn't too noticeable, so I've kept it as 2.0 in my game, and only really been able to see that corruption at a single spot so far.

It's nowhere as bad as the glitches 4.0 had (eg. no purple corruption), but it was definitely same kind of glitching (stripes appearing on far terrain), fortunately that kind of glitching isn't too noticeable so I've kept it as 2.0 in my game, and only really been able to see that corruption at a single spot so far.

My guess for why the corruption happens is maybe game doesn't increase memory allocation for the terrain in line with that scaling value - with all the values I tested here the game always seemed to be using ~10.5GB of VRAM (on a 24GB card), nothing seemed to be increasing it...

Maybe if the code that allocated the terrain buffer was located the amount allocated for it could be increased, I don't really do much GPU programming though so not really sure how buffers like that get allocated.

The increased LOD distance helps a lot to keep mid-range terrain from melting/popping in front of your eyes, much less distracting... IMO that's worth the small chance of distant terrain having minor glitches.
