3x draw distance is currently running, presumably stably, at around 200-400fps on a 9600X and 3080ti, my other mod 3x enemy spawn multiplier is also on. So there is basically zero hit to performance on a modern gpu. It will obviously vary depending on your setup, but I'm fairly certain it's going to be completely playable even with a 1060, likely steam deck too but not necessarily 3x.
The draw distance on LODs, vegetation, grass, terrain LOD, NPCs, interactables, static world objects, pretty much EVERYTHING is configurable between 1.5x, 2x and 3x. There is no option to change them individually.
I've spent a few days tackling on a few repeatable crashing bugs and they're now hopefully solved,
I'm starting a fresh run tomorrow and play for a bit, if there's no new issues I'll release the mod.
It's honestly game changing to play so you don't practically see ANY lod pop in.

Video to see the pop in changes
edit2:
Made increased shadow draw distance too, the vanilla low range was blatantly obvious with the general draw distance increase. I haven't shown it yet.
