Performance Optimization


What?

Basically, stuff that are occluded by the fog and are *not* visible, are culled, saving memory and improving performance.


For obvious reasons, performance gains depend on your hardware, but generally, all hardware configurations should benefit from this mod.

Guaranteed performance improvement for Dead Money and Point Lookout, since those areas have thick fog, and the mod was made with them in mind.

(Ironically enough, Point Lookout's gains are not as impressive because the main bottleneck is caused by... water. Fix for that will be soon™️ in another mod.)


Mod adjusts following settings:

  1. Object distance
  2. Actor distance
  3. Item distance
  4. Grass distance
  5. Decal distance

I haven't found other render distance settings impactful on performance in any meaningful way.

So far, the biggest offenders are obviously objects, decals, and lights.


You won't be able to adjust draw distance settings in-game!

Mod uses your existing values as maximum range.



Compatibility:

Uh, everything? This an engine level override.


FAQ:

  1. I use *fog distance mod name here*, will this affect me?
  2. If your fog is shorter than 15000, yes. If it's above that, no.



Credits:

JIP LN for having uh, easy to copy classes.

Instructions

Dynamically adjusts draw distance in accordance with the fog to improve performance with little to no visual difference.
