About this mod
Adds new occlusion planes for culling in many exteriors. Can help FPS. Merged and modular options to be compatibility friendly.

PFTP adds occlusion planes to cull unnecessary rendering. Like ExRB but for exteriors.
- Simply adds occlusion planes to various exteriors. Typically inside buildings and terrain.
- No wild edits or otherwise forcefully subjecting you to my "creative vision."
- Cleaned in xEdit and also checked by hand. Zero UDRs or ITMs.
On paper could help many PCs, but especially weaker GPUs. My aging Dell (1050 Ti, 2012 i5) gains up to +10 FPS looking at the motel in Novac.
Details?
Spoiler:
Occlusion planes are 2D flat rectangular planes used for occlusion culling. In FNV they stop certain things (mostly landscape textures & NPCs) from being rendered, relative to camera perspective. They're handy to reduce draw calls for your GPU, and are typically hidden inside solid structures so things you can't see don't need to be rendered. While Gamebryo engine games use room bounds to cover occlusion for interiors, planes are typically supposed to be used for larger exterior areas to lessen GPU strain. Vanilla New Vegas lacks planes in a lot of areas, likely due to limited time, so GPU bound performance suffers.
For the weaker GPUs that struggle with rendering a line in MS Paint, PFTP might help.
Here are the areas with newly added occlusion planes as of typing:
* There are 2 merged ESM options, with and without Vegas + Freeside, as well as the option to use individualized modules. Pick your preference.
Most mid-range to lower end systems that are low on graphical horse power can expect a few extra FPS in these exteriors. Novac had a ~10% FPS gain on my LG Smart Fridge. Another tester gained only ~2% more FPS on a high end gaming rig. Heavily depends on specs, number of in the area NPCs, and your mod list. As a rule of thumb, expect GPU-bottlenecked systems to get the best gains, but you can test either way to see if it's a mod that helps you.

Compatibility?
Spoiler:
TL;DR: Compatible with almost anything that doesn't remove or otherwise drastically reposition things I put the planes in.
Tested as fully compatible:
Known incompatibilities:
As you can see, mods that only tweak/add to areas are often fine. i.e. Willow unbarricades the far left bungalow as a player home, and it works fine.
I also avoided placing any planes in decor in case another mod moves them. So anything not moving terrain or buildings usually works out of the box.
Individual modules are provided in case you run into compatibility issues with any areas. You can optionally make your own custom merge with this.
You can additionally mix this with DXVK, NVHR, and NVTF to really watch some FPS magic.

Tested as fully compatible:
- YUP changes are forwarded
- ExRB - Extended Roombounds
- Fog Based Object Culling
- Aqua Performa - Strip Performance Fix
- Performance Of The Gods
- TTW (although FO3 areas aren't covered)
- Classic Adobe Buildings in Mojave
- Classic Adobe Sloan
- Simple Open Freeside + Strip if using my No Strip or Freeside version
- Wasteland Flora and Terrain Overhaul
- Enhanced Landscapes
- New Vegas Landscape Overhaul Re-Remastered
- Enhanced Mojave Landscapes (WIP)
- LSO - A Lightweight Strip Overhaul
- Afterschool Special
- A World of (Less) Pain
- Willow - A Better Companion Experience
Known incompatibilities:
- No Sleep Till Goodsprings has it's own module, so use it instead of my merges.
- FNV Occlusion Overhaul is unsupported by it's author and buggy. Pair PFTP with ExRB instead.

Downsides?
Spoiler:
Very little outside of the compatibility section. It's a fairly light weight mod, and every plane is entirely inside things that you can't see through anyway.
In theory you could lose a few FPS processing the extra occlusion in certain CPU-bound rendering situations, but given the tester still had 100+ FPS, we're talking 1% performance loss. It's pretty negligible, and any GPU bottle-necked (or bottle-neckless) scenarios can potentially still get performance gains.

Load order?
Spoiler:
Okay so you know YUP's deal? And how YUP has to be placed above any other ESMs? Place PFTP right under it.
