• XP32 Maximum Skeleton Special Extended – XPMSSE
• Crash Logger SSE AE VR - PDB support Absolutely install the pdb related to your Skyrim version too.

• Address Library for SKSE is needed for SSE/AE
• VR Address Library for SKSEVR is needed for VR

Physics outfits are essential elements that add life to Skyrim. However, one inconvenience is that physics can break after dynamic movement. So this mod was born to solve it immersively.
Thanks to skypia :)

To be able to change the physics configuration at runtime, through papyrus
Thanks to SesamePaste :)

To solve the infamous colossus bone bug
Thanks to Yanjding :)

Allows spells and effects to interact with HDT-SMP. Fireballs will not only send cheese wedges flying, but also mess up your hair. Immersion!
Thanks to jg1 :)

Another implementation of wind.
Thanks to jg1 and Kernel Panic:)

Before complaining about SMP performance, improve your setup with this guide by yours truly :)

It does not know more about modding than Reddit does, which is what LLMs use to give bad answers.

Look closer, especially if you have dark mode on - the version is chosen automatically, there's a dot to the left of your game version

Disable Fomod+ (MO2 menu: Tools - Settings - at the bottom of the Plugins tab), restart MO2, install FSMP

Unlikely, see sticky post in the forum here

You're missing a required mod, check that you have:

• ConsoleutilSSE NG
• PapyrusUtil
• JContainers SE installed, then reinstall FSMP.
  Note: if you have:
• Campfire - Complete Camping System
• and/or Simply Knock SE
• and/or Wearable Lanterns all of those need to be loaded before (Vortex) or above (MO2) PapyrusUtil SE.

Short answer: in the FSMP MCM, Simplification tab, uncheck "Auto adjust max number of SMP NPCs".

Long answer: read the full section on Max Skeletons Number

FSMP is a complete replacement and enhancement of that mod. HDT-SMP only works on game version 1.5.97 and is a lot slower than FSMP. Do not install it together with FSMP.

Please join our discord, we'll try to get you there.

You're reading this in the wiki.

You can submit them on github.

Advanced_Vector_Extensions are extensions to the instruction sets for microprocessors from AMD and Intel. All Intel CPUs starting with Sandy Bridge in 2011 and AMD processors on their "Bulldozer" architecture and beyond offer this set of instructions. Three versions exist: AVX, AVX2 and AVX512.

https://www.quora.com/How-can-I-determine-if-my-CPU-supports-AVX-instructions

CUDA is a NVidia API enabling general purpose processing on the GPU. Useful when the GPU is powerful, the calculus are adapted for GPU, and the transfers between the CPU and GPU minimal.

AMD GPU don't support CUDA, see here which NVidia GPU support CUDA.

Usually not.

CUDA support is enabled by default, but will only work on the CUDA versions. CUDA versions with CUDA disabled in the configs.xml is absolutely not supported.

CUDA version do not check the capabilities of your GPU, so it may crash if your card is too old. Do not ask how old, just test, it will be way quicker.

The absolute minimum required compute capability is CUDA 3.5, to support dynamic parallelism.

The following parts of the collision algortihm are currently GPU accelerated:

• Vertex position calculations for skinned mesh bodies
• Collider bounding box calculations for per-vertex and per-triangle shapes
• Aggregate bounding box calculation for internal nodes of collider trees
• Building collider lists for the final collision check
• Sphere-sphere and sphere-triangle collision checks
• Merging collision results (note that this may reduce performance for objects with lots of bones, as the merge buffer can get quite big - still working on this!)

The following parts are still CPU-based:

• Converting collision results to manifolds for the Bullet library to work with
• And, of course, the solver itself, which is part of the Bullet library, not the HDT-SMP plugin

This is still experimental, and may not give good performance. The old CPU collision algorithm was heavily optimized, so matching its framerate is not easy. You will need a high end GPU and a low end CPU to see any real performance benefits.

Yes, your CPU must support the SSE 4.1 cpu instruction set.

Bullet is a physics library enabling to do physics collision calculus, among other physics calculus. You don't need to install the Bullet library.

This is a replacer for HDT-SMP. This totally replaces the previous version of HDT-SMP. You don't need HDT-SMP.

Those below are suggestions, be smart about them, and report your own tips :)

• configure this mod with the FSMP MCM,
• Free FPS (shameless promotion, since I'm the author too).
• write your own hdt smp xml files: here is treota's Guide to HDT-SMP Users/Modders, and here is the FSMP-Validator hdtSMP64.xsd file in which you can find exactly all I know about the smp xml.

The configs.xml file configure the functions provided by the physics engine (of the dll provided by this mod, exactly), the other xml files declare which bones, which collisions, the precise values of bouncing, collisions, etc.

I used both, and endorsed gratefully CBPC. CBPC description page is enlightening.

It's included from 1.49.0 version, and jg1 provided another implementation in SMP Wind.

Easy Wind and this mod won't be mergeable as long as nexusid1234's source code for wind isn't available, or he merges them himself, or somebody reimplements it from the articles he wrote. Easy wind and this mod are totally incompatible, the last one loaded wins.

Report the bugs. You may even solve them :)

You can. See the part on compilation.

• Install the requirements.
• Take the latest version on the Nexus. The previous versions aren’t supported.
• Install it through a mod manager. The manual install isn’t supported.
• For a first install, choose AVX, No-CUDA, Release, Extreme performance configuration.
• If you have a problem, reinstall with the No-AVX version. Solve your problem.
• Optional: once you have a stable setup with FSMP working great, improve your performance by testing:
  • If, for you, upgrading AVX gives you more fps; it depends on your own very specific setup, so don’t ask, and test by yourself;
  • If, for you, upgrading to CUDA gives you more fps; it depends on your own very specific setup, so don’t ask, and test by yourself.
  • Once you have a setup working great, improve your quality & performance by testing it with the FSMP MCM. Make sure it
    • improves visibly the simulation quality (it depends on your own very specific setup, so don’t ask, and test by yourself; it’s no use to improve the quality configuration if you can’t perceive it);
    • doesn’t lower the performance under what you’re willing to accept. Test in a small room (no NPC, high fps) and in a crowded city (it depends on your own very specific setup, so don’t ask, and test by yourself; it’s no use to improve the quality configuration if you don’t like the fps loss).
