Helping the SMP mods community

.

SMP mods exist for a long time, and I am grateful that there are so many.

Still, SMP configuration is not easy. I have in the past provided a documentation for this.

In FSMP 3. 2. 0, I introduce the 'smp report ' console command.

'smp report' writes a full report with errors and warnings concerning the .xml and .nif files of your modlist SMP mods.

Adding 'warnings' prints no only the errors, but the warnings too.

Adding 'gear' limits this to equipped items.

I hope this will help the mods authors, modlists maintainers and players alike, cheers!

FSMP - Faster HDT-SMP is a high-performance physics engine replacement for Skyrim that dramatically improves the speed and stability of cloth, hair, and cape physics. With over 67,000 endorsements and 10 million downloads, it's the go-to mod for players who want smoother, more responsive physics without the lag of the original HDT-SMP. This mod is essential for anyone using physics-enabled armor or hair mods.

✨ Key Features

Replaces the original HDT-SMP physics engine with a faster, more optimized version.
Improves performance for capes, clothes, hair, and other physics-enabled objects.
Widely adopted with over 67,000 endorsements and 10 million downloads.
Actively maintained with a recent update in July 2026.

📊 Pros & Cons

✅ Pros

  • Massive community trust — 67k endorsements and 10M downloads means this is battle-tested.
  • Noticeably smoother physics for hair and cloth — no more jittery capes or hair clipping through your body.
  • Actively updated (July 2026) so it stays compatible with the latest Skyrim versions.

⚠️ Cons

  • Requires the original HDT-SMP framework — you can't just drop this in and expect it to work without the base mod.
  • Performance gains depend on your hardware — on lower-end rigs, you might still see stutter with heavy physics loads.
  • No detailed install guide in the description — you'll need to know your mod manager or manual install basics.
🎯 Is This For You?
For Skyrim players who use physics-enabled mods like HDT-SMP hair, capes, or armor and want better performance. If you're tired of laggy cloth physics or crashes, this is a must-have. Skip if you don't use any physics mods — it won't do anything for you.
📦 Install:Medium· 5-10 minutes

💡 Beginner Tips

  • Make sure you have the original HDT-SMP installed first — FSMP is a replacement, not a standalone.
  • Use a mod manager like MO2 or Vortex to avoid overwriting files manually — it'll save you headaches.
  • If you're on Skyrim SE/AE, check that your game version matches the mod's requirements — the recent update likely supports the latest patch.
