does having lots of HDT physics effect fps?

[Xaqq]

i noticed if you have followers with hdt hair with collision for boobs and butt on weaker rigs it will affect fps performance, but i'm not sure if that's exactly what is affecting performance. For example in towns if you have lots of female npcs with hdt physics outfits it may effect performance a bit...

 

but then again i'm not sure if that's exactly what is affecting performance, so my question is: for sure, does HDT physics definitively affect fps at all?

You really need to start researching stuff before clicking the dl button, your pc will thank you for it.

As far as i know hardly any HDT mod mentions anything about an FPS drop. So like, you're not helping at all.

+ Exactly. Besides completely generalising the OP, you haven't contributed at all to the topic.

 

As for myself I've only dabbled with HDT in a few playthroughs, mainly for capes and I never experienced a noticable drop in FPS. I suspect that it impacts about the same as the Havok Physics with corpses, e.t.c. but that is just a guess.

Are all the HDT items from the same source?  Having multiple competing physics items can cause slowdowns or other problems. Two different HDT hair collections or the player's skeleton not matching a custom followers skeleton for instance.

Then you haven't bothered to pay attention, because frame drop is very much an issue, especially with collisions; and it's not the prerogative of the modder to state such when Hydro explicitly stated this when she produced the framework to begin with; with SMP even more so; she even stated it in english so there was no confusion.

 

Every topical content thread and mod thread has also stated as such, Nhuru's thread, Brukes' thread, Bazinga's thread, and every thread dealing with SMP have also stated such; PRZ, ledo4ek and blabba going so far to detail which type of collision hits your framerate the hardest.

 

It's not incumbent for a mod maker to explain to you why a 4K textures uses more ram than a 2K one, and Hydro didn't make a commercial product bound by consumer law that she's getting royalties from either so her explaining the frame loss was a favor, not a right.

lmao the only reason i ask is cuz im playing on my old laptop right now.

 

my titan x pc still runs everything at 60 fps wiht very few stutters even though i smashed it with a ridiculously high number of mods the moment i downloaded skyrim an overrote it with my modded skyrim thru a flash drive > no regrets, no research needed >

 

but now that im playing on my weak rig away from my monster pc im trying to be a bit more careful.

i play on 2 different rigs with nearly the same exact mod setup except for ENB's cuz one is an old laptop the other is a monster desktop with a new titan X graphics card. what i noticed is that weaker rigs tend to be a lot more sensitive and it shows up in fps drops more often than stronger rigs that require you to literally smash it on the wall for you to see any fps effect. 

 

Here's my theory, on weaker rigs, if you're surrounded by npcs with full on hdt collision physics for boobs and butt and even maybe hair, that weaker rig will be severely affected, which can explain why fps drops severely in towns for me on my weak laptop rig evne though im using 512 compressed textures and no enb.

For what it's worth I also got rid of the framerate drops I once encountered after updating my rig to a i7 6700K. Same graphics card as before though, but we already knew that HDT PE taxes the CPU and not the graphics card.

I can't say if these framerate drops (hickups where the fps dropped to single digits for a few seconds) were HDT related though. If I completely turn off all HDT calculations now (by feeding HDT PE with empty xml files) I maybe gain 1 or 2 fps at best compared to a setup where I use my own body physics mod and some quite sophisticated HDT hair mod for the player character. That's while running around in Whiterun, dunno about Solitude.

 

I don't think drops on average fps when running HDT mods ever were a problem for me. As long as HDT PE worked as intended it always was about short hickups.

It often didn't work as intended though, there was that missing bone error which single-handedly dropped the framerate into single digits when it happened. But that didn't happen to me for a while now.

ye what i noticed is that if i equip certain hdt hair wigs with crazy ass physics frame rate drops severely and if i look away from follower using such hair framerate goes back up.

Can´t give any proof or mathematics about it, this is only caused on gaming myself, but I´m pretty sure, the frame rate impact from hdt is easy negligible.

 

I´m playing on a rather decent machine, but still stuffed up to the edge with mods, HD-Packs ( nearly everything "renthal" submitted ) and hdt weaponslings, hairs, boobs, butt and whatever.

Turning off the ENB let´s the game still run smooth like oil with about 50 fps. (which ist still good enaugh imho)

(I must confess; with ENB turned on; the average framerate is only about 35fps)
