Do you see/measure a difference in stability and performance, on versions 1.11+, between a CUDA version with CIDA disabled and a not-CUDA version? (30 comments)
Tested CUDA vs AVX2, inside Silver-Blood inn. CUDA gave me 59 FPS while AVX2 gave me 65-70 FPS, so measurably worse performance using CUDA over disabled CUDA+AVX2. R5 3400G/16GB ram 2070 super
So my GPU has a lot fewer cuda cores compared to the other user who reported improvement with CUDA on. 2070 super isn't exactly an entry level card so probably only flagship level cards would get some improvement? Would be interesting to know how a 1080ti performs with it.
Enabling CUDA cost me like 10fps but it seems that it has also removed the lag/slowdowns every 10 seconds when wearing some high poly stuff so I can actually play wearing fancy stuff now.
on my 12900k+RTX4090 AVX2+CUDA have a lot of stutter and i lose 10-15 FPS if there is a lot of NPCs with SMP clothes, only AVX2 seems waaay more stable for my config.
All versions stop responding, with no errors, to body smp with KS Physics installed after a point. AVX, AVX2, Cuda, No Cuda, whatever. Rebooting fixes it temporarily. (Linux/Wine/Nvidia 515.) Some lead to "cuda driver version" related errors.
Performance itself is excellent and into the "Not relevant impact" range.
I think its something primarily Linux/NoVidia side.
Whiterun, on the stairs of dragonreach looking towards the bannered mare, 3rd person view, Dint999's hair 18d
AVX: 18-22fps AVX2: 18-23fps AVX512: 19-23fps These will fully show CPU usage to 48%, GPU 50-70% in taskman (8 cores in use, Non-Hype(r)Threading, thus it really means full CPU usage)
CUDA+AVX512: 28-33fps CPU usage: 30%, GPU 55%
Weird... I expected more GPU usage from this... but, it's... not much different, except my CPU isn't being cooked anymore.
I spend nearly a week of debugging my Skyrim SE installation because of freezes on cell changes or after loading a save. This was a really nasty bug. I could fast travel 45 Minutes without a single issue than i wasn't able to load the save at all 10 times in a row. While debugging i have tested many different versions of Faster HDT-SMP none gave me a freeze or a CTD. I think most of us forgot how HDT was on Skyrim LE or never used it because beeing to young 1.25 made me laugh after doing a smp reset, uhm can we have smp water?
I found the little sucker causing the bugs in my installation and even managed to uprade my installation to the actual AE build while doing. Best running build for me is 1.24 avx with cuda. I disabled the check of the view angle and changed the distance to 1024. Some might say i got a bit crazy. My installation has an actual size of 94 Gigabytes. There aren't any new land mods or city overhauls and only six follower mods. I'm using 8K textures and high poly mods when ever i can find them, my pine branches are 16K. While using a resolution of 5120x2880 i never have more than 50 FPS interieur with the RTX 3080 Ti! I'm using the CBPC Only variant of the 3BA body and HDT-SMP only for skirts or belts. My GPU is allways at 100% usage and cpu (9700K) usage is at 20%. But when i try to use the CPU for HDT-SMP i get between 10 and 20 FPS in Breezehome with five girls wearing SMP skirts. CPU usage hardly rises. When switching to the cuda version on the allready tortured GPU i get between 30-40 FPS! And that setup feels even smoother on very low FPS exterieur.
SMP water with water bones ! 5120x2880 / 1920*1080 = 7 times the number of pixels of 1080p, wow!...
1.29 solves the bugs introduced in 1.25, and I think you'll have a way better performance than 1.24
A question if I may: do you use CAO to uniformize your textures definition, and if yes how do you choose what to do? Personally, I use twice the advised resolution for textures, because I use a zoom mod.
1.24 is still way better for me. I get allmost twice the FPS that i get with the 1.29 version. Sadly my mainboard has coil whine. When using 1.29 it sounds much more chopy I would say it's some sort of latency related.
No i don't use COA but maybe i should, thanks for the tip! Currently i'm swapping many mods, i had a real old setup with many mods i allready knew from Skyrim LE. Thinks like the bijin wifes and many old but bad ported follower mods. Don't get me wrong the bijin series are still great mods and outstandig for the time beeing made, but they aren't high poly headed. I wish someone would make them with high poly head. What i wanted to say at this moment i'm nowhere near of optimizing textures
Locks like my machine is some sort of mystery I did further testing but the results didn't change. I tested in breezehome and windstad manor. As i said i use HDT-SMP only for armor and clothes. I used a save with five girls wearing SMP skirts but nothing else that uses SMP. Without skirts equipped i have 45FPS with spikes to 50FPS with both versions. With version 1.24 im beetween 36FPS and 45FPS with all skirts equipped. Funny detail with the first four skirts im loosing 1FPS per skirt and 5FPS for the fifth. Doens't matter if a npc or the player character is wearing the last skirt. Doing the same with Version 1.29 i'm getting 30 FPS with four equipped skirts, equipping the last one get's me down to 15 FPS!
@Ruedy2000, which skirts? Which mod option are you using? (AVX, AVX2, CUDA...) If you answered CUDA, what video card do you have? Either way, what CPU do you have?
(And some longshots) How much RAM do you have? (If it's more than 8GB, answering "more than 8GB" is a sufficient answer) Did you try running the game without your web browser running? Have you done a recent viral scan?
Hi, I thought I would chime in here. Don't know if this will be helpful, but I'm running an interim potato system, new upgrades in January. The chip/Ram are 7 years old, lol yeah, but I have an early upgrade, a RTX 3080 (cpu choked). I stumbled upon your page the first day you posted and decided to try it because I had nothing else to lose.
My chip being so old, I decided against the Intel instruction code, I didn't need to stress it more, so I kept checking back. Then the first available CUDA (3080) dropped, launched back into game and ran into a large platoon of NPCs from Skyrim At War mod with all of it's addons (glutton for punishment), seconds later CTD. Tried it again same story, disabled, back in again no CTDs, but the same story of severe FPS drops, stuttering in busy cells, which I grew accustomed to on this temporary system. So I gave up defeated lol.
I checked back in again and saw there was a new CUDA build, oh why not! I have a player home just outside Whiterun, stepped outside, smack into a full battle going on ...no CTD, no stuttering! I am getting 36 fps outside (no ENBs) and 6o frames inside, it was honestly like night and day. I disabled the build, went back in and all the misery returned, so it is the current CUDA build that is responsible. I know I'm an extreme case, but man you folks are doing magic, it took stress off my old cpu, which in turn put it's resources elsewhere. I can't wait to see what it does when I throw the new Intel chip/ Ram at it. It can only get better. I haven't tried the NOT-CUDA branch due to being thankful for what I have for now. Anyway just wanted to thank you and your team.

Disabled cuda on the cuda version seems as stable as the no cuda version.
AE 1.6.353
AVX2: ~70 FPS
AVX2 + CUDA: ~60 FPS
CUDA on seems to consistently drop FPS by around 10. In heavy drawcall bound situations (12k+) this increases further to ~15 FPS drop.

NB: I don't know your modpack or your resolution, but your fps are fairly low, do you know Free FPS?

Also, When I equip a non HDT hair, it shoots to 45-55fps in whiterun. Dint999's 18d hair, the longest one, seems a heavy wear xD
Small inn's or caves, mostly are 50-60fps with HDT hair on my head.
But I guess you are right with your assumption that the overhaul is the reason - I think 8k textures are killing the vram.
Even my 3090 with 24gb doesn't like 8k everywhere so I lowered Illustrious Whiterun to 4k and fps is up to normal again.

1.29 should be a lot lighter at low fps (between 10 fps and 60 fps) :/

After many tests with other SMP sets i decided to remove the COCO outfit because it had other flaws, too.
I estimate that I'm running at about 10% slower using CUDA + AVX2 mode vs noCUDA + AVX2 mode.
Just to be sure, did you ran the CUDA version with CUDA disabled?
Please focus on the "Day" versions in the Fomod, I built them from my branch, so I know they're exactly similar, and how they were built.
The goal of this discussion is to decide if I can stop maintaining and building the NOT-CUDA code branch, and focus on the CUDA code branch.

I'm quite happy that this proves this CUDA code is useful to some users
I won't ask you to test the CUDA disabled vs not-CUDA, it would be misery again.
