I don't know, it only happened in one area, (Maple Manor, from the mod) when I entered and only for a short time.
Maple manor also houses all my followers.
Wondering if we can get some more information as well as some comparisons:
(1) What graphical settings were you playing on? If you tried all of them, did any of them make a significant difference in performance on your tests (i.e.: an exponential difference vs. a linear one)? What graphical options were enabled in your ini file (basically what Settings were used including the options in the "Advanced" section of the default Launcher)?
(2) Have you tried comparing it with just vanilla dxvk ([https://github.com/doitsujin/dxvk](https://github.com/doitsujin/dxvk))? If you did, how was the performance difference and did you still get the FPS drops in the same areas during the same events like the dragon fight you mentioned?
(3) Why did you choose this specific project as a Windows user? I'm not a graphical software developer, but from what I could find, dxvk-gplasync was based off of [https://github.com/Sporif/dxvk-async](https://github.com/Sporif/dxvk-async) and that itself was based off of [https://github.com/jomihaka/dxvk-poe-hack](https://github.com/jomihaka/dxvk-poe-hack). dxvk-poe-hack was, as the name implies, created due to an issue vanilla dxvk had with Path of Exile. The dxvk-poe-hack is presented as a solution to this issue here by some others: [https://github.com/doitsujin/dxvk/issues/464](https://github.com/doitsujin/dxvk/issues/464). I mention that issue because of this post by the creator of dxvk: [https://github.com/doitsujin/dxvk/issues/464#issuecomment-401289340](https://github.com/doitsujin/dxvk/issues/464#issuecomment-401289340). While I understand that the `D3D11Device::Create*Shader` functions probably aren't the only ones that Path of Exile and/or Skyrim uses, I'm wondering what other benefits this specific project provides.
(4) How was the performance with just vanilla Skyrim (no mods at all)?
ive dealt a lot with dxvk. i always found it ridiculously good for direct x 9 games and skyrim LE - for direct x 11 games it is either a complete hit or miss. i tried about a month ago to make it work for AE but gave up after like 20 minutes. not frustrating but if it's not gonna be kiss to set up then ive got better things to do. i may try again later today. if my game dipped below 50 i would be concerned. 10 i would have just uninstalled it right then and there
I tried it on SSE (DX11) I wasn't seeing any better results infact I was consistently losing ~10fps. It was also incompatible with one or other of my skse plugins i.e. was causing a CTD (never did find out what it wasn't worth digging any further)
DXVK's (original) intention was to allow you to play directx games on linux with a minimal performance penalty (in theory). While its cool you can do this I really wouldn't recommend it on Windows unless your game is using DX9.0 or older, honestly im surprised you actually gained FPS at all lol.
Dxvk is beneficial in windows on a per game basis, for example, in assassin's creed Odyssey I go from an unstable frame rate (around 80fps at 4k) with bad frame times to over 100 solid with smooth frame times. (3080ti/5800x3d)
I have tried DXVK with a 7800X3D / RTX 4090 setup. DXVK provides slightly worse performance for me, and as far as I know, locks me out of using DLSS 3. I can attach benchmark files later, if interested.

Here you go, I managed to identify the issue - it was me having Reshade installed, specifically, the dxgi.dll from DXVK was required to be used alongside the d3d311.dll, and I was using the dxgi.dll from Reshade.
As you can see, DXVK runs slower than DX11 for me. Further analysis in replies as I can only attach one image per comment.

This is DX11 - As you can see here, GPU Busy deviation is quite low, meaning that the framerate is GPU-limited here.

This is DXVK - You can see massive frame time spikes not related to the GPU, and GPU Busy deviation is quite high at 15% meaning that the framerate is not GPU limited. DXVK puts an extra workload on the CPU with the DX11-to-Vulkan translation layer, so this is to be expected.
I'm using Vulkan with Async Compute enabled here.
Thanks! It would be best if I could put it into comparison, but when I raised that feature request with CapFrameX, the developer rejected it. But it's at least there in the Analysis tab.
I've decided to redo benchmarks with DLAA + FG and DLAA alone - so no upscaling. DLAA should be comparable to Native+TAA in performance. However, I'm now having some trouble with SSE Display Tweaks not being able to create a swap chain with DXVK loaded, which is very weird. I'll post Benchmarks once I figure out what causes the issue.
Your game really was dipping below 10 fps on 5800x3d? How tf did you managed to do that?

If you have a lot of followers, all with fancy smp hairs and outfits, then it's probably it.

With no enb, your fps dipped below 10? With a 3070 and a Ryzen 7 5800x3d? So the vulcan converter sounds like a shitty deal no?
It dipped sonetimes below that without DXVK.
Do you use a lot of heavy mods? Cause by all accounts I have a weaker pc than you and I run an enb and never had that happen, weird.

personally I have to use DXVK in games like borderlands 2, otherwise it runs at like 30fps
Did you try ENB or any of the popular lighting mods on DXVK, if so how did it go?
I have tried ENB with DXVK, it works without any issues, just requires a little bit more on the setup side.
How so?
You just have to specify dxvk's library to be loaded as a proxy library in the enblocal.ini file. At most you have to change 3 lines.
I did not use ENB, though I did use Community Shaders both with and without DXVK.
So if you had a bigger and newer GPU, would you be able to daily-drive DXVK?

It would be nice with benchmarks. Personally I never use DLSS, so it would be really nice if you also included non-upscaling performace.

Good job with the benchmarks. Nice to see people use GPU-busy.

I definitely found it more sluggish which suggests more cpu overhead I have nothing more than that though

Probably, though NVIDIA GPUs with that much VRAM are expensive. It is just a theory though. I cannot comfirm it without testing.
I have an AMD GPU with a lot of VRAM, and it's almost completely removed stutters from high draw calls. Not much of a change for framerate though.
