How do I get reshade to work for assassin creed Odyssey

[✿Sakura Rozu✿]

Anyone knows? Thanks. I been looking for a guide but I couldn't find one.

Sadly the resources that was posted in the Odyssey thread on the discussion board of the game was deleted and lost when whatever moderator decided to perma-ban Kaldaien from that forum due to seemingly fraudulent reports.

I _believe_ some users got it to work, although I don't remember the specifics beyond that Uplay's overlay needed to be disabled (I think). You might want to try extracting the Special K + Custom ReShade package for Monster Hunter World and then extract the Odyssey Special K[github.com] over the files, overwriting the existing files from the MHW package.

That might or might not work.

Thank you I will try that!

Kaldaien packed up the entire custom ReShade base as Unofficial_ReShade.7z at https://github.com/Kaldaien/SpecialK/releases and found under "Miscellaneous Binary Dumps" as a easier to setup alternative and which can work with the game although from my own testing neither 3.4.1, 3.4.1.1 (Modified version by Kaldaien.) or 3.0.1337.1030 (Custom ReShade by Kaldaien.) works with SpecialK without crashing at the first logo video so YMMW.

Worth giving a try but you might have to choose between ReShade or SpecialK if it still crashes on start-up.


The files should go into here I believe.

C:\Users\USERNAME\Documents\My Mods\SpecialK\PlugIns\Unofficial\ReShade

And then in-game you just tick the checkbox for using the custom version of ReShade via the SpecialK OSD and restart the game and it should try to load up the .dll as the game is next started.
(Instead of trying to proxy load a specific .dll by manually editing the config file.)

Prior to having the original thread forcibly removed (bastards!), I managed to succesfully plug in Unofficial ReShade into Special K on my Uplay install of AC:Odyssey. Please note that I had to disable the Uplay overlay to get the game to load, which unfortunately also disabled the Oikos of the Olympians end-game store and any online quests that net you Orichalcum!

The problem I encountered, however, was that having Unofficial ReShade simply plugged into Special K effectively halved my framerate in the same areas I was getting a smooth 60 FPS before, even without any effects actually injected into my game!

I took some screenshots with and without Unofficial ReShade plugged in, which you can see here: http://imgur.com/a/NNbk5jk

Now, I am fairly sure that such a dramatic performance drop is not intended and there has to be some other setting to configure (other than the Special K injection ones) in order to get a nice framerate with Unofficial ReShade. Unfortunately, the original thread got deleted before Kaldaien had a chance to reply... :(

Do you fine gentlemen have any idea why Unofficial ReShade would tank the framerate like that simply by being plugged in through Special K?

P.S. Before installing Special K, I mainly used ReShade to inject some sharpening to combat the bluriness of the in-game AA option. Since I might not be able to play with Unofficial ReShade due to this massive framerate drop, do any of you know how I might enable Negative LOD Bias via NVIDIA Inspector to inject some sharpening that way? Thanks! :)

Nvidia Control Panel has an option to clamp or allow Negative LOD Bias on the Manage 3D Settings page. It defaults to allow, I believe.

[Verrenus]

Thanks for the reply, but I was already aware of the option in the Control Panel. :P

I always use NVIDIA Inspector instead because it offers me access to hidden settings and also more granularity for configuring my game profiles.

I sought your help because simply allowing Negative LOD Bias, disabling the driver’s automatic lod bias control and setting a negative bias value do not seem to produce an effect in-game.

This led me to believe that there is another setting that needs to be switched on/off for it to finally sharpen the textures. :/

[Aemony]

The topic of NVCP/NPI specific overrides rarely comes up here if it isn’t related to the most basic of options, such as the SLI compatibility bits.

I recently reworked the PCGW article for the Profile Inspector and I still barely remember or understand half of what those settings involve.

Anyway, it could simply be that Nvidia’s overrides isn’t compatible with how the game works, since it apparently is more along a DirectX 12 engine under the hood than a DirectX 11 engine. Either that, or whatever override applied is diffused through the dynamic resolution of AA Adaptive, Low, and Medium, or another shader and/or setting of the game.

Thanks for that, now we just need a Assassins Creed Odyssey subforum.

[Verrenus]

Alright, so I managed to force Negative LOD bias to work in-game by applying the following tweaks in NVPI:

- Antialiasing - Transparency Supersampling: 0x00000008 AA_MODE_REPLAY_MODE_ALL
- Texture filtering - Driver Controlled LOD Bias: Off
- Texture filtering - LOD Bias (DX): - 0.5000
- Texture filtering - Negative LOD bias: Allow

While -0.5000 provides some welcome texture sharpening, any values lower than this will apparently bug out the night sky by dimming individual stars (but not the Milky Way galaxy texture) to invisible levels.

This again leads to me to lament the framerate drops I am seeing when plugging in either Official ReShade or Kaldaien's Unofficial ReShade version into AC:Odyssey via Special K...

Before the original forum thread was forcibly closed, I posted the following screenshot comparison of my game with and without Unofficial ReShade plugged in:

Do these drastic framerate drops occur in other games for which Kaldaien configured his Special K mod (e.g. Monster Hunter World) by any change? I have a hard time believing that this behaviour is intended, given how both Official and Unofficial ReShade cause my framerate to tank even when not injecting any effects into the game! :/

Probably has something to do with locking the depth buffer.

The game sets up render commands on multiple threads, ordinarily these threads work independently. Unfortunately, any time one of these threads changes the depth buffer, all other threads have to wait for it to finish. That defeats the purpose of multi-threaded rendering and will kill performance in a game like this.

As long as you don't use an effect like MXAO that needs the depth buffer, unofficial ReShade will skip this locking problem.

Hey Verrenus how did you manage to get reshade working with the game? I downloaded the unofficial reshade and put the odyssey files on top of it and even though reshade is getting loaded there is no difference with it on and off. It looks like it doesnt get applied even tho its loaded. Setting the load order to Early crashes the game.

Thank you very much for replying, but I am actually seeing these massive framerate drops even with NO effect injected whatsoever. Before installing Special K, I actually only used the latest official version of ReShade (i.e. 3.4.1) to enable Clarity, Deband and LumaSharpen, which to my knowledge are very lightweight and do not make use of the depth buffer at all.

Furthermore, it was with your recommended version of Unofficial ReShade plugged in that I encountered these problems, which made me wonder what the problem might be?

First of all, make sure that you disable any overlays (since the Uplay overlay simply crashes my game at launch with ReShade plugged into Special K).

Secondly, the load order must be set to "Plug in" NOT "Early", and all of the Special K injection settings that you can find under the Unofficial ReShade in-game configuration menu must be ticked off before you will see any effects enabled.

I am very curious to know if you are also experiencing massive framerate drops with ReShade plugged into Special K?

Hey thanks for the help, it turns out one of the settings called Proxy DXGI format was set at 26 and i put it to 0 and it worked. I'll play a bit and let you know if i'm seeing any difference in performance.

Edit: Nope, no performance drop.

[Verrenus]

I am losing my mind here trying to understand why ReShade (both Unofficial and Official) tanks my framerate when plugged into Special K.

Without having Special K installed it runs just fine. Apparently I am the only one suffering from this issue! :(

Have you tried removing vsync? If you lose a couple of frames due to reshade and it goes below 60 vsync will drop your framerate to 30.
