FFXIV DLSS4 FSR4 XESS Mod - Dawntrail

How does this work?

Dynamic resolution scaling is always enabled in Dawntrail and there's no way to change the default DLSS preset. Using a tool called OptiScaler we can restore the default DLSS presets and disable dynamic resolution scaling. I'm also updating the DLSS version shipped with the game to support DLSS4. For everyone else this mod adds FSR3, 4 and XeSS. FSR4 can also be unlocked on most GPUs but runs a bit slower than FSR 3. OptiScaler also unlocks DLSS on GTX 16 series cards by default.

If you are not familiar with the presets, they go as follows from fastest to best quality:

ultra performance, performance, balanced, quality, ultra quality and DLAA (called NativeAA for FSR/XeSS).

Installation:

1. Download and unzip this mod, move all the files in to your FFXIV Game folder. (See path examples)

2. Go in to the included presets folder and rename one of the ini files to OptiScaler.

3. Move your renamed OptiScaler.ini file in to your FFXIV Game folder folder.

4. Now launch the game and enable DLSS. (For FSR and XeSS your GPU is being spoofed and appears as a RTX 4090 to unlock the DLSS option)

5. And that's it you are good to go!

Note: DLSS Presets are broken and require you to switch to FSR and back to DLSS in the ingame settings to work correctly. (DLAA works fine as is)

- To unlock FSR4 on any GPU go in to the Presets\FSR4-On-Any-GPU folder and copy amd_fidelityfx_dx12 and a FSR4 preset in to your game folder.

- You can open up the optiscaler overlay by pressing insert ingame.

- Upscaling is known to not work correctly in the intro and character screen.

- Dynamic resolution scaling doesn't work correctly with the optiscaler.

- You can manually update optiscaler by grabbing the latest release and rename the optiscaler.dll file shipped with it to winmm.dll and move it in to your game folder.

Steam: C:\Program Files (x86)\Steam\steamapps\common\FINAL FANTASY XIV Online\game

Reshade support:

Depth is reversed in dawntrail so you must enable that in your reshade preset. Use gposingway instead of reshade rest, it come's with UI shaders and works just fine once you select the proper depthbuffer in reshades addons tab, it's always the first one in the list see here. If you don't want to use the whole package just copy KeepUI_FFXIV.fx in to your reshade shaders folder and enable it ingame.

XivAlexander Support:

1. Install it in dinput8.dll mode, that's it, d3d9/d3d11 is not supported and might cause crashes.

Linux/Steamdeck/Mac support:
