Please describe the issue and steps to reproduce it

ZZZ supported only DLSS and I was using OptiScaler with it so that I could use FG and RT with my AMD hardware. A new update was released for the game yesterday and added native support for FSR. However I still want to use Optiscaler to be able to use the latest features of FSR regardless of what the developer implemented.

Before the update, Optiscaler correctly was able to use FSR 4.1.1 as the upscaler (using FSR 3.X/4 as the upscaler setting), however now it only can use 3.1.5 (and 2.3.4) as the upscaler version. So something makes the 4.1.1 option dissappear. Frame generation is still able to use 4.0.1.

I have checked the logs and Opti loads all correct DLLs, so loads in SDK v2.3.0 that comes with OptiScaler and not v2.1.0 that comes with the game.
I have the exact same files in another game (NTE, which also uses DX12) and that does allow me to use 4.1.1. as the upscaler, indicating a ZZZ specific issue? I've also tried without the game-supplied DLLs to check if it maybe did load them somehow, but same issue persists.

I have attached

• OptiScaler.log (set LogLevel=0 and LogToFile=true in OptiScaler.ini, zip it if too big)

OptiScaler.log

• Screenshot of game folder (where you placed Opti)

• Screenshot of Opti overlay in-game (opens with shortcut, default Insert)

Maybe try Opti as dbghelp.dll

No change unfortunately :(

I've also tried executing the game binary directly with the DX12 flag (as before this update, the launcher did not support DX12 mode for AMD) to see if maybe the launcher had something to do with it, but alas same result.

Seems the game still loads OptiScaler just fine tho, as the rest is as intended, just that the FFX SDK is not reporting correctly that FSR4 can be used as the upscaler (I did check and the amd_fidelityfx_loader_dx12.dll is up to date (2.3.0.2740).

[asiebens]

For reference, I've included a log file of another game running in DX12 natively with the exact same files, and does allow me to select FSR4 as the uploader.

Zenless Zone Zero has supported AMD FSR upscaling and Frame Generation natively since version 3.1.

On Radeon RX 9000-series GPUs, it runs FSR Upscaling version 4.0.3 and FSR Frame Generation version 4.0.0. You can simply replace the existing FSR upscaling and frame generation files with the latest versions.Unless you have a specific need, there is no need to use OptiScaler.

[asiebens]

That is indeed what I use now, as using FSR3 is ofc worse than the built-in option. I prefer not to replace the game files (even the DLLs as sometimes that would trigger a redownload if the launcher would check file integrity).

Just wanted to also give notice to the devs that something is making the SDK not report the correct available upscalers. Maybe something to do with the FFX SDK, in which case nothing OptiScaler can do about it.

Okay, after examining the Steam version of the game, this definitely seems enforced by the game devs - gacha devs reeeeally love their arbitrary lockdowns for whatever reason. Tried different combinations, but even directly swapping any of the AMD FSR SDK files, the FSR4 Upgrade is gone.

BUT

I've managed to find a workaround - if you drop in the FSR4 driver binary - amdxcffx64.dll - into the game folder with Opti, then Opti manages to pick it up and correctly apply (reads as 4.1.1 *, the asterisk indicates driver upgrade). Tested it working both directly (even when replacing their SDK files) or through a subfolder as you're using it.

[asiebens]

Oh wow, weird that they locked it down so hard (did not encounter this for any other gacha game so far). Great catch though.

We can consider this resolved then!

Thanks @TheRazerMD for the effort in identifying the problem!

[TheRazerMD]

As far as I know, definitely a new behaviour from gacha games, but also think this is the first one that added native FSR4 support? As everything else, it's probably caused by the anticheat being aggressive enough.
Edit: Updated the Wiki compatibility entry yesterday already.
