OptiScaler version v0.8.2 worked perfectly, but in version v0.10.3, OptiScaler freezes in the interior camera view when using DLSS 5.
It doesn't work on flat screens and VR.
If it worked, it was by accident and this is the 1st request i have for OptiScaler. right now id prefer to wait for dx12 before we do dlss5 with the mod...but will try an enable support for now.
but try this:
set mirror_dlaa = 0 in dlaa.ini (or press Alt+F6 in game), also try preview_dlaa = 0, retry the interior camera. I suspect the mirror work may be interfering.
Whats the OptiScaler fork name and version? can i get an OptiScaler.log from the game folder?
The OptiScaler.log shows it: the mirror DLSS feature (2048x512, HDR) makes the DLSS 5 Neural Rendering model crash the DX12 device (OpenSharedHandle error -7785FFFB = DXGI_ERROR_DEVICE_REMOVED at 16:36:05). After that every DLSS call fails, so the picture freezes. The main 4K picture works fine with DLSS 5.
Keep mirror_dlaa = 0 with OptiScaler for now.
The next version detects OptiScaler and starts with mirror DLAA off by itself (mirror_dlaa = 1 or Alt+F6 still force it on).
Full DLSS 5 support waits for the DX12 renderer or when/if they release it for DX11.

mirror_dlaa = 0 worked. I'm using this version: OptiScaler-NR-v0.8.91-rtx40-mfg.

Yes. I used the other version as well, and it showed the same problem.

I also noticed that the performance of version v0.10.3 is lower than that of version v0.8.2 when using DLAA.

for perf you can try:
perf_profile = medium or low in dlaa.ini.
Alt+F5 switches the per-draw motion vectors off (camera only, like v0.8.2).
but i really need logs to compare both.
dirceujuninhojunior21-rgb commentedon Oct 11, 2026
I tested both versions, and the performance seems to be the same when using Alt+F5.

Nice, check the latest dev build for many perf improvements with that setting: https://github.com/JRDevo/ETS2-ATS-DLAA-DLSS-Injection-Mod/releases/tag/v0.11.0-rc1

New release will check for OptiScaler and turn mirrors dlss off. take a look and let me know.
