Game name and version:

Cities Skylines II 0.6.0f1

Mods and mod versions used

Optiscaler_0.9.4-final.20260718._MM + DXVK 3.1.1

GPU

Intel Arc A770 Graphics

OS

Windows 11 26H2 26300.9457

Used automated or manual install?

Automated
Manual

If on AMD/Intel and Automated, used DLSS inputs?

Also please mention in description which upscaler inputs are used (which upscaler you selected in game settings).

Using XeSS upscaler

Did you check the Wiki and Compatibility List?

Note: Although the wiki states that the game crashes with DX11, on my device it’s the opposite—it only runs properly with DX11, whereas DX12 causes the application itself to freeze.

Please describe the issue and steps to reproduce it

Put DXVK's dxgi.dll and d3d11.dll on game folder and load OptiScaler with OptiScaler.asi or other filename
Game window created and then crashs

Logs:
OptiScaler:
OptiScaler.log
DXVK:
Cities2_d3d11.log
Cities2_dxgi.log

I've searched issues both DXVK and OptiScaler repos, but only found some issues about Linux device and most are stale.
Noticed an issue #907 might make compatiable with DXVK 2.x ~~but I've not tried 2.x yet.~~
Looks like DXVK 2.7.1 doesn't work.

I have attached

OptiScaler.log
Screenshot of game folder
Screenshot of Opti overlay in-game

No yet, I just use DXVK only to replace DX11 for better render performance now.
