This is useful when running Turtle WoW on a modern high DPI monitor, on which the game itself runs fine but mouse cursor is hard-coded as 32x32 which would be too small.
You could download a modified d3d9.dll from https://github.com/allfoxwy/dxvk/releases
For Windows 11:
- Put d3d9.dll under the same folder with WoW.exe
- If you using WINE, you could put d3d9.dll into WINEPREFIX/drive_c/windows/system32/
- If you using Proton, you could put d3d9.dll into Proton_Directory/files/lib/wine/dxvk/
- WINE may need a DLL override via winecfg to mark d3d9 as Native. Proton don't need this.
I tried to ask if upstream would accept such mod. He said gamescope already have cursor stretch capability. I think he is right. So I'll post my solution here as an alternative.
