How to properly override DLL

[TempuraShrimp]

Hello and good evening. I'm new to Wine and just finished installing my first game with it (The Witcher: Enhanced Edition). I noticed quite a lot of graphical artifacts indoors, so I went to WineHQ to search for possible workarounds, and the issue seems to be related to the d3d9x_35.dll used by the game. (As seen here https://bugs.winehq.org/show_bug.cgi?id=46553).

Anyway I tried overriding to the native DLL using winecfg -> libraries, but the game crashed on startup. Tried downloading the DLL using the commands

Code: Select all

winetricks d3d9x_35.dll

and

Code: Select all

winetricks d3d9x

, and the terminal output said something about it setting the DLL for override. Then I tried to override it again through winecfg, but the game still crashes on me.

The bug report describes the exact same issue I have, so I think I must be doing something wrong. I'd appreciate any help, thank you in advance

winetricks should set the override itself. The name of the dll is d3dx9 though unless you made the typo only in your post:

Code: Select all

winetricks d3dx9_35

Yes, that was indeed a typo. Anyway I finally figured out how to solve my issue!. Turns out TWEE is a 32-bit only program, so it was just a matter of placing the corresponding 32-bit DLL file beside it. I think Winetricks might've had tried to override d3dx9_35 with a 64-bit version of the DLL though. I wish the bug report would've had been more specific regarding this.

Just to be sure, would Winetricks have installed the 32-bit DLL file automatically if I'd had used a 32-bit Wine prefix?

winetricks should have installed both the 32- and 64-bit dlls. It's always possible there was some weird issue somewhere though and sometimes it's easier / safer to use a 32-bit prefix. But if things are working don't worry about it.
