Performance Fix [Win10]

Overview

How to restore game performance in Zoom and Fullscreen modes.

Preface

Since the old WineD3D wrapper fix no longer works with the game (possibly due to some Windows or GPU driver update) I’ve decided to write an updated guide. However, if it happens that the fixes proposed here do not work with your GPU, be sure to keep an eye out for new WineD3D builds.

Update (2020/09/14): DxWrapper method has been replaced with DDrawCompat method, since the former also used a DDrawCompat library, the latest version of which can now be used as a standalone.

Recommended Method (DDrawCompat by narzoul)

1. Download DDrawCompat[github.com].
2. Unpack ddraw.dll from the archive into the game installation directory (usually SteamsteamappscommonFortune Summoners).

---

This method provides the best performance and should give you stable 60 fps on High settings. Going deep into sub-menus can still tank the framerate, but it doesn’t affect the core gameplay.

Other things to know:

• Doesn’t work with dual monitor setups.
• If you use a Japanese version of the game with locale emulator and experience crashes, try an older release[github.com] of the DDrawCompat library.
• If you experience distorted half-screen picture with weird colors, go to sotes.exe file Properties, switch to Compatibility tab, check “Reduced color mode” and select “16-bit (65536) color”.

Alternative Method [slower] (dgVoodoo by Dege)

1. Download the latest version of dgVoodoo[dege.freeweb.hu].
2. Unpack the archive into a folder and copy the file
   • DDraw.dll (found in the MS folder)

   to the game installation directory (usually SteamsteamappscommonFortune Summoners).

DgVoodoo in its current state only provides enough performance for Low graphics settings, but it enables Steam overlay. It is also in active development, so its performance may improve in the future. I’m adding this option as a backup plan and in case the recommended method doesn’t work with some GPUs.
