Sudden Crash of SweetFX - Fullscreen to window mode

Recommended Posts

My problem is that whenever SweetFX used in fullscreen and minimized a Window mode, crash happens. The FSX closes suddenly without a trace of the error.

I have done several tests but I have not found the solution. This problem is discussed in many other places, and a few have managed to fix it, many others like me, do not succeed.


I will describe some important points for your feedback:


Testing I've done:


1- FSX.CFG  new file.
2 With or without NVI.
3- SweetFX versions 1.3, 1.4 and 1.5.1.
4 Different configurations sweetfx_settings.txt
5- SweetFX files in FSX main directory.
6- SweetFX files in another directory outside of FSX.
7-A .bat file that automatically deletes the shaders:
RD / S / Q "C: \ Users \ elee \ AppData \ Local \ Microsoft \ FSX \ Shaders"
RD / S / Q "C: \ ProgramData \ Microsoft \ FSX \ Facilities"
RD / S / Q "C: \ ProgramData \ Microsoft \ FSX \ SceneryCache"
RD / S / Q "C: \ ProgramData \ Microsoft \ FSX \ SceneryIndexes"
8- With ½ Vertical Refresh Rate Sync.
9 - No ½ Vertical Refresh Rate in Sync
10- Nvidia Driver 337.88
11- Nvidia Driver 340.52
12-With all the addons in exe.dll ON
13-With all the addons in exe.dll OFF
14-NO Flaps program.
15-NO MSI Afterburner
16-FS Recorder on or off.

17-Pseudo use to prevent from fullscreen to window mode. The crash occurs less frequently, but the problem is there.
