HI,

 

I should be very grateful for some advice because something very weird has happened. I no longer have the checkbox for the DX-10 preview mode. It was there yesterday and now it has disappeared and I have no idea what might have caused this. I have experimented with DX-10 in the past but without much enthusiasm. Yesterday I decided to have another go and ticked the check box (which was then present) closed down FsX and restarted it. To my surprise FsX would not start, the opening screen would appear and then the programme would just close down. I deleted the fsx.cfg file in order to regenerate it, which worked, but on re-starting FsX I discovered that the DX-10 checkbox had disappeared. What is so odd is that I have run FsX in DX-10 preview mode in the past without any problems and between then and now I haven't changed anything. I have no idea what or why this has happened and I should welcome any help.

 

I'm sorry if this has been covered before, I have hunted around but I couldn't find anything on this problem.

 

Regards,

 

Adam Mills.

Probly the easiest fix would be to just re-install SP2, Adam. Come back if that doesn't do it - ok!

Thanks for your reply.

 

I have Acceleration and I had re-installed it but that made no difference - still no DX-10 option. I also tried rebuilding the fsx.cfg file and that didn't work either so I am stumped. I have also downloaded the latest Nvidia drivers and that too accomplished nothing.

 

Regards,

 

Adam.

Hi,

 

I have just fixed the problem! I found some uneeded dll files fromFxaaTool in the main FsX folder. I removed these and now the DX-10 option has returned. This is a great relief since I was not looking forward to re-installing FsX.

:Party:  :dance: 

 

 

:LMAO: 

OP, what .dll files did you remove? I am having the same problem

There's only the one dll, Raptor - the dxgi.dll. The whole FXAA installation should be removed, and the shaders10 cache deleted and then the system restarted before installing any other shaders files/folders. This one has it's own shaders.hlsl and an injFX_Settings.h, plus the FXAA_DX10 folder - all should be removed. This is post-processing, and can be well handled by the newer SweetFX if some view enhancements are needed - and even then - SweetFX can cause it's own conniptions!

Paul, I think SweetFX is giving me the problems. I found out the d3d11.dll module that I manually placed in there to fix my d3d11.dll module (and FSX) crash is causing DX10 to no longer be displayed.

 

So I removed that and I have DX10 back, but now my sim crashes every time (randomly) because of said .dll

 

I'm lost

Check your Windows Update history, Raptor, looking for KB2670838. This update causes a d3d11.dll crash. Un-install it and your problem should be fixed.

 

Now - what do you mean by "the d3d11.dll module that I manually placed in there to fix my d3d11.dll module "???  SweetFX has no d3d11.dll.

The KB2670838 update caused all kinds of problems on my Win 7/64 system; everything from keeping Windows Live Mail from starting to keeping FSX from starting as well. Took me a while to track it down as the culprit.
