I decided to try, once again, to use DX10. Past attempts to use DX10 have been relatively successful. I did see the increased frame rate but the minor runway shimmering did not appeal to me. Now that there appear to be several DX10 modifications and enhancements I thought I'd give it another try.

 

I have not tried DX10 for many months and have applied a lot of Vista maintenance and have installed and/or removed several FSX modifications including the OOM memory patcher.

 

When I try to start FSX with the DX10 flag set to 1 (d3d10=1) - FSX loads for a while and then the FSX address space just vanishes - no error codes, no warning message, nothing from FSX - it is just gone.

 

I run ProcMon and trace all commands and IO while starting FSX. Following is the last command that executes before FSX vanishes:

Event Class: Registry

Operation: RegCloseKey

Result: SUCCESS

Path: HKCU\System\CurrentControlSet\Control\MediaProperties\PrivateProperties\DirectInput\VID_06A3&PID_0160\Calibration\0\Type

TID: 5060

Duration: 0.0000014

 

I reinstalled DirectX with the most current download from the Microsoft Tech Net. That did not solve the problem.

Dxdiag finds no problem.

I installed the latest nVidia driver - did not solve the problem

I reverted to an nVidia driver that I am sure did work with DX10 - did not solve the problem

 

Can anyone suggest what I might do to get DX10 preview running again?

Problem Resolved!

 

In FSX root directory:

Deleted d3d9.dll - did not solve problem but FSX with DX9 will run

Deleted d3d10.dll - did not solve problem but FSX with DX9 will run

Deleted dxgi.dll - Solved problem and DX10 runs with it's normal shimmer

 

WHY are the d3d9 d3d10 dxgi dlls in the FSX root if they are not needed and FSX uses the ones in Windows/System32?

The .DLL's were left over from your last attempt with DX10 and were not removed.

The d3d9.dll belongs to the ENB mod and is a hacked version of the one in the system folders. If you have the enb.ini in there too, you should remove it. No DX10 related dll's were ever placed in the main FSX folder by default. You or some addon put them there.

 

Best regards,

Jim

Thanks for the info - I had forgotten that ENB installed it - I also thought that I had uninstalled ENB but I guess it or I did not remove the .dll
