This started as a blog about Microsoft Flight Simulator. As I investigated why the DX10 Preview option didn’t work properly it then became almost exclusively about improving the DX10 experience. The blog posts describing the early DX10 experiments can still be viewed in the archives.

Ultimately I released a product DX10 Scenery Fixer to address these issues and the blog is now almost exclusively about that product and its development.

To recognise this I have reorganised the blog and you can access pages about DX10SceneryFixer from the menu at the top of the page, read its reviews, learn of its functions and if you wish you can even find a link to an external site where you can purchase it.

Thanks for reading!

    Hi. Where do I download a new copy? I have my info but the link is long expired?

  2. Jon Heinlein says:

    Oh, hi. I have a really old version of Steve’s DX10 Fixer: [DX Controller v2.11 , build 77 ] and I am having trouble with NVIDIA Inspector and its frame rate limiter setting (exception error , unless I choose “unlimited” ) . Is there a newer version of Steve’s DX10 Fixer I can download or do I need to purchase Steve’s DX10 Fixer again ?? (I suppose I can try to revert back to NVIDIA Inspector Thank you for your reply !

  3. stevefsx says:

    If it said warning not installed then the libraries weren’t installed, have you changed the fsx location? I suggest installing the libraries then uninstalling them again.

    G’day Steve, i have just installed DX10 Controller into my FSXSe. I have had an issue with the Traffic Toolbox today, and as part of my investigation noted that a file called DX10SF_dll.xml has appeared since installing. I see it contains similar information to my FSX dll.xml file. Can you explain its use please as I am trying to distinguish which file FSX uses in its boot stage.

    • stevefsx says:

      DX10SF installs 3 libraries that it uses, that is one of them. If you uninstall the libraries from the controller then you can test without the fixer and reinstall the libraries to add them back in

      • Andrew STAFFORD says:

        Thanks Steve,
        So I uninstalled the libraries from the Fixer “WARNING!! Not Installed” and still got the error. Does this suggest my original files are the issue as It appears to not have changed the FSX dll.xml file.

  5. Corey McDonald says:

    I am pretty sure I have purchased this in the past. can someone look up order information for me?

  6. phdx1 says:

    Hi Steve. Just trying to install my DX10 fixer purchased from FSS but the online activation does not work anymore. Can you advise on how I can get the program up and running? I have my order number and code etc. Thanks.

  7. Shtaket says:

    Hi Steve
    Can you ask for my purchase details to be sent again

  8. Rob says:

    Hi Steve, Just getting back to FSX (having winter is sooo nice). Originally purchased DX10 at Flight1. I still have all the information, just need to update. Not sure how to proceed.

  9. cessni says:

    Hi I need new download links for the fixer and the cloud shadows. Would you be so kind to email them to me? Thanks!

  10. gentlereader2014 says:

    Hi Steve,
    Could you post the steps for a reinstall? My purchase is from 2016, and I changed the HD, so I am reinstalling everything anew at the moment. Thank you!


  11. Julian says:

    Hi Steve, I just purchased the fixer (DX10 working before purchase). I was able able to install it but after installation FSX won’t load, the issue is exactly like you described in Version 5.3 “The first problem was a FSX load error after the libraries were installed that prevented FSX running. The problem here was that I had accidentally created a reference to the latest version of the DX10 DirectX libraries (June 2010)”. I have version 5.4 build 156, I would really appreciate if you can help me with this issue, thank you!

  12. Matz Fischer says:

    Hallo, ich habe das Produkt vor Monaten gekauft, aber ich kann die E-Mail nicht finden die den Schlüssel hat, würden Sie mir einen Schlüssel auf meiner E-Mail-Adresse bitte zu senden?

    • stevefsx says:

      Ok I am back at my home computer and have managed to locate your order – it dates from 4 years ago which is why I couldn’t find it when looking for a recent order. I have reset the download and resent you everything that you need.

  13. Tarik says:

    Hi Steve, would it be possible for me to email you about my issue with FSX? It would be much easier than trying to explain it here as I am not 100% sure your fixer can necessarily help me out.

  14. Mikko P says:


    Can I get much better graphics with your fix/dx10

    I have fsx se and rex4 clouds/rex4 enhanced textures

    Game is rolling good, but graphics are little bit “porridge”

    My computer specs are:
    GTX 1661ti
    16gb ram

    • stevefsx says:

      The fixer fixes issues with the fsx dx10 implementation such as flashing runways, untextured objects. This allows you to have shadows in the virtual cockpit which the dx9 engine does not support.

  15. William A Campbell says:

    Hello I just purchased the DX10 Scenery Fixer but only got the download link for the addon of the cloud fixer I put on at the time of purchase. I really would love to use this program but I need the download of the actual program. Thank you for any help provided in advance.

  16. Ed Kammerman says:

    Hi Steve,
    I purchased DX10 Scenery fixer a few years ago from the Flightsim store. Well I redid my PC recently and totally wiped my drive that had the installer on it DUH !!! If you could send me the necessary info and a link to the installer I’d appreciate it, I have my license info but not the order info.

  17. WallysWorld says:

    Hi Steve,
    Finally decided to install your DX10 Fixer after procrastinating for a long time and I can’t be happier. FSX runs better now, I can turn the LOD up and the graphics are improved And I just added the cloud shadows today and fantastic! Thanks for making these two programs. They really breathe new life into FSX.

  18. Manecas Cris says:

    Dear Steve, Rui here, from Portugal. Just purchased your Direct X fix because all I really wanted was the clouds shadowing the ” earth down below” 😉 as I “fly along”…:-)
    well, Sir, it was money well spent, now I have old models ( and I mean old,) I still love so much showing up, I have the Sun embracing my cockpits giving me a whole new flying experience, ( great shadowing effect!) and my Clouds just gained a new life, my FSX looks absolutely gorgeous, just had to say thank you Sir, for a great product! Love it! 👍 Stay safe!

  19. Oscar says:

    Hey Steve, I have a scenery that had many problems with DX10, when I turn it on, the scenery turns white.

  20. Blake Matthies says:

    Hey Steve, I just reinstalled fsx and I lost my license code for the fixer…i have the activation code for Clouds, but not the fixer…can you help? Purchased at the FlightSimStore…

  21. dimidrol231 says:

    Hello Steve. Using DX10FIXER deal with ground texture missing – they are like water surface. What can you advise? P. S. in DX10FIXER menu water button is not available

    • stevefsx says:

      Yeah, if you use the diagnostics button it will tell you that the water shader is not the original. You need to install the original fsx water shader. If you cannot find it then you can get a copy from nzfsim here https://www.nzfsim.org/fsx-p3d-tweaks/dx10-fixer-for-fsx/

      • dimidrol231 says:

        Thank you for quick response. Ok, will try. But I have never downloaded any water shaders (but I have AS16) and FSX texture were okay until computer restart. And one more thing : when DX10 fixer is deleted from PC everything with ground texture goes smooth. Could this problem be connected with AS16?

      • stevefsx says:

        if the button is greyed out as you describe then the water shader has been altered and will be reported by the diagnostics button. In that case uninstalling the fixer libraries will behave as you describe. The most common reason is installing the dx10 version of the fswc tool. Just reinstall the fixer, install the libraries and run diagnostics.

      • dimidrol231 says:

        The main problem for me is ground texture like a water. How does water shaders connect with ground texture problem? And as I understand to solve it problem I need download shaders?

      • stevefsx says:

        Look it’s very difficult for me when you haven’t run the diagnostics button which checks everything and I am trying to guess from a description of a greyed out button, and a description without a picture. If the land textures are not there the. There is a problem with compiling the terrain shader. Can you run the diagnostics check that I asked and then send me an email to the support email address in the front of the manual.

      • stevefsx says:

        This was resolved

      • dimidrol231 says:

        Ok,thank you. I will do it as soon as possible.

  22. Kaiser says:

    Hi Steve, I would like to test on my Pc the DX10 Preview mode, could you kindly send me the link?
    Tks a lot.

  23. Walter Davidson says:

    Hi Steve, I have been enjoying both your DX10 fixer and cloud shadows. However I have some problems trying out shaders for FSX (not reshade 3). Specifically reshade 2.0 and enb series. However while having the shaders installed FSX causes a BSOD and my computer has to restart. Any suggestions?

    • stevefsx says:

      Try uninstalling the fixer libraries and see if it works then. I recall reshade had issues with older fsl spotlights versions. I don’t test compatibility with reshade etc

  24. Anonymous says:

    Hi Steve just purchased DX10 fixer can you confirm and send next steps thanks

    • stevefsx says:

      You should have received an email from fastspring with the download links and license within 5 minutes of purchase. Check your spam folder, if you cannot find it then let me know, but you need to supply a name or email or orderid so I can locate who you are

    • stevefsx says:

      Everyone who purchased today has now downloaded so I am assuming that you located the email.

  25. Hello Steve fsx I have scenery fixer very good program
    but I have cleanup my gmail and i have deleted the mail with the scenery fixer licence

    Almost thanks.

  26. David Graham says:

    Still waiting for the fix? Payed for it 24 hours ago? Anyway to have automated system were we get the product?

    • stevefsx says:

      It’s a fully automated system operated by fastspring who are a multi million dollar software delivery vendor. You should have received the email within 5 minutes. Can you check your spam email folder? I will notify fastspring and ask them to resend. Occasionally there are strange issues with email delivery.

    • stevefsx says:

      I have corrected your email address ( you had missed out the p) and resent you the corrected order details.


    Good evening Steve,

    6 years ago I bought DX10 fixer at flightsim store, after uninstalling FSX I stopped using it three years ago. Now I am back to FSX. I kept a copy of the DX10 fixer, the activation key, etc., but cannot activate it.

    Is it possible to reactivate the product or should I buy a new copy?

    If you need details of the invoice, I will send them to you.

    Thank you

  28. Donald says:

    I went to the sim store to download my 3.4 copy but it isn’t working. I had to reinstall my fsx from building a new computer.

  29. Drumond de Melo says:

    Hi Steve, good afternoon!
    Old customer from FSX returning to the activity. As you mentioned, my 3.4 installer doesn’t work.
    Would you be so kind to send me a replacement installer? Let me know if you need any info by email.
    Thank you and best wishes.

  30. Gord says:

    Hey Steve, does Fastspring still work for the latest updates, I’ve been unable to Fly less for almost a year, -Gord

  31. Josh says:

    Hi Steve, I tried downloading ORBX GLobal Base Pack but it has black squares on the street lights, I also tried using DX10 Fixer, but it still won’t resolve it, please provide a fix thank you.

    • stevefsx says:

      I cannot find an order in your name. Are you sure that you have purchased an downloaded the DX10 fixer? Are you perhaps referring to the free shader patches from 2012 that came before the Fixer was launched? If so then they fix only a very small number of issues such as flashing runways.

    • Euan Domloge says:

      Hi Steve

      I cannot get anti aliasing to work with dx10 preview, your software, and nvidia inspector. I have followed many online recommendations for inspector settings – are there specific settings I need to have in place? Or a specific version of inspector. Nothing is working. Thanks.

      • stevefsx says:

        Select 4x Aa in dx10 controller. Then select 4x Smart Grid Super Sampling in Nvidia inspector. Ignore free flight window as no AA applies there. No other settings have any effect on AA but those two.

      • Euan Domloge says:

        Ok thanks I’ll try tonight. One last thing – it is a laptop with an nvidia gt740m – can you think of any reason why this card might have a problem with your software? Thanks again

      • stevefsx says:

        This has nothing to do with my software.

        That is a fairly low end card so you may not be able to run super sampling with it at reasonable frame rates.

  32. Michael says:

    Steve: I bought the Fixer a number of years ago. I have the original emails, codes, etc. here on file. Can I still download the program if I give them my credentials? What do I have to do?

  33. jacques duchemin says:

  34. LIEGEOIS Joel says:
