Hi

it seems that with the fixes DX10 runs well now

 

so which is the best for FSX, DX9 or DX10 ? is it worth to try DX10 ?

It is worth a try. DX10 works very well and, in some cases, better than DX9. There are some performance increases with DX10 but not enough to justify moving to DX10 alone. I have no scenery or aircraft incompatibilities but some have seen problems with old FS9 programs as FS9 was never developed for DX10. To fix those, one has to run a program called Addon_Converter_X which makes programs compatible with FSX. FSX developers will not honor any request to fix DX10 issues with their products as DX10 is not a final product. I can understand that. Installing Steve's Shader Fix will not touch your DX9 FSX installation. It fixes most of the issues like flickering taxiways and runways, and you can now see progressive taxiing arrows. The DX10 Shader fix only changes the DX10 folders that are used only if you use DX10. It will not harm any of your DX9 installations. I can use DX9 and DX10 using the same FSX.cfg and NI Display settings. One of the benefits of DX10 is the ability to see shadows inside the cockpit. I think the water and scenery looks better too but that's all in the eye of the beholder. It's free. It came with Acceleration and SP2.

 

Best regards,

Jim

In my case, after 3 days of testing, FSX in DX10 with Steve's Fix was too unstable, crashing in various situations. Better fps overall (not much), bloom effect with no FPS hit at all and better looking water on default (FS Water Configurator doesn't support DX10) are a plus, but instability and some not working addons (scenery/planes) are huge turndown, so no DX10 anymore for me.

I experience much better performance with DirectX 10, especially with exterior/wing views. I haven't experienced any serious issues other than the missing lights at FlyTampa Vienna, but that is not enough to cause me to switch back and lose the performance gain that came with DirectX 10.

Hi @Jim !

 

You can say it´s absolutely safe to try DX10 so you can switch back to DX9 at any time without harm your installed scenery/ac addon´s ?

Could you lead me to the correct thread/tutorial here please ? Thank´s !

after 3 days of testing, FSX in DX10 with Steve's Fix was too unstable

 

Sorry to hear that. DX10 for my rig has been incredibly great.

Thank you @sargeski !

That's interesting. Hardly anyone has reported this. Paul (PJ) is very good at helping people fix their problems. Did you report those crashes in the DX10 Forum? I would be interested in seeing some of your crash reports. Could you download and install AppCrashView - http://www.nirsoft.net/utils/app_crash_view.html and show some of the crash reports? (All of your Crash Reports remain on your system from the date you installed Windows unless you somehow delete them through an external program. This could help others if they are having problems. Most likely you did not install the fix properly. It is very difficult for some, including me. PJ has a complete Shader10 General folder complete with all the changes and fixes so you don't even need to run the install program. All you need to do is download the folder and replace your current folder with the one fixed by PJ. He even backed upped the General10.fx for ya.

 

You still have to go in and delete the cached folder as per the directions but that's it. Go fly. If you like your DX9 FSX.cfg settings, I would simply enable DX10 Preview, shut down FSX, restart and go fly. Some people have made changes to their config. I haven't and, like I said above, I can go from DX10 to DX9 without any problems or modifications.

Jim

Thanks Sargeski for the help!

Who knows, maybe I tweaked FSX.CFG to be unstable during DX10 testing, I can't be sure. I know that I was flying with Airbus X during that testing, and it is knows that addon is unstable, maybe even more in DX10 mode.

Switching to DX10 with very stable and very good DX9 FSX.CFG that I'm using at the moment is worth a try. I'm currently using 310.xx nvidia drivers with my 560 GTX OC version.

 

Thanks Jim for a heads up!

Glad you're going to try it again. No harm no foul....

 

Best regards,

I was digging dx10 but found out my flytampa KBOS airport would not show up properly thats the end of dx10 to bad.

I just finished a week long conversion from DX9 to DX10. It was a frustrating journey at times but, with the help of Paul J and others on the DX10 forum I did successfully complete the conversion.

 

My standardized test flight with the default Baron 58 over Seattle. From West Point -> Elliott Bay -> KBFI -> KFRNT at 2000' and 165 knots with Locked Spot view ORBX PacNW / GTX / UTX / Rex. Fraps (140 seconds) measures the following frame rates (FPS locked in FSX at 30):

 

DX10 24.1 avg / 18 min / 28 max

DX 9 18.8 avg / 13 min / 24 max

 

This is with pretty aggressive scenery settings:

Global Texture - Very High

LOD Medium

Mesh 100%

mesh Resolution 5 cm

Texture Resoultion 30 cm

Water Effects Mid2.x

Scenery Complexity Extremely Dense

Autogen Sparse

Cloud Draw 70 miles

Cloud Coverage Max

NO AI traffic

 

In DX10 mode I reduce the frame lock to 24 FPS and increase LOD to the max value. The average FPS drops to 23.2 (-.9) but the min increases and the max only drops to 25. There is a noticeable improvement in distant scenery and there is no blurries or delayed texture loading.

 

AND - using Process Explorer I see that three of the four core processors stay above 92% busy ALL the time and the third is usually about 80% busy and the texture loading task seems to use three cores pretty much all the time.

 

I am very impressed with the DX10 improvements, particularly when combined with the big improvements in nVidia drivers since 196.

 

BUT - to make DX10 really work - I had to carefully implement Paul J's DX10 fsx.cfg and nVidia Inspector recommendations. I thought I understood the .cfg and nVidia settings pretty well and did a lot of experimenting with them. But, following the Paul J recommendations increased the average FPS about 3 and eliminated the few blurry problems I had.

 

The last thing I had to do for my PARTICULAR software/hardware configuration was turn off LandDetailTextures in the FSX options - I had to uncheck that box because there was some texture being loaded that caused shimmering in the tiles close to the aircraft. I eliminated ALL non-default textures and except ORBX and UTX but still had the problem. I do not notice any loss of image quality with LandDetailTextures unchecked.

 

It is very easy to swap back and forth from DX9 to DX10 - I have a fsxDX9.cfg and fsxDX10.cfg files and just rename the one I want to fsx.cfg just prior to starting FSX.

 

Some aircraft, mostly shareware on my system, have texture or operational issues under DX10. The two disappointments for me are the PA-18 Piper SuperCub which has some VC texture issues but flys nicely, and the Morane Saulnier MS-760 which won't start it's engine in DX10.

 

I highly recommend making the effort to use DX10 - I am very impressed with the results

I just recently did the switch to DX10 as well. As Jim mentioned, one the advantages is the ease by which you can revert back to DX9 if need be (don't think I ever will though...!).

 

These are my initial observations:

- Performance is improved when comparing against the same settings in DX9. In areas of high complexity (e.g. flying into or around high-traffic airports) the sim maintains a higher average framerate which translates into a greater smoothness and fluidity

- Haven't had any instabilities yet with DX10 (with or without the patches); it does seem to allow greater headroom to tweak and push your hardware, and has eliminated the scenery spikes and artifacts from DX9 (YMMV)

- Making the switch is only a 3-4 step process. I also installed Addon Converter X which seems to do exactly what it claims to.

- I did have to read through the how-to and AA guide a few times to understand how to correctly set up AA (e.g. "enhance application settings" vs override). I also learnt (the hard way!) that the MultiSamplesPerPixel setting is tied to the chosen AA setting. Things were gravy after I got that sorted.

- Though enbseries doesn't work in DX10, I've rediscovered bloom and it does look brilliant with REX skies.

 

Tweaking and testing to continue...

"Addon Converter X w" did nothing to convert flytampa kbos unless I'm missing something.
