DX10 Flashing Runways - Experimental Shader

[Guest firehawk44]

I'd probably try uninstalling shade. It's such an small easy program to reinstall that it'd be worth a shot.

 

I'll try that!

From your directory listing above the shader isn't compiling. I doubt anything else could have much influence on this. Your change looks fine visually. If you put the original general10.fx back, delete shader10 and run fsx is everything then ok?

Well Steve, you made my day ! No more runway flashing ! With DX10 preview enabled, I tried out stock FSX AA which is much better than I expected (if you don't mind some shimmering). Vsync was also fine. No tearing at all, even with TIR. I always thought these two items were broken :Thinking: .

I went to your website Steve and made some modifications to make sure the spacing, etc., was the same then saved, deleted the Shade 10 folder, and had the same problem. Black screen where aircraft preview, a black sky, and black water, and no KFHR. I remove DX10 Preview and everything looks perfect.

 

I deleted the Shade program as suggested by bonchie and still had the same problem. I went back to the default General10.fx and still the same problem. So, for some reason, FSX is not working with DX10 preview loaded. I use NvidiaInspector instead of the display drivers but that shouldn't affect DX10. Truly strange and I'm somewhat computer literate.

 

I'll just monitor this thread and see how others fair with this potential DX10 preview fix. I can live w/o DX10 preview but now I'm really wondering why DX10 isn't working anymore. As you can see in my signature, I have a pretty powerful system. Thanks to you and bonchie for your help! I hope this 'fix' does eventually work.

 

Best regards,

Jim

Nice spitfire!!

 

Fsx Dx10 AA seems fine to me too (apart from the internal shadows which look rubbish).

Thanks Steve for your help. It now works. It's amazing how many more FPS you can get in DX10. I had forgotten. This is a great fix for the flight sim community!

I think now that the flashing is fixed DX10 mode might be a good option for those who truly struggle to run the game good in DX9 mode.. If you have to dial back settings w/ DX9 to get it to run good chances are you're not pushing high SSAA anyway and putting up with some jaggies and shimmering as it is.

 

I just ran a quick test.. DX10 w/ in game AA + FXAA does a passable job of reducing a lot of the jaggies and shimmering to the point it's very playable. I was surprised how well FXAA (I have to use an injector with my ATI card) works in FSX. Still enough of a deal breaker for me though as I have no tolerance for shimmering. Isn't for me and going to stick with Prepar3D as my sim of choice still but it's nice to see a community member finally knock out the DX10 flashing issue as it gives some people with lower end hardware a new life to their game.

This sounds like an interesting development, but is there a technical reason why AA doesn't work when forced from the NV driver in DX10 preview?

This mod worked for me, but overall the performance of DX10 still doesn't hold a candle to my DX9 with 1/2 refresh rate adaptive Vsync through NVidia Inspector setup.

If anyone here has an NVidia card, I highly recommend trying this before settling on DX10 and it's multiple limitations and issues.

 

My frames may not peak at 50 like they do in DX10, but what makes the DX9 1/2 refresh rate adaptive Vsync mode pure gold is the fact there are no microstutters whatsoever.

In DX10 my frames sometimes spike up to 50 depending on where I'm looking, but I can notice microstutters which ruins the fact I got to 50 FPS anyway.

In DX9 I have a smooth, stable 30 FPS 99% of the time with zero stuttering. The lack of stuttering makes you believe you're actually at a higher framerate because of how smooth it is.

 

Anyway, @OP, your mod works. I had zero shimmering in DX10.

Setting Vsync at 1/2 the refresh rate in Nvidia Inspector and locking FPS at 30 in FSX also works in DX10 Preview mode.

LOL, exactly.

NVidia Inspector only works with DX9.

[Jean-Paul 167]

Nvidia inspector doesn't work for defining AA settings in DX10 preview mode but setting VSync at 1/ the refresh mode works...

 

Did you actually try it ?

 

[ajpongress 467]

Yes I actually tried it. My inspector settings didn't change between my DX9/DX10 tests with the shimmering.

In DX10 I had noticeable micro stuttering, in DX9 I don't and everything is much smoother.

 

Everything I've read online suggests Inspector won't work with DX10 since it's not a true DX10 and a preview mode only.

How do you know for sure that any of the settings in inspector have any effect in DX10?

[Jean-Paul 167]

Simple, when I disable Vsync in Nvidia Inspector, I get tearing.
