I love almost everything about DX10, especially the elimination of graphical spikes that I used to see with BP=0 on DX9. However one challenge remains, shimmering of ground objects and in particular winter trees (branches without leaves have lots of transparency inbetween) and airports in the distance.

 

To get near to the level of quality I had with DX9, the following configuration is necessary:

 

 

MultiSamplesPerPixel=8

MultiSampleQuality=8

8xSGSS

 

Of course, it's not long before this is a frame rate killer whenever significant clouds are involved.

 

So my question is, is there some other way to do this or should I really be lowering my expectations of image quality a little for DX10?

That's the one that does the most at this moment, Simon. Of course there are various "extra" settings one can try and add to those three, such 4xS, or FXAA, and the addons like SweetFX, but SGSS is the only thing (that I know of), which stops shimmer - (and my Profiles folder is littered with them).

I was plagued with 'shimmers' (I think!) switching on FXAA via NI fixed it pretty well. I did not notice any reduction in performance and the aircraft preview image was also a lot better.

Would you mind sharing your Nvidia Inspector settings please? I'm not sure if I have it working or not.

 

Simon

Darn. I switched on FXAA for some on-line flying this afternoon, and there was lots of shimmering, so i'll put it back to just the plain 8xSGSAA and see what happens in the same area.

Select the MS Flight Simulator X profile and set Nvidia Predefined FXAA Usage to Allowed and

set Toggle FXAA on or off to On. Don't bother setting the FXAA indicator On - it just puts a green square in the top left hand corner of the display to show FXAA is On

 

It should look like the attached screenshot

Thank you everyone for the help. After many trials I found the following to be a good combination:

 

MultiSamplesPerPixel=4

MultiSampleQuality=8

4xSGSS

(No FXAA)

(No SweetFX)

 

It's not DX9 image quality (at 2xSGSS), but I think it's something I can live with. Flying in low visibility or in summer also helps! Sometimes that's working my graphics cards pretty hard, we'll have to see if there are any cloud combinations that kill it. But for now all is good, at last I can do some "proper" flying in DX10.

I use these settings for DX10 preview:

fsx.cfg:

MultiSamplesPerPixel=4 // using 8 is a huge perfomance killer for a very small improvement

MultiSampleQuality=16 // this enables nvidia 16x AA

NI:

4xSGSS

 

It looks that all other settings in NI, other than FXAA, are ignored. I too any am an IQ freak and spent lots to time to end up where you also ended up. I've found these settings to be so close to what I had in DX9 that I've now forgotten what I had in DX9 (though this is what I'd be sorely missing if I went back to DX9: environment bloom, VC shadows and bloom, much better looking water and overall better visuals and performance). To see the IQ I get, check out these DX10 screen shot I made:http://forum.avsim.n...s/#entry2569390. Fortunately I don't use any add-ons which suffer major DX10 compatibilities issues (but I do sometimes miss using UTX street lights at night). Enjoy!

Thanks Rod - I will try this one today. I never thought to move the MSQ up to 16 in the cfg.

Thanks from me too. I gave it a try, and while it looks great when the simulator is paused as soon as we are on the move the shimmers are still there and still slightly worse than those I see in DX9. So I guess it's a trade off, loose a little in image quality to gain all the DX10 features you describe (at least it's that way on my PC).

What shimmering do you still find bothersome? I find that airfield stripes shimmer the worse, as do straight edges in the VC though only by tiny amounts (essentially I have to stare to find them). Autogen trees look fine on my system. 8xGSAA will help with the trees if necessary, though it comes with a performance hit. Recently I ran a DX9 test to compare these shimmers and found that DX9 AA wasn't perfect using NI 8xS + 2xGSAA (it was only marginally better at best; higher DX9 AA settings choked my performance to unacceptable levels).

May I inquire as to where in FSX.Cfg you place the multisample lines ? Under [Display] maybe ?

 

Thanks,

jime

Hi Jime - yup - under [Display] You can play with the numbers, though I never tried 16.

Thank you very much, gentlemen.
