Discovered fix for dx10 + sfx SMAA disable problem

Recommended Posts

Hey guys,

 

Not long ago, I posted here about this issue and recommended not to use sfx w/dx10. For those who might not remember, I said that when using dx10 mode + sfx, there's a problem where SMAA must be turned On or it darkens the whole scene, making your sim unusable. The major annoyance was that you either had to turn off sweetfx completely or stick to SMAA, which although allowing properly lit scene, overrides the perfect dx10 aa settings (causing jaggies) & increasing the load on the gpu.

 

GOOD NEWS! I found the fix!

 

At first, I was pretty sure this is a bug within sfx, and sfx's author CJ looked at me weird when I complained about it. So, here's the fix: upon installing sfx and it's cfg app. Turn OFF all features and leave ON only 'LIFT GAMMA GAIN'.

 

Throw in the following values:

 

1.1 / 1.1 / 1.1

1.5 / 1.5 / 1.5

1.5 / 1.5 / 1.5

 

Once you put these in, the scene will become properly lit again, and hurray! you have perfect AA and perfectly fine working sfx, without performance loss! Play around with the values until satisfied. Each row must have the same R/G/B values or a certain color might oversaturate the scene.

 

Suggested sfx features to play with:

 

1. LUMA SHARPEN

2. TECHNICOLOR
 

Also remember that you can create different presets. :)
 

That's all you need really... I suggest following the term 'KISS' - Keep It Simple, Stupid.

Well done, Ari! That's a real positive piece of good news!

 

Thank You!

 

All the Best,

Adjust the settings. These are arbitrary values to get you started. I'll post a more refined set of values later.

I must say these suggestion is good flying at night and not during the day, it will be too bright.

 

The point Anthony - is that Adi has made it possible for everyone to start this version of SweetFX for the first time, without it immediately plunging the FSX into darkness.

 

This has been the most disconcerting problem for someone who has never played with SweetFX before, and most often results in them not bothering with it, or rolling back to the earlier releases - which is what I did. It's a great find, and is the result of some dedicated research.

Ok, here's a realistic set of values:

 

1.0 / 2.25 / 1.15

 

Input each, three times per row, from top to bottom.

 

I used 12:00 daylight as reference and toggled sfx on/off to compare with stock fsx.

New for REX4:

1.0 / 2.25 / 1.08
I also discovered this fix is needed on p3d2 as well:

1.0 / 2.25 / 1.15
More testing to be done, 1.15 might get lower to 1.08, not confirmed yet.

 

And an important note regarding usage of SFX:

 

I see many people claiming rex textures don't display in-game like they would in preview shots. Here's why: when you're changing the scene colors via sfx, say by using contrast modifications, you're creating a major difference to the textures! every small change in the values counts! using the values above, you should get near no modification to the original texture colors. I'm also working on fine tuning the values further. Stay tuned & enjoy! :)

Adi, can I just confirm you're using SFX version 1.5.1. I've just installed it and used the following settings (1.0 / 2.25 / 1.15) but get a green screen?

 

I only have LIFTGAMMAGAIN set in the config settings?

 

Any ideas.

Yes, I'm using 1.5.1.

 

You probably input the values incorrectly. It should be like this:

 

1.0 / 1.0 / 1.0
2.25 / 2.25 / 2.25
1.08 / 1.08 / 1.08

Ah Ha...That's what the problem was. I just copied the lines like this 1.0 /2.25/1/08 and did that three times...Wow, what a difference.

Thanks Again Adi.

Well mate, bravo, well done! Really really good discovery. At least the text on cockpit displays is now readable without SMAA, nice.

 

Cheers!

Exactly! This fix is crucial to get rid of the useless SMAA. The SMAA doesn't make it near as clear as SGSS x4 or higher. It's an 'edges' only algorithm AA. Useless for FSX. The problem wasn't as obvious in dx9, but it was there as well.

Great Adi, been having the same issue with SFX 1.5.1 dark screen and after searching the SFX presets site checking all 1.5.1 presets with smaa unchecked saw that the LIFT-GAMMA-GAIN settings were alted so tried a few and dark screen gone, mucked around a bit myself but just couldn't quite get it right so have just tried your adjustments and I thank you using them along with shade and DX10 AA back to sharp with great graphics and colours.

 

Cheers Rod.

Not work for me:( Maybe ATI can't disappear jaggies. I think DX10 needs bigger guns and i mean a powerful gpu.

6850 is kinda weak, yes. Especially if you want SGSS for the gauges to appear nice. It requires a powerful GPU like 7870, 7950 etc' or 660/660ti/670 etc'. The higher the better.

A good read are a couple of threads here and here, Jewel77, where Michael Moe describes his journey from an ATI gpu to an Nvidia 780. Adi has it moderately right when he quotes the 660/660ti/670, etc.,  - my own feeling is the 7xx series, and preferrably the 780, if you want to see FSX at it's best.

As Adi says, though - the higher, the better!  :lol:

Thanks adi, will give these a try, haven't used SFX much lately because of the SMAA settings making FSX not look so good.  I like how crisp your screenshot looks above, very nice!

 

You are right peejm the 780 has made simming quite enjoyable.  Tonight I discovered how well my 40" LED looked when I switched the display's "Game Mode" off, there isn't any lag whatsoever and the textures look so much more life-like.

Hello Adi - merry christmas and a big thank you for your hard work!

 

With your findings, I now see myself coming back to nightflying in DX10. Im no savy when it comes to sfx, and I havent had much luck with google, so please: How can I, using your settings as a base, make my nights more dark, eg. the water darker and the land textures darker at night? Will doing so ruin the AA...?

 

Thx again,

 

Mas

You can try adjusting the mid-tones, but it will have a global effect, meaning daylight will be affected too. It won't ruin the AA.
