Anisotropic filtering suddenly low - TomFF - 17.05.2010

Hi,

before I describe my prob, my system:
AMD AM3 Athlon II X4 2.8 GHz CPU, 3 Gigs of RAM, Windows XP, Ati HD 5770 1GB GFX.
500GB Western Digital HD and so on..don't know if anything except my GPU is relevant here.

My problem:
In IL-2 1946 HSFX4.11, all of a sudden-no ATI control panel or config ini changes made..The level of anisotropic flickering ingame increased.
I already had set my Ati to the optimal config, worked almost flawless.
Also the config ini settings where okey, activated the "TexMipFilter=3 " for anisotropic filtering.
My IL-2 setup is configured for max graphics quality on all settings.

But from one session to the next, not even entered the game, I see more blurry edges on landscape, gauges, water and sometimes on aircraft models.
Especially the blurring effects on gauges and waterlines/rivers are a bit too strong now.

I've seen the same thing from one flight to the next session in my second install, used by renaming folders.
Second install is IL-2 1946 HSFX 4.1 (not -4.11).

Really no clue, maybe some magic Open GL feature, getting confused with my other sim (FreeFalcon5.5).. Direct X based.

Any tips highly appreciated!!

:newsmile:

Tom

PS: Ati driver 10.4.

Hey, if your game works on perfect settings, then could you post what you made it work, please? I have a 4870 1gb version and unable to play on perfect settings because of Load.ini error allover the place, or having the blocks instead of readable font.

You seem to be describing several things, neither of which sounds like a problem with anisotropic filtering. (plus you mentioned anisotropic flickering once, typo?) Anisotropic filtering is not going to affect gauges, or edges. Its effect on landscape will be seen in how textures remain clear and sharp on surfaces that extend away from you in perspective.

I think we need a screenshot which illustrates what you are talking about. It may well be something else. It almost sounds like you are talking about antialiasing.

I have a similar problem for more than a year. And is most obvious on gauges!! With the advent of 6DoF you can move towards and away from them so they get affected by anisotropic filtering which... apparently does nothing to them... they are simple "resized" by pixel interpolation or so... they get quite a bit of shimmering and they are loosing readability a lot although the textures are 1024 pixels and in full view or close up looks awesome.

Another issue is with the transparency at the canopy frames when looking from external view... once they got "anti aliased" and filtered... now... a lot of edges.

I have a 8800GT video card (4GB RAM, 3GHz C2D, winXP32bit) with all things maxed out in driver (no optimizations or corner cuttings) also the conf.ini lines for OpenGL are maxed up (tried different variants of people around) and nothing.


If anyone is interested in looking at this I could post some pictures.

thats because many ppl forget to redo the alpha mask of the instruments plus if you increase resolution you will get the shimmering effect because you got a texture too large to display at 100% except if youre zoomed in...

Exactly Vpmedia!

Is a problem with new cockpits that look bad from far back cause the game does not make the resize using a re-sampling algorithm rather a simple resize that destroys the texture.

Isn't anything that could be done?

Also the transparency-antialiasing that apparently doesn't work anymore on frames/glass of canopies from external view? This looks like a different problem isn't it?

Sorry for being late, have been pretty busy:
General Psycho, I will get back on this, it was a lot of stuff I had to do before my Ati ran at all...will post that either later today or tomorrow.

All: Sorry, short on time, overflew your (appreciated) responses:

It seems definately to be an anisotropic filtering issue I see, not an AA one. I could be wrong, but I doubt it, especially since the prob is best seen in motion...
Anisotropic flickering means that the moved image, e.g. even cockpit panels (all pits so far), features more flickering on gauge surfaces and gauge texts now.
E.g., the F-86's HUD frame root texture now flickers/shimmers a bit.

Some waterlines flicker or blurr a bit as well-e.g. the Kuban coastline. Hawai looks almost flawless.
No dramatic increase, I have set my AF to 16x(!) and my AA to 8X in my Ati Catalyst settings, just enough distorsion to be recognized and frustrate a bit.

I can also confirm what zaelu wrote..that canopy frames or wing edges-seen from certain field of views now are a bit more blurred.

Another typical example:

The standard Pacific Island map in quick missions:

When I fly low, the shores now are a bit blurred as well.

I do remember how it looked before and I changed exactly ZERO things ingame, in my conf.ini or in my Ati settings.

I may add I saw similar stuff before on my old rig with different sims including IL-2. Literally from one flight to another the next day an increase in flickering.

Sorry for hasty type job here, lot of work ahead today.
Will get back later and certainly try to sum my installation for General Psycho, so that he gets this beast running as well. :lol:


Cheers to all!

Okey, this is an off topic post to help GeneralPSycho...hope to get help with my flickering stuff as well, will post screenies later..

Okey, buddy, did a one hour research to figure how the heck I got my Ati 5770 with 10.4 driver to run more or less flawless in
IL-2 1946 HSFX4.11/4.1 (If you don't know how to install this pack: viewtopic.php?t=25515&start=0)



This forum thread covers all your problems:

http://forums.ubi.com/eve/forums/a/tpc/ ... 088038/p/9


I'll post links for you, but for credit reasons, that's where I got my help:
Crucial posts are the last four posts linked above, page 9.

Start to read from page 7-8!...


Okey: IIRC:
You have several options.
(First, be aware that with current drivers the loadscreen will keep being bugged. But you can fly and after a few seconds or a minute, the corruption in the red text etc. will be gone.
Alternatively, start a track before flying yourself.
In short: Corruptions-yes, but only for a short time.
I disengage all text info in my screen when starting my first mission, so I don't really care.)

To your options:

In the IL-2 forum linked above, I downloaded 2 files:

"atioglxx", to place in your IL-2 1946 root folder. It is a file from an older Ati driver to enable proper gameplay with newer drivers.

http://www.mediafire.com/?anwzyzhwvte

NOT MY LINK, credit to the guy in the IL-2 forum!!

I did not use this file IIRC. Tried once IIRC..It caused problems in my install.




Instead I read a little further to the bottom of page 9 (see above link) and made the changes

S!
At a glance I can see you are missing one option under [Render_OpenGL] that causes this. Change the following line: TexFlags.TexEnvCombineExt=0 to 1 and the black scenery is gone. Those 3 choices there, one above and below this choice are imperative to be kept at 1.

Also you can try to set the following lines to 1 as well:

TexMipFilter=2 to 3 (enables Anisotropic Filtering]-the only thing I had to change..
TexFlags.TexEnvCombineDot3=0 to 1
TexFlags.SeparateSpecular=0 to 1

Otherwise your setups looks OK. I hope this helped.

S!

Orville. This anomaly you have is due the DLL-files that are in IL-2. Called il2_core.dll and il2_core4.dll. Best ones for me are the ones dated 13.3.2008, but you get rid of those artifacts also by enabling Catalyst AI at Standard setting. Linky to the IL2 dll-files below, just make a backup of your existing ones and drop the new ones in IL-2 folder Smile Linky: http://www.mediafire.com/?nmtmmjxnymz

I downloaded THAT filepack, it really helped!!!!!!

http://www.mediafire.com/?nmtmmjxnymz


In it included are 5 variations of those 2 files. I chose the ones closest to the date Flanker posted. (Huge thanks to this man!!)


They worked!.


So, IIRC, I did 3 things:

1 Download the above linked "5_DLLS" filepack, took 2 files from it and inserted them in my IL-2 1946 main install.
Always backup files before replacement!!!!!!

2 Made the conf.ini changes reported (quoted) above for anisotropic filtering.
TexMipFilter=2 to 3

3 And this, also found (quoted) in the IL-2 forum IIRC:
"
A small tidbit picked from 1C forums from ATI thread Smile To get Vertex Arrays working without the annoying "blue hue" do the following: disable Dynamical Lights in conf.ini under OpenGL. Set from 1 to 0 and save. Does the trick."


That last trick cured blue shimmering when guns are utilized etc.


That should get you started.

If in doubt read the link posted first. All infos in there.
Disregard last more negative comments.


And yes, frustrating to have a brandnew rig and do a huuuge dance to figure out how to get this sim running on forkin new Ati drivers.

TomFF, check your PM. You did it. I am glad that you have spent time and found the issue unlike some others.....

This sim is truly epic..



(Will post later screenies about my prob in case anyone knows a clue.)

Standby, help dudes.. :wink:

- TomFF - 19.05.2010

I collected some screenies and typed text in them lol to attempt to illustrate my flickering AF/whatever problem:

That is a shot from before the above described problem occured (blurred effects on coastlines, some aircraft textures and gauges/pit structure):

The text referrs to a new area which now is blurred in motion:


Shots WITH the prob:
Here..


Here:


Moreover here:


What's new: Coastline flickering/blurred/..



Help appreciated, this is my favourite sim with FF5..
:wink:


Thanks a lot guys! Sorry for being a pita here. :lol:

I'm not seeing it, sorry...maybe it is only evident when things are moving?

Shimmering, jagged, coastlines has always been a problem with the sim, because coastlines don't get antialiased, but since I'm not exactly sure what I'm supposed to see in these screenshots, I'm probably completely off base.

I'm just going to sit back and hope to learn something from others on this one.

Hehe!! :lol:

Yes, what I see, and, as stated above, without any edits from my side in either Ati Catalyst or conf.ini settings etc is this:
More blurry effects now on coastlines, in my cockpits and in general on all transition textures/views including wing's edges in some views.

Yes-these effects are occuring in motion thus hard to describe via a screeny..

Anyway, all tips appreciated, have to work now but will surely check this thread later this day (German "Kraut"-time .. :lol

No idea? Anyone? :lol:

By now I set my ingame resolution a bit higher, my GFX now shows up to 60/65 degrees Celsious..haha.
But it looks better. Hope my Ati doesn't smoke off..-

Still wondering. :wink:
