Antialaising and Anisotropic Filtering

[Valo]

How I can setup the AA and AF? I've searched all the Options Menu, but didn't found it :shrug: This is a picture from DK forum, Kei post it :thumb: , but don't know how he do it :scratchch

Usually you set your AA and AF in your Graphics Card's options in Windows. LFS does not have such options in its menus. Open up your Display Properties and goto your your Advanced settings for your graphics card. If you have a graphics card that is capable of doing this, and you have proper drivers installed, then it shouldn't be a problem. However it can lower your performance if your system is not that great.

By the way, what kind of graphics card do you have???

[Vykos69]

Valo, you have to set Antialiasing and Anisotropic Filtering in the menu of the driver of your graphics card. NOT in the game.

I'm with NV GeForce FX 5600XT
10q for the quick reply, I've found it and will try it, if it lags too much can I turn it off again, I mean it won't be a problem to return the old settings?

[Tweaker]

Those settings are purely just to make the game look crisper and nicer. Most people don't run with the settings enabled, because they want the most FPS out of their game. But if you are taking screenshots or something, you would want to have those options turned on high so you can have a really nice picture :)

When I turn on AA (4x) nothing changes in game. Still very aliased edges. Even if I setup a profile in the Forceware driver and point it to LFS I get no AA in game. Anyone know why?

I've even tried here at work where I have a lesser GeForce card but still no AA.

I have to say, alothough I only use 4xAA and 8xAF, I cant find 1 PIXEL difference between that and the look of mine .... was it really the 8xaa and 16xaf?
btw its x800xl

[Peptis]

Some other people (myself included) are having the same problem. There is another thread here:

http://www.lfsforum.net/showthread.php?t=8983

However, it doesn't seem to offer any solutions.

I have tried re-installing my ATI Catalyst drivers, but no luck. Waiting on the v6.6 drivers to become final (only beta at the moment) so that I can check them out.

[S14 DRIFT]

I would suggest making sure you set up your AA/AF BEFORE!!!! (yes r0x0rz BEFORE) you start up LFS.
If that dont work (and I cant imaging why not) try redownloading your gfx card drivers, putting the install file on your desktop, unistall your drivers, and restrat and install the new one!!! :D

I would have thought that was quite obvious.

Anyway, I have tried a full uninstall, followed it up with a run of DriverCleaner, and then istalled the newest drivers. Outcome: Nothing.

[SladiVadi]

Ati Tray Tools might help.

[SamH]

I don't know if this helps, but I can change most gfx card settings while running the game, but the effects are not enabled until I Shift+F4 into full-screen mode. When in windowed mode, the nVidia options don't come into force. If I change card settings, and switch via Shift+F4, they're set.

While on the subject, no matter what I do (or sequence), I can't turn off AF. I'm stuck with green dust/smoke. I've reinstalled nVidia drivers, downgraded, upgraded.. you name it.. can't shake AF. Suggestions?

Sorry if this is a thread hijack. Seemed like a good time to mention it, with people already on the topic.

^ make sure you are using a 32bit screen mode..


Also for Nvidia card make sure to lock the LOD to "clamp" and use "high quality" for the "image settings" in the profiles.

LFS engine is so optimized you can still use pretty high levels of AA and AF and get very fast FPS.

not really! its just that the CPU is always the limiting factor in the equation, and the gfx card is sitting there being held back, so if the card if decent, high levels of AA and AF wont change the speed much :):thumb:

To re-iterate;

Anti-aliasing, and Anisotropic does not work in 16 bit mode.

(well it didn't for me 12 months ago till I figured it out). To run LFS in 32 bit mode, just go to options, then under "Screen", make sure you're running a resolution at 32 bits. Problem solv-ed :)

[george_tsiros]

this is a weak argument.This is a stronger argument!

Antialiasing and anisotropic filtering work for my 6800 pretty well at 16bit. i can take screenies if you want...

[Takumi_Project.d]

correct, 16 or 32 bit shouldnt matter, AA & AF works in both :)

[george_tsiros]

here are 5 screenshots.

none: 16 bit, both antialiasing and anisotropic filtering off
antialiasing: 16b, antialiasing at 8x, aniso off.
anisotropic: 16b, antialiasing off, aniso 16x.
both: 16b, antialiasing 8x, aniso 16x.
both_32bit: 32bit, antialiasing 8x, aniso 16x.

[george_tsiros]

Also for Nvidia card make sure to lock the LOD to "clamp"

I'd say "allow", because LOD values which are below 0 give better detail.

If you "clamp" it at the driver setting, it will override the setting in LFS.

[BWX232]

16bit was referring to the post above and green smoke -hence the "^"...

Takumi_Project.d, yeah really- it is very optimized.

I was going to give the "CPU dependent" speech but figured too many people would start arguing about it and I didn't feel like taking the time to prove them wrong so I left it out. :shrug:

- and make the entire screen look like crap.

It makes the entire game have horrible texture aliasing. Not something seen in meaningless screenshots either... but some of it can be.

What you describe and ask does not make sense. Here you can find a description of anisotropic filtering (http://en.wikipedia.org/wiki/Anisotropic_filtering), in case you've missed it by now. I can not imagine what green smoke has to do with it, but when you spin wheels while on grass, the smoke is green. Can you describe with more detail?

Here is a screenshot how you can disable the anisotropic filtering from nvidia settings... If this doesn't work, something is seriously borked with your drivers :schwitz:

Dude, no need to cuss... chill... i run the game at 1280x1024 (normaly) with 8x antialiasing. i have the bias at -4 and it looks sweet. If you use lower resolution without antialiasing, it will look strongly aliased.

I did not say that it is better to use LOD<0. Just that it gives better detail because that's what it does. LOD = Level Of Detail.

EDIT: It is the MIP BIAS that i am talking about here! i just noticed that only MIP BIAS works this way (lower value = better detail)... USER LOD works in reverse (higher value = better detail). i made this mistake, but the "negative lod bias" setting in the driver settings DOES affect "MIP BIAS" in LFS.

cuss? Who cussed? :really:

I run 1600 x 1200 4xAA (supersampling transparency AA), 16xAF, etc, etc..
I know how the settings work.. my experience has been that using that setting mentioned above eliminates the texture aliasing that happens when using an Nvidia card. I had an ATI before and that never was an issue.


In general ATI has better overall IQ... you just have to make sure to set up the driver control panel profile settings for LFS to get the best IQ out of an Nvidia card. I have a 7900GTX, going from an X800XL, and the Nvidia card in LFS doesn't have nearly as good image quality with default driver settings.

I'm away from home at the moment, on a laptop, so I can't create a screenshot. What I'm talking about is a greenish tint to the smoke. Not the green of the grass cuttings.. this happens on tarmac. It's a FPS-killer for me. I know it doesn't make sense, and that it shouldn't happen. That's the point of posting, really.. it's a glitch somewhere which prevents me from turning of AF. I'll post screenies of my nVidia settings, and a screenshot in-game of the problem occurring when I get home this evening :)

Could be the 'whitepoint ' settings of your monitor calibration? I was getting brown tints to some dark road textures till I calibrated it better now they look black, perhaps the green is a result of this?

What color-depth are you using? 16 or 32 bit?
If it's at 16-bit try turning "dither" on. If you're using 32 bit turn it off. That's what worked for me anyway ;)

[george_tsiros]

eliminates the texture aliasing
Yeah, but that way brings clarity down. The solution is to apply lots of AA.

we misunderstood each other,i am glad we sorted it out. your explanation helped me understand what exactly you were talking about.

[SamH]

Hi guys..
Attached are 4 screenshots. One is my nVidia display settings, and the others are screenshots from in-game.

The screenshot with "paused" in the middle is with the LFS window maximised but not fullscreen. The screenshot WITHOUT the pause message is when I switch to fullscreen.

You should be able to see that the quality of the dust is poor and ragged in the fullscreen image. Am I barking up the wrong tree, and this is a different setting?

The last image is a montage showing my LFS graphic settings. I admit, I kinda follow my nose in these settings because I don't fully understand the options :shy: but with the difference being between windowed and fullscreen modes, it seems to me that the culprit is hiding in the nVidia settings. (image quality settings don't make any difference btw).

Any and all suggestions/recommendations VERY welcome!

If anyone

You are using 16bit as I thought- set it to 32bit.

Use some anisotropic in your video card setup too.. at least 4x.

You have it set on hight performance, it is going to look like crap. Set it to quality or high quality.

[SamH]

Brilliant! Thanks very much! I'd forgotten about the "show 32-bit modes" option. Clicked that, and the 32-bit modes were available. The smoke/dust quality was fixed instantly!

I remember now that I selected 16-bit colour originally because for some reason I can't record in Fraps in 32-bit mode, because the framerate drops off to between 4 and 6 fps. I have 2 installs now, one of which I'll run in 16-bit just for recording.

Thanks again! :)

[BWX232]

Cool, glad it worked.
