I guess many of you (who have the CS:S-beta) have seen that theres some new graphics-options, Antialiasing and texture Filtering.

I bet many of you dont know what AA and AF is, other than if you use it, it just lower your FPS that you care so much about :devil:

Well, im not gonna explain how those things works (if anyone wanna do it, just pm it to me and ill put it in the thread), but im gonna show you a couple of pictures so you can see the difference when using AA and AF, and when not using it.

(All pics were taken with my 9800pro, may look different with other cards. I used 1024*768 with everything on High)

----AntiAliasing----

Makes the edges on things smooooth and niice, instead of hard and sawtooth-looking..

-Check the closest wall, the wires, and the antenna, and youll see pretty big differences with and withuot AA.

Some people dont think about those edges, but me and many other graphics-freaks can think they're VERY disturbing :flame:


----(Ansiotropic)Filtering----

Textures, images on 3d-objects making them look good, instead of just being grayscale. With very detailed textures, games can look awsome, but if you want them to look good on distance/from a sharp angle, you should use Ansiotropic Filtering.

In this test i didnt see any difference at all between Trilinear and Bilinear, so i used the same image for them to show how they look.

-You can easily see the quality of the texture on the slope and on the wall next to it gets better the more AF is used.
To see the difference between 8x and 16x, look under the "gate" and you can see a little, not much tho.

----Everything or nothing?----
As you can see on these pictures, its a pretty big difference when using as much eye-candy as possible, or almost none at all.

6x AA and 16x AF
No AA and Bilinear/Trilinear filtering

But do you really have to use as much AA and AF as possible? Well, as you can see the difference between 4x and 6x AA isnt that big, so I use 4x because i want those extra fps that 6x steal othwerwise. And with AF i prefer 8x, because the difference between 8x and 16x isnt that big, but ofcourse its personal, and you should use whatever you like, not what I like :p




If you want me to change anything in this post, maybe if you want me to add more info (wich you have written, im too lazy :p), just send it to me in a PM and I'll add it. Also if something I've written is wrong, please send me a msg and tell me, instead of whine in the thread :)

Excuse my bad english, may have some problems expressing myself because my english isnt that good :p

edit: If there´s any "official" FPS-guide-thread and you want my pics and info in it, just write a msg
 
Cool pictures, you should do some model comparisons. I noticed that the T/CT were mega jaggy without any AA.
 
nice test :)

I'll go for sweet graphics in SP, and turn off the candy in MP
 
Cant afford to im afraid, gonna have to find as many little graphics tweaks as i can, want my css running smooooth :)

r_3dsky 0 seems to give me back about 5-10 fps :)

Also unlocked the 60fps lock and set it too 100
 
Yea, i noticed the most change when I turned on AA is with the player models.
 
What does the 3dsky thing do? Does it turn off the sky or something?
 
These options aren't new

Anti-aliasing and anisotropic filtering aren't new. You can enable them in regular CS too. These are algorithms actually implemented on your video card not by valve. Also, anisotropic filtering doesn't cost too much in terms of fps but AA can easily halve it.

Removes the heads off palm trees and a few chimneys.

No need.

i ment that they havent been in CS before, in 1.5, 1.6 etc you could only change resolution, nothing more (was some months ago i played cs, but you can only change res, right?)

i know that it wasnt valve who "made" these "functions" dooh :p

but many ppl who not know that much about gfx and maybe not have been playing arround with all different settings for your gfxcard maybe didnt know what AA and AF was etc :)
 
Wow, defnitely want to have some AF... I'll turn that on way before AA.

And AA doesn't even seem to have that big of a difference until 4x...
 
You can't take pictures with AA and AF on can you?

Because the process is done by your card and not the game itself.
 
AA 2x really does make a difference while you are playing. It vastly smooths out the guns and models, which isnt evident from the photos.

What do you think the game is running on? ;)

Maybe no one told you but cs is a multiplayer game. just thought id let you know.

I was by no means criticizing your post. In fact I think you did a great job with all the screenshots and what not and it will surely be very helpful for many people to realize the benefits of AA and AF. :) I was simply challenging your statement that those options are new. While they aren't controllable through the game itself in regular half-life or cs you can certainly turn them on in your video card options.

hehe, np ;)
 
OK, I'm confused about the AA/AF, there is a setting in-game for AA and AF, but my Radeon 9600Pro also has an AA/AF setting in its control panel. Which do I set?

I read somewhere that it is better to turn on AA/AF in your vid card control panel rather than in-game. I guess you get better framerates?

Can someone please explain this to me? Thanks!

*EDIT*
God I'm at work and the wait to get home and play is killing me!! This can't be healthy!!!
 
Changing settings in your vid card panel 'forces' the game to use those settings. Otherwise it's just set to 'application dependant' or something. I have no idea what performance difference it would make.
 
Filtering @ 16 is such a performance hit :( but it looks so much better
 
What do you rank the importance of the following:
Resolution
Texture quality
AA
AF

I don't know enough to decide whether to keep resolution up and turn the rest down, or turn down res and put some AA/AF on, or what? I need a balance!
 
if you have high resolution (1280 or more, at least what i think) then you dont really have to think about AF, but AA do you always have to think about ;)
 
I go with 6x aa and 16x af (1024x768). Hurts my framerate a little, but looks pretty. I could possibly get a minutely higher kills/death ratio with a better fps (currently it drops to just below 30 with smoke and a lot of models on screen), but aesthetics matter to me.
