Hey, i was stuffing around in my registry when i came across a thing in device0 in hkey local machine, and it let me set the threshold of Temporall AA while using the newest catalysts, and then i found something that let me change the amount of AA patterns in temporal AA.

heres my guide:


Ever since having 18xAA using 6x T3 on the omega drivers, i wondered what it would be like to have hundreds of AA samples... After reading someones CSS tweaking guide and following the link about V-synch, i learned how to change the temporal threshold on the catalyst drivers without having omega drivers. So i opened up regedit, and i created the string line and entered the value of 0, so that i will have temporal on, no matter what my fps, and no matter how low my fps drops. after stuffing around for awhile, i found another thing in the registry, on the same page. It was labeled TemporalAAMulitplier. I opened it up, and it had the value of 2. that means that my AA samples are switching between 2 different AA samples. I quickly changed that from 2, to 15, and i set my normal AA to 2x, and enabled temporal. i booted up hl2, and sure enough, there was no fps drop on my PC, but instead of having 2x AA, i had 15 AA samples, at the price of 2x. Then i told myself, (you can guess).... 1000000000000 million AA, here we come!

i opened up regedit, and i changed the string value caleld TemporalAAMultiplier from 15, to (you can guess) 50000000000, and i booted up hl2.

SHWEET!

god knows how many AA samples i had on the screen. Beutiful i tell you.

Im not responsible if u stuff up ur PC, so back up ur registry before you do anything. If you dont know what you are doing, dont do this.

To change the threshold to 0,

Start -> Run -> regedit



now, if u have an ati gfx card, go to:
HK Local Machine\System\ControlSet001\Services\ati2mtag\Dev ice0



if u have an Nvidia card, go to:
HK Local Machine\System\ControlSet001\Services\nv\Device0


To change the threshold, add a string value:
name it: TemporalAAFrameThreshold

double left click on the string value you just made, and type 0 and hit enter.

To change the multiplier:

theres a string value called "TemporalAAMultiplier"

it wont be there if u have an nvidia card, so you have to create it. its a string value.

if u have an ati card, it will be there.

double left click on that, and put in whatever number you want.... Default is 2. put in something like 15 to try this if u dont beleive me. if u want, you can put in anything.... just make sure u dont go

99999999999999999999999999999999999999999999999999 9999999999999999999999
99999999999999999999999999999999999999999999999999 9999999999999999999999
99999999999999999999999999999999999999999999999999 9999999999999999999999

or something... i reckon you should be able to go that high, but its really up to you. currently, i have it set to 50000000.


After changing the threshold and the multiplier, go and set 2x AA from the ATI control panel, (or the NVIDIA one).

try playing hl2 now.


Sweet huh?

oh, and btw, dont flame me because i am a nub.

Are you sure it worked? 'Cause if you could have "256xAA" why shouldn't ATi integrate an option to choose the multiplier used? The bad thing is: you can't take a screenshot of your experiment ... because the effect of TAA isn't visible on screenshots.

Ive emailed ATI's catalyst maker, Terri

TJ-

has anyone else done this..? is sounds dodgy...

Sounds f*cked up bro... but should I try it?

ive got a few people to try it and they say it works so much better than the standard AA, but if u wanna try it, its up to you. ive emailed Catalyst maker about it.

if you want my original thread, PM me.

tek

So this doesnt affect FPS at all but just adds more AA samples *makes shiznit look smooth*

basically, it makes 2xAA look like ownage.

TJ-

hey tek man if you try it post your results, im not really inclined to trust this method from a guy with 2 posts... i still think its to good to be true

I'll give it a shot tomorrow

Duranix: So you MUST have at least 2xAA enabled?

yep.

you can do 2x - 6x, up to you.

pr0digal jenius

screenshots don't work....but fraps videos do

someone try it and post a short like, 5 second video

Duranix

ill post a video, but to use fraps, i need to do the video in low quality or the video will have somewhere around 3 fps.

where can i upload to?

CrapolaJola

This is just temporal AA thats all it is and there's limits to it as well the max is 18x or 20 soemthign x AA, it does not go up to 100 and ur crazy numbers man.

theres a limit?

oh well, atleast it makes my screen look like 20xAA at the cost of 2xAA.

id rather have this than have standard 6xAA

Judas

hmmm..... i'm not completely understanding of how the temp AA works... but if it works like this:

2x AA provides a solid 2 samples per frame.... were as 2x TAA provides what we would consider 4x AA because it does 2 samples per frame, but every other frame has different points that are sampled, with our eyes excepting the differences as a blended 4x AA final.

Now i can see it being possible to couple a large amount of multiple AA frames into a batch that could simulate a very very very large number of AA.... but if your FPS hit anywere below a specific number, it would appear more and more like normal "2xAA".

Lets say we take an even number divisable by 2. say 100 fps, as we don't want to be really out of our range and say "200"

so we have 100fps. we could theoretically, shove 2xAA into each frame that is different, In one second, we could theoretically see it at "200xAA". (remember, just saying theoretically)

now the eye i'm SURE is going to notice something within 1 second, so lets say that in 1/4 of a second, and lower, our eyes would NEVER tell the difference due to the ammount of visual information we are seeing all the time, blending it alltogether automatically. I Personally could see this being possibly a 50xAA sampling technic. Got a game running over 200fps? that's 50 frames in 1/4 of a second. which could be seen as 100xAA for each frame having a different 2xAA sampling.

Moved to the ATI Radeon Display Driver forum, i'm sure this MAY interest a few people.

biggest BS i've ever heard

TAA multiplier limit is 3 and btw it is there for good reasons

thats why i disabled the threshold... that way, no matter your FPS, you will still have temporal on. i see your point though..

still, ive had people try this out, and they get around 35 - 60 fps a second, and theyve all reported that it works really well with no, visible problems. im still waiting for catalyst maker to email me back...

ive been testing this thing out, and it works really well for me.. i get what looks like 6xAA on hl2, but theres basically no performance drop on my 9800 pro.

Pierro

there is a limit to the TAA multiplier

if you see any difference, it's most likely psychological

yeah... it probably is... but still... someone test this out.

Spyre

Its total BS you cant go above 3

Use this util if you want a quick way to see what Temporal AA does

I agree with Judas. Too high values can't make much sence, as the card can't produce the frames quickly enough for them to blend, but there's a number of games where one could probably get 6-12X effect, which is pretty good. I'll try and see.

Spyre

More proof that this is BS is that Nvidia cards cant do temporal AA as their sample patterns arent changable on the fly without doing two pixel passes which would kill any benefit of doing Nvidias supposed temporal AA in the first place

well, ive had people using 6800 GTs and they say it works.

griswoold

In their wet dreams maybe

Nvidia card's cat use TAA thats bs. Also don't get rid of the threshold, at lower FPS you'll start to notice flickering on a lot of things with TAA. Thats the oen reason why TAA hasn't replaced AA at low speeds it flickers where as reg AA still looks good.

i thought so too, but my friends proved me otherwise...

IvanV

Don't be so stubborn. There's no Temporal AA on nVidia's cards and creating a reg. key like the one for ATi's cards wouldn't do anything. The effect your friends might believe in is purely psychological. I'm becoming more and more sceptical about the whole thing...

germanjulian

what is the point of 100AA? over 12x you wont see any difference propably anyway.

best AA i have seen...... turns head 90 degrees to his right away from screen and looks outside window.... great effect.....

eh, you dont have to beleive me if u dont want to.

on hl2, it looks like 6xAA, but the performance drop is like 2xAA. it runs better and looks better. How will u guys know unless u test it?
