Anyone tried Temporal AA yet?

I've been using it for a couple days now:

It works really, really well on a slow-refresh LCD. The pixels don't seem to have enough time to fully discharge/charge back up and the LCD seems to smooth it out quite nicely even at 60hz.

On high quality CRT's there is a slight shimmering effect, its just noticable at 60 hz to me. I try to play games at 85Hz, and there definitely seems to be a noticable difference setting TemporalAAFrameThreshold to 42, and 43. At 42, its definitely noticable, at 43 it shimmers but looks passable (a little less noticable than a badly shielded monitor cable and the associated swim)

There is also the tiniest bit of lag in the transition threshold, its like one frame is taking longer to display.

It looks perfect to me if I set the threshold to 85, but only about half of the time does my framerate ever hit the cap.
 
Would be nice if there was a utility that would turn this on and off....I got an idea..maybe ATI could make it and they could make it part of the control panel!! </end sarcasim>

Seriously, is there a utility to turn this on and off and change the settings?
 
i tried to enable it but for some reason couldnt get it to work....i must have been doing something wrong...
 
I did enable it on my 9800 Pro and it seemed to work okay (used America's Army), although you need a decent monitor (for V-Sync refresh rate, the higher the better although 85 Hz at a given resolution seems satisfactory, IMHO) and framerate (>60 FPS minimum, preferably) to fully enjoy it. I feel that TAA will become a subjective matter, since people already debate about being able to discern refresh rates and FPS, although TAA tends to be more noticeable in some cases. I personally think it's a good concept, since a good deal of optimizations and techniques with graphics already fool your eyes into seeing an improved image. Receiving better AA/IQ at little performance cost (TAA requires V-Sync, which imposes a performance hit, although I always use it anyway) is fine with me.
 
ahh, the joys of owning an LCD screen.....no flicker whatsoever :D

and i am highly sensitive to flicker, especially ever since i got my LCD....but even before then, anything less than 70hz hurt my eyes....

of course, i have an nVidia card, so no TAA for me (at least not yet...i may switch to ATI later, if i can afford to upgrade anytime soon... )
 
Refresh rate, cost, and viewing angle are the three things that drive me away from LCDs...although it would be nice to have one. I imagine flickering with TAA might be a bigger issue on LCDs, though...for various reasons.

As for going ATi, one of the best choices I ever made. I loved my GeF3 and even my GeF4, but the 9700 Pro raged and I was disappointed by the initial FX cards. This 9800 Pro has served me incredibly well over 14 months, and I will be sad to see it go after 15 when I pick up my X800. I don't mean to show bias by that statement, I may very well buy nVidia again, but for this round...ATi is the ideal choice for my configuration.
 
according to ZenOps in the initial post in this thread, he said that the LCD smoothed out the flicker quite nicely, which is what you would expect....there's a night and day difference between 60hz refresh rate on an LCD and 60hz refresh on a CRT. i usually run my LCD at 60hz, and have never noticed any flicker whatsoever, but i'd have to see it in person in regards to TAA to really know for sure if it would be better or not.

probably the main thing that has kept me away from ATI for so long is the horror stories i've read about ATI drivers, and the fact that even the last ATI card that i owned (AIW 8500DV) was absolute shit for gaming. my GeForce2 MX 400 would run Dark Age of Camelot at 1024x768 with no problem, while i could not even get the ATI card to run it at all..... the whole screen would jump and scroll every time i would load the game.

i know that the ATI drivers are reportedly a lot better than they were in the 8500DV's lifetime, but i've stil seen plenty of reports of people having to try driver after driver after driver before they can get the damn things to work properly. that's something that does not really appeal to me at all...i don't like screwing around with different drivers just to get my damn screen to work properly.

to this day, every nVidia card i have owned (GeForce2 MX 400, GeForce2 GTS Pro, GeForce4 MX 440, and GeForceFX 5900 Ultra) have all installed and ran perfectly without a hitch. even when i upgraded, i didn't even have to change anything, i just pulled the old card out, put the new card in, let windows detect the new card, it used the same drivers, and all i had to do was reset my resolution and refresh rate.

i don't want this to turn into an ATI vs. nVidia issue, i'm just stating my personal experiences with ATI & nVidia, and the reasons i have (so far) stuck by nVidia.
 
oh yeah, i will admit the LCD does cost quite a bit more, and does have less of a viewing angle, but i am usually the only one looking at the monitor anyway, and it's always from the optimal viewing angle, so it's a non-issue for me.

as far as the price, yeah, my 18.1" LCD was $700 at the time that i bought it, but it has been worth every penny so far, and hopefully will be for a long time to come. not to mention, it takes up WAY less space on my desk, and produces a whole lot less heat...and is easier to transport when needed.
 
go lcds!! i use temporial aa with mi lcd at 60hz (thats the fastest it goes, cauz its a cheep 15 inch one lol, but i'm thinkin bout gettin a bettar one) There is no flickering wat-so-ever. I think its the best monitor i ever owned, because on some crts (i made mistake), there is flickering when its under a certain refresh rate, that mi video card would probably not produce in many high end games... so if u have a lcd i recommend temporal aa because there is no performance impact, and most people with lcds run vsync

Anything less than 85Hz drives me nuts and will give me a headache in just a couple hours.

Refresh rate with LCD's doesn't matter since LCDs don't refresh like a traditional CRT. You are probably noticing pixel response time which is probably high with a bargain LCD, but setting refresh rate is not going to change anything.
 
i made mistake, i corrected it, but actually mi lcd isn't that cheep (its $400 for 15") and its pretti good, a sony with bout 25ms pixel response time...
 
i'm not sure what the pixel response time is on my Mitsubishi Diamondpoint NX85, but it's gotta be pretty low, cause i never notice any "ghosting" that a lot of LCD's are known for....this is by far the best monitor i have ever owned, and i'll probably never go back to a CRT

and reading text on this monitor is WAYYYY better than i have ever seen on most any other monitor...it's just so crisp and clear
 
Does Temporal Antialiasing work with lesser Radeon cards, e.g. 9600/9700?

Which card would be needed to run at 800x600 with 4xAA or 6xAA at 60 fps?

It requires a 9500 or higher
