Does anybody know if Temporal AA works with LCD screens?

i heard its based off of refresh rate, and since LCDs dont have that exactly i was wondering if it can still "trick the eye" or whatever its doing. Also, ATI Tray Tools has an option for 3x and i was wondering if that would make a difference using an LCD at 60hz. Thanks!

Yes it doens't matter what kind of screen you have.

Adaptive AA (or Transparent AA for us Nvidia people) simply applies either multisample AA or supersampleAA to Alpha Textures. It means all those plants in FarCry will now look better.

Now I think that ATI only uses Supersampling but I could be wrong. Multisample AAA (TRMS) doesn't work to well in some games, and in some games it really doesn't work at all (HL2). Thats why I always have it on TRSS (Quality AAA??? 3xAAA??? I have no idea what the equivilent ATI setting is, so just max it out).

Not totally answering your question (since I'm not sure on some things with ATI) but it's better then nothing :p

Actually, you totally missed the question :p

It's not aboot Adaptive/Transparent but Temporal which produces the visual effect of higher levels of traditional AA sans the performance demand.

Yes, Temporal works with LCDs with the usual caveat that it requires and thus forces Vsync and so if the frame rate cannot be maintained at 60Hz then FPS will dip drastically. Triple Buffering may preclude that at the cost of increased VRAM useage which in turn could cause spill-over into slower system RAM.

Whether the Temporal multiplier makes a significant difference in IQ is more dependent upon the resolution and initial AA level.

Whoops. :eek:

lol, Sry about that.

On my older ATI rig I normally didn't have it one since I never really saw the differnce bewteen 4xAA and 4x w/Temporal AA.

You have nothing to lose, except some performance. If it slows stuff down too much, then turn it off.

EDIT: Oh BTW, your computer rocks! But surely you could squeeze a few more MHz out of that 4400+ ;)

Depends upon a given game and other settings whether it is worth enabling. If Vsync is preferred anyway then prolly but otherwise no. In any case, using ATT such options should be enabled on a per-game basis via profiles rather than globally. As you know from 'nutha thread some games' internal settings require default driver settings.

i tried getting more out of my cpu...but to no avail. DFI is a great company, but it just gets too hot on air to go more than 2.66.
