Temporal AA Frame Threshold

[Bubu123]

Dnes bol nudny den tak som sa kus hrabal v PC konkretne v ATITOOL konkretne 0.27 a v driver setings a tam som nasiel tuto moznost Vid nazov temy co to znamena? lebo tam sa udavaju cisla asi konkretne fps je to drzanie fps ? ked napr zadam cislo 60 a ked to klesne pod daco sa zapne sa niaka funckia alebo co kto ma s takym dacim skusenosti piste

Temporal Anti-Aliasing

With the incredible performance of the RADEON X800 series of VPUs, it is not uncommon to see games running at frame rates that match or exceed the refresh rate of the display device (typically 50-60 frames per second for LCDs, and 70-85 frames per second for CRTs), even at high resolutions with anti-aliasing and anisotropic filtering enabled. Since the displays cannot update any faster than this, the additional frames provide little or no benefit to image quality.

Temporal Anti-Aliasing is a new technique that uses the programmable sample pattern capability of SMOOTHVISION HD to improve image quality in these cases. It works by alternating between two different pre-defined sample patterns every frame. This causes a slight fluctuation in the colors of anti-aliased edges that is visible at low frame rates. However, as the frame rate approaches the display refresh rate, the persistence of the display causes the results of the two sample patterns to combine into a single result. This produces an image that appears to have twice as many samples per pixel as it actually does, providing a significant image quality benefit with no performance impact. The effect is particularly striking with 2x temporal MSAA, where the resulting image is virtually indistinguishable from standard 4x MSAA yet runs much faster.



Temporal anti-aliasing works anywhere that standard MSAA can be used. In order to avoid the flickering artifacts that can occur at lower frame rates, it can be temporarily disabled by the driver if the frame rate drops below a defined threshold, and re-enabled when they climb back above it. In this case, the display would revert to standard MSAA.




Strucne zlepsuje to kvalitu obrazu pokial mas prilis vykonnu kartu a pri zobrazeni s AA a AF ti uz monitor nesitha(fps je vyssie ako obn. frekvencia monitora) tak to spaja dva framy do jedneho = kvalitnejsi obraz a to nastavenie tam je ze ked to robi problemy(rozne artefakty) tak si nastavis fps od ktoreho dolu sa to vypne.asi

tak ale ja vykonnu kartu nemam mam Radeon 9600SE 64bit 128MB takze mam nastavit vyssie cisla alebo mensie ?

Radsej ziadne

Ako povedal michigen...radsej tam nedavaj nic. Pri tvojej karte si nemozes dovolit ani filtrovanie

No zas taky sunt 9600 nie je a naviac AF zatazuje graficke jadro a nie Bandwidth pamati, ale AA by tu kartu dostal nakolena, hadam je kazdemu jasne preco

[miqra]

pokles vykonu 9600viek pri AF bolo vzdy do 20%... AA pri 64bit zbernici = -30-40% vykonu

tak karta az taky shit neni splinter cell 3 mi bezi pekne na 800x600medium a to je uz shader model 2 rozbehal by som aj 4 rku ale to s problemamy aj call of juarez mi pekne ide len pri starsich hracch otrasne fps klesa priklad counter strike takze skusim dat hodnutu 0 uvidim ze ci bude tak klesat fps ato som este nepochopil dam tam priklad hodnotu 50 a to AA sa mi zapne ked fps klese pod alebo nad 50 ?

[killswitch]

call of jurez ti ide pekne na 9600? ja vlastnim 16 pipe 6800 a call of juarez si nezahrajem...

a to AA sa mi zapne ked fps klese pod alebo nad 50

klesnut nad 50 asi nemoze, ale zapne sa to, ked fps stupne nad zvolenu hranicu (v tvojom pripade nad 50).

1.) by som na tvojom mieste TAA nezapinal

potrebujes minimalne 60fps a viac, inak budes mat na celom obrazku shimmering a vo viacerych scenach "nepomaha" ani tych 60fps - putovanie hran je jasne viditelne

mohli by sme debatovat aj o zmysle tejto moznosti, nakolko sa daju najst hry, kde nie je vidiet ziadna pozitivna zmena.

hlavny problem je, ze s TAA sa zapne aj AI a preto mozes na trilinearny filter zabudnut (u starsich Radeon grafickych kartach)

2.) pokial nemas zapnute TAA je nastavenie Temporal AA Frame Threshold bezpredmetne
---------------------------------

este by som dodal k tomu textu z Driverheaven ...

TAA podporuju len radeon graficke karty
pocet masiek pri TAA sa moze okrem zdvojnasobenia aj strojnasobit

strata vykonu TAA je rovnaka ako pri zapnuti obycajnych MSAA modov

call of jurez ti ide pekne na 9600? ja vlastnim 16 pipe 6800 a call of juarez si nezahrajem...

klesnut nad 50 asi nemoze, ale zapne sa to, ked fps stupne nad zvolenu hranicu (v tvojom pripade nad 50).

tak ano call of juarez mi ide pomerne solidne 800x600 setko efekty low (aj pri tych low je to velmi prepracovane) a pomerne pekne plinulo to ide a pritom nesplnam zakladnu podmienku tam musi byt R9800 a vyssie no zazrak lebo ta hra je vyvinuta len cisto na nvidiu no proste stare zelezo rulezz

....

no presne to som chcel vediet vsak akoze ja som pogoglil som vedel ze co to znamena len som nevedel ci to drzi alebo znizuje kvalitu obrazu a ci sa to vobec oplati na mojej karte ale toto nastavenie AK by aj som zapol tak ten mensi vykon skor klesa len v prepracovanejsich hrach alebo aj v tych starsich mne len tak o Counter strike ide inu hru ani moc nehram takze chcem dostat max vykon od karty.
