Ageia PhysX - karta ciste na fyziku
NV PhysX - graficka karta zvlada oboje, graficka karta ciste na fyziku
Jak muze byt starsi reseni lepsi?
To uz nemluvim o tom, ze Ageia narazila na problem slepice/vejce. NV uz ma ted prodano nekolik milionu karet schopnych fyziku akcelerovat.
But of course, the unlimited evilness of the ultimate tool of mischief, the universal explanation for sucky performance from anything other than nVidia, TWIMTBP, strikes again. The shenanigans know no bounds....luckily, in this sea of pain and anguish,the shining beacon of light and righteousness, ATi, stand, with their Get in the Game program that they managed so badly(because they`re not evil like nV, see, so they couldn`t actually have a program where they worked really close with devs, pushing their tech into their stuff) that no game is part of it. - Morgoth the Dark Enemy

Tak
1. Graficky vykon je i dnes zasadni. Mnohem podstatnejsi nez fyzikalni akcelerace. Pokud zapnes akceleraci PhysX, tak ti FPS poleti dolu, obcas az na polovinu, takze si musis hodne rozmyslet, co je pro tebe dulezitejsi. Jestli je to detail, antialiasing, pocet FPS nebo fyzika.
2. Resenim je samozrejme SLI, ale i tam se zapnutim PhysX pripravis o graficky vykon SLI. V tomto pripade az o 50% vykonu, protoze jedno GPU pocita fyziku a zase trpi graficky vykon... Navic je to reseni uz stejne jako s PhysX. S jedinym rozdilem... je to pomalejsi nez 1 graficka karta + PhysX PPU.
3. Jako dukaz mas UT3. Hral jsem ho na GTX280 s PhysX a opravdu je to pouze tech demo na podivani se. Na zadny hardcore gameplay to rozhodne neni(min. FPS <20). Nehlede k faktu, ze to uz ma lepsi fyziku Crysis, ale to jen tak na okraj.

Re: NVIDIA novinky
Ehm...
SLI pro PhysX vubec neni potreba. Muzes pouzit jakekoliv dve NV karty na jakemkoliv chipsetu. Druha muze byt klidne nejaka 8600 za par supu. V tomhle pripade je vliv na FPS minimalni a prinos pro realisticnost je daleko vyssi. Kdyz uz, tak jde provozovat SLI + dalsi GPU na PhysX.
Stejne jako driv lide nezapinali AA, protoze na to chybel vykon, tak si v dnesni dobe rozmysli zapnuti PhysX, ovsem pouze pokud vlastni jednu kartu. S roustoucim vykonem se situace muze zmenit a pochybuju, ze naroky na vykon GPU/PhysX karty poleti tak rychle nahoru, aby si je musel nejak casto menit.

Re: NVIDIA novinky
PhysX PPU, ktere ma fyzikalni vykon vic jak 20x vyssi nez 8600, stoji kolem 2300Kc, tj. temer stejna cena. Takze tu vyhodu druhe grafiky na fyziku nevidim ani v tomto

Re: NVIDIA novinky
Cely test proveden na 9800GTX. Vazne bude to PPU tak silne, kdyz jedna karta, ktera pocita oboje podava takove vysledky?

Re: NVIDIA novinky
Ano bude. Problem je, ze se tu projevuje zpomaleni z duvodu callu. Kdyz mas PhysX PPU, tak mas dvojnasobek callu. 1x na grafiku a 1x na PPU. Ten vykon by se projevil az u velmi narocnych fyzikalnich simulaci. To mas jako bys benchmarkoval GTX280 v 1024x768 na medium detaily a na stejnych detailech to pomeroval s 8800GT
Navic ten graf neodpovida realite. Je snad mereny pri FLyBy

Re: NVIDIA novinky
No ja jsem ted schvalne hledal, jestli nekde testovali PPU vs GPU ciste ve fyzice a nikde jsem nic nenasel. Mas nekde neco o tom 20-ti nasobnem vykonu? Tomu mam problem uverit.
