大家好似要出火了
我又想講下PS3隻KZ2
E野隻好多外國網站話超越左CRYSIS
咁一向比人話256RAM 的7800GT的PS3
又點解可以做到咁既?




有關CELL的處理
http://en.wikipedia.org/wiki/Ps3
The PlayStation 3 uses the IBM-designed Cell microprocessor as its CPU,utilizing seven of the eight "synergistic processing elements" (oftenshortened to SPE). The eighth SPE is disabled to improve chip yields(i.e. chips do not have to be discarded if one of the SPEs isdefective). Only six of the seven SPEs are accessible to developers as one is reserved by the OS.Graphics processing is handled by the NVIDIA RSX 'Reality Synthesizer',which can output resolutions from 480i/576i SD up to 1080p HD. ThePlayStation 3 has 256 MB of XDR main memory and 256 MB of GDDR3 videomemory for the RSX.

Killzone 2 only using 60% of SPU's overall power?
Posted on December 5th, 2008 at 06:11 EDT
Speaking in IGN's latest Play Beyond podcast, Jeff Haynes revealed that even during the heaviest loads, Killzone 2 utilizes roughly only 60 per cent of the SPU's.
"It's incredible to see huge levels and see the deferred rendering andnote that on all the SPU’s, even on the heaviest load were coming up toabout 60%," Haynes said. "They weren't coming close to maxing out..They had about 40% of space before they started tripping or saw slowdown on some of the processes."
Furthermore, Haynes noted that the preview codes recently distributedto various media outlets were of an alpha build of the title, and havesince been polished up . Visiting Guerilla Games in Amsterdam, Hayneswas shown an updated version of the game, mid to late beta, noting thatelements such as lighting, cut scenes, glitches, load times, have allbeen optimized.
Killzone 2 is due out exclusively on PlayStation 3 on February 27, 2009.
點做法:將Graphic/sound要做計算如風動態,環境光,身體動作,光影,音效等視聽效果全部用6粒SPE計算,所以咁多效果都對Game本身速度無影響
有乜好處:可以做好多效果而都對Game本身速度無影響
壞處/有無limitation:隻Game只可以响PS3執行 |
