Earlier Splinter Cell games in the series tended to look better on the Xbox than the PlayStation 2 since the series was built around the more powerful hardware of the former. Because current-generation consoles are comparable in power, it's not surprising that the PS3 version of Double Agent looks almost as good as the Xbox 360 version, though there are some issues. For instance, the PS3 version lacks some of the complex lighting and shadowing effects that were put to great use in the Xbox 360 version, immersing you in the gloom. Meanwhile, night vision lacks the warm, glowing amplification of lights seen in the Xbox 360 version, and the PS3 version doesn't have some of the 360 version's particle effects, such as smoke plumes.
