GRAW II

All pictures features in this review are with GRAW 2 running at highest detail settings at 1280*1024 with PhysX turned to extreme. The test PC used was as follows:

E6600 @ 3.15ghz
MSI P6N-Diamond
Sapphire x1900XT
Asus PhysX PPU
Silver Power 600w

The main single player in GRAW 2 has quite a few PhysX “effects” in it that are quite noteworthy. First up, there are wooden buildings and fences everywhere and they can all be manipulated with the weaponry you carry with you – not to the extent that they can on Ageia Island, but we will discuss that later.

Take the one that surrounds the edge of the first level for example. Take some pot shots at that and you can see the planks fall one by one onto the ground. In general they fall with a standard animation, but bits fly off them in when PhysX set to “Extreme” whereas in “Normal” mode with no hardware support, the fence boards simply fall over; no flying chunks of wood to be seen.

In both Normal and Extreme PhysX modes, when a grenade is thrown at a fence, it sends the pieces flying. However, there are significantly more pieces when in Extreme mode and there is also no real frame drop, compared to normal where lag is abound.

Another PhysX effect that is quite a spectacle are the explosions. With physics on full, the debris fly everywhere, whereas without, there is no debris at all, and is a little under whelming when having played in Extreme mode previously.

You can also shoot out the supports on metal fences, causing them to collapse. This is available in Extreme and Normal PhysX settings, however in the latter the sheets collapse quite mundanely whereas with full PhysX enabled, dust and pieces of wood fly from the boards as the fence fall. This is a perfect example of in-game physics being used to alter the way that we play through the level.
