PureHair
PureHair is Crystal Dynamics and Square Enix's hair rendering technology, which like our own
HairWorks technique adds tens of thousands of hair strands to a character model. These hairs move realistically, can be affected by wind and water, and are lit and shaded in real-time by the scene.
In
Shadow of the Tomb Raider, the 'Normal' setting is recommended for just about everyone, as 'Low' strips back the number of hairs for min-spec users who need to disable and turn down as many settings as possible.
In the normal gameplay position, with Lara away from the camera, the difference between detail levels is far less noticeable, though as Lara walks, runs and jumps, the degree of hair movement and its realism are still affected.
In cinematic, story-driven cutscenes, however, the differences between detail levels are immediately apparent, as Lara almost-always takes key billing, with lots of close-ups and action moves highlighting the immersion-damaging loss of hairs.
Performance: As with other hair rendering technologies, dynamic level of detail scaling adjusts the visual quality and performance of hair on the fly. During gameplay, in the default zoomed-out view, expect a minimal performance cost of just 2-3 frames per second, versus Low, though that number raises to 5 or 6 frames per second when you zoom in for precision sniping or shooting.
In cutscenes, the performance cost can be up to 10 frames per second, but as performance is often higher during these moments the extra hit is offset and shouldn't be a problem for most systems.
