Feature TestsThe feature tests are what we consider to be the most interesting for our purposes at PC Perspective as they allow us to isolate specific GPU areas for testing and comparison.
Feature Test 1: Texture Fill
This fill rate test pushes as many pixels as possible through the GPU by using a very small texture sample and rotating/scaling it from frame to frame.
Feature Test 2: Color Fill
The color fill test uses a pass-through shader to fill the screen with slightly animated corners and center with alpha and color values shifting slightly.
Feature Test 3: Parallax Occlusion Mapping (Complex Pixel Shader)
The Parallax Occlusion Mapping test uses a 4k x 4k height map to represent a variable height landscape. Lighting is also applied to the effects to produce a pretty amazing scene.
Feature Test 4: GPU Cloth
The cloth simulation test renders twelve flags all on the GPU using both geometry and vertex shaders. This doesn’t use the AGEIA model but instead uses a general purpose GPGPU calculation model.
Feature Test 5: GPU Particles
A scene using hundreds of thousands of particles, again all rendered on the GPU.
Feature Test 6: Perlin Noise (Math-heavy Pixel Shader)
An update Perlin noise test is included in 3DMark Vantage that uses a very math-intensive pixel shader to generate the color affects you see on screen.
