TessMark is an OpenGL benchmark and tech demo that uses the new hardware tessellation (or GPU tessellation) features exposed by the OpenGL 4 API
and available on the latest graphics cards like the NVIDIA GeForce GTX 480 or the ATI Radeon HD 5870. Hardware tessellation makes it possible
to divide a polygon into smaller ones (according to the tessellation level factor) in order to increase polygons density: the higher the tessellation level, the higher the polygon density.
A high tessellation level requires much GPU processing power.
Hardware tessellation (OpenGL 4 or Direct3D 11) requires GeForce GTX 400 Series (like the GTX 460, GTX 470 or GTX 480) or Radeon HD 5000 Series (like the HD 5770 or HD 5870).
TessMark proposes four fixed tessellation levels: moderate, normal, extreme and insane:
Extreme and unbearable are reserved for GPUs with much tessellation processing power...
The benchmark includes several options allowing the user to tweak the rendering: fullscreen or windowed mode,
MSAA selection, window size, duration of the benchmark.
