Spinel Performance — Technical Paper

This example demonstrates a 4-page technical paper that has both text and fine line art.

Like the last post, there is no intelligent instancing of glyphs in the vector graphics source. From the Spinel pipeline’s perspective, every glyph on the page is a unique path. A proper implementation of a viewer or editor would use Spinel’s fast paths for instancing.

The 4-page technical paper is rendered by Spinel on a GTX 980 at 4K.

With Vsync off, the paper renders at 273-683 FPS.

With Vsync on, the frame rate is locked at 60 FPS and shows low GPU utilization:

• GPU load: 12-22%
• MEM load: 10-12%
• Power: 35-37% of TDP
