    Default Shader Optimizations Greatly Speed-Up Wayland

    Phoronix: Shader Optimizations Greatly Speed-Up Wayland

    Rob Clark, the Texas Instruments developer known for his work on the OMAP DRM driver, DMA-BUF, and hacking a Qualcomm open-source driver in his spare time, has been dabbling with Wayland. Rob's done some optimizations and simplifications to shaders used by Wayland's Weston reference compositor that greatly improve the performance...

    This is confusing. I think you can remove "Previous to this work"?

    Previous to this work, when trying to run Wayland on a small SoC GPU like the TI OMAP4 PandaBoard at 1080p, he can obtain 60 FPS while pushing around windows. When pushing YUV buffers for hardware-accelerated decode of 1080p videos he gets 30 FPS. These numbers are compared to below 30 FPS and about 6 FPS, respectively, before writing these optimized shaders.

    Michael is confusing "Weston" with "Wayland" in the title.
