Note: best experienced with Firefox browser -- Chrome works, but does not always reach 240 Hz.

After the images are loaded, please allow some time for the browser to warm up before viewing the results.

You require access to a 240 Hz display to see the effect of the image sequences below.

You can change the framerate at which image sequences are shown with the
radiobuttons below the images. The choices are based on the measured refresh
rate of your monitor.

Section 2: The Power of 240 Hz

• Static edge
• Dynamic edge
• Monte Carlo noise
• 60 versus 240 FPS

Section 3: Our Approach

• Temporally dense vanilla rendering (1 out of 4 pixels, no filtering)
• Reflected motion vectors
• Clamp footprint
• Pixel ordering comparisons:
• • Bowtie versus hourglass versus adaptive
  • Bistro #1 (0 < α ≤ π/4 - γ)
    
  • Bistro #2 (π/4 - γ < α < π/4 + γ)
    
  • Bistro #3 (π/4 + γ ≤ α < π/2)
  • Pattern selection during arbitrary motion

Section 4: Results

• 60 FPS vanilla versus 60 FPS TAA versus ours at 240 FPS:
• • Bistro
  • LivingRoom
  • Cerberus
  • Hairball
• 60 FPS vanilla versus ours at 240 FPS versus 240 FPS vanilla:
• • Bistro

Other

• User study:
• • Bistro 1
  • Bistro 2

For the best viewing experience, we recommend the following:

• Close all other applications and browser tabs.
• Run directly, not in a virtual environment like Remote Desktop or VMWARE.
• Enable GPU acceleration.
• Enable Aero in Microsoft Windows.
• Use a single monitor. If multiple monitors, use primary.
