The deferred shading demo at 50FPS on a GTX 660
The code sample pack of the OpenGL SuperBible 6th edition has been updated few days ago.
I compiled all code samples for Windows and put all binaries and media together so you can now easily and quickly test a demo. All binaries are available in the bin/ folder of the zip archive. You can download this improved pack right here:

Here is the deferred shading demo from this code sample pack:
This is a simple example of deferred shading implemented using OpenGL. The demo shows 100 ladybugs lit by 500 point lights and runs at 60Hz on AMD Radeon HD 7970. The application uses a brute force approach and lights every pixel with every light. Using light culling and a tiled approach, much higher performance could be achieved.
The code sample pack includes also other interesting demos like DoF (depth of field), SSAO (screen space ambient occlusion) and more…
