	Tile-Based Deferred Shading Optimized G-Buffer Layout Manual MSAA Resolve in a Compute Shader The greyscale image shows the number of visible lights per tile. Higher values mean more lights computed in the respective tile. The color image is the result, which does not differ much from the original rendering other than being rendered more efficiently. The final compute-based rendering path in this exercise renders up to four times faster than the initial unoptimized fragment shader (NVIDIA GTX 850M, 110 light sources => 4.7 fps vs. 15 fps @ 1920x1080).
