One more disadvantage is that, due to separating the lighting stage from the geometric stage, hardware anti-aliasing does not produce correct results anymore since interpolated subsamples would result in nonsensical position, normal, and tangent attributes. It's possible to use many different materials, but it requires more data to be stored in the G-buffer, which is already quite large and takes up a large amount of the memory bandwidth. When order-independent transparency is desired (commonly for consumer applications) deferred shading is no less effective than forward shading using the same technique.Īnother serious disadvantage is the difficulty with using multiple materials. Modern hardware, supporting DirectX 10 and later, is often capable of performing batches fast enough to maintain interactive frame rates. Depth peeling can be used to achieve order-independent transparency in deferred rendering, but at the cost of additional batches and g-buffer size. One key disadvantage of deferred rendering is the inability to handle transparency within the algorithm, although this problem is a generic one in Z-buffered scenes and it tends to be handled by delaying and sorting the rendering of transparent portions of the scene.

These advantages may include simpler management of complex lighting resources, ease of managing other complex shader resources, and the simplification of the software rendering pipeline. There are some other advantages claimed for the approach. This gives the ability to render many lights in a scene without a significant performance hit. Only one geometry pass is required, and each light is only computed for those pixels that it actually affects. The primary advantage of deferred shading is the decoupling of scene geometry from lighting.
