Users of older computers will of course also benefit from a number of improvements. The tiled texture cache severly reduces the memory footprint of the renderer, so you can put a lot more textures and bigger textures in your scenes than ever before, without running out of memory. The improved raytracer and the irradiance cache can significantly speed up the rendering of scenes that use ambient occlusion. Occlusion culling and the improved depth of field also provide a better rendering experience on old and new computers.
