In this short section we will be taking the results from the Heaven benchmark tests on the previous page and plotting them on a comparative graph.
There should be a number of things which are immediately evident from this graph. First of all, it seems like ATI’s cards do indeed take a harder performance hit than the GF100-based cards when tessellation is enabled, but not by a significant amount. However, NVIDIA’s high end card once again seems to choke a bit at high resolutions. ATI’s HD 5870 stays even when going from 1920 + tessellation to 2560 + no tessellation but the GTX 480 on the other hand looses nearly 20% of its performance.
The exact reasoning behind this isn’t quite clear at this time, and NVIDIA is still looking into the problem. However, from what we have already shown you, this isn’t the only application which shows the exact same performance drop-off.
