Oblivion doesn't have an integrated benchmarking utility. To test performance, we use FRAPS in this benchmark.

In Oblivion there is a clear difference between the performane of the 8600 GTS cards and those of the 8600 GT family. The test highlights a large performance difference between the two card classes.

The line graph shows how the cards perform over the 30 second test. Again, the difference between the 8600 GTS and GT cards is quite apparent.
