The Elder Scrolls IV: Oblivion GPU Performanceby Anand Lal Shimpi on April 26, 2006 1:07 PM EST

We tested at two major settings, one we defined as High Quality and the other we called Medium Quality. The settings were as follows:
|Oblivion Performance Settings||High Quality||Medium Quality|
|Shadows on Grass||On||Off|
|Tree Canopy Shadows||On||Off|
Note that when we talk about a setting being 65% we mean that the slider is moved 65% of the way to the right. As you can see from the table above, our High Quality settings aren't as extreme as they could be and the Medium Quality settings are more suited for upper mid-range cards. Since we were dealing with such a wide spread of GPUs we had to err on the side of being more stressful in our visual settings, especially in the mid-range, in order to adequately characterize the performance of all of the GPUs. We didn't want to end up with a graph where everything performed the same because we were too lax with our detail settings.
At the end of the day, these two configurations are what we would strive for in order to get good performance while maintaining a good gameplay experience.
High End Settings
Mid Range Settings
Note that the ATI Radeon X850/X800 series of GPUs don't support Shader Model 3.0, which is required for HDR in Oblivion. Thus we had to leave the X850/X800 out of our default tests with HDR enabled and ran a second set of configurations with HDR disabled and Bloom enabled.
