Of course, we were very interested in how much performance losses can be expected by switching on the various Smoothvision levels. We tested this under OpenGL with the help of Quake 3.
Given the fact that one In order to be able to play Quake 3 smoothly, which needs at least 60 fps per second, with these settings and the resolution there is at least 5x performance and 4x qualityinside.
At a higher level of detail, only 4x performance and 4x quality are acceptable in the selected resolution .
At a resolution of 1024x768, the frame rate breaks down properly, the 3x performance level is still suitable for smooth gaming, but only 2x quality level is still there is - 3x, 5x, 6x are due to the limitation of Au Solution not available.
Ouch, only 2x performance is just usable here, the performance drop is enormous, it is alone here already 60%!
Let's take a look at the frame rates achieved by the FSAA methods of the GeForce3 in comparison:
The GeForce3 does not get into any of the critical areas and thus both resolutions are at normal detail in all FSAA modesplayable without stuttering.
The GeForce3 in none of their FSAA modes below 60fps. The comparison between the FSAA performance of the two cards is really difficult. What is certain, however, is that activating Smoothvision at a resolution of 1024x768 and higher with high details is completely superfluous, since from then on smooth gameplay is no longer guaranteed. One can only hope that ATi will optimize its drivers a little more to solve these performance problems. Only at lower resolutions such as 800x600 can the performance of Smoothvision still be used with high details, the only question is whether it is sometimes better to run 3 resolutions higher.
