| 5 | Stutters – This game is very likely to stutter and have poor frame rates. Based on all known benchmarks using the specified graphical settings, average frame rates are expected to fall below 25fps |
| May Stutter – This graphics card has not been explicitly tested on this game. Based on interpolated information from surrounding graphics cards of similar performance levels, stutters and poor frame rates are expected. | |
| 30 | Fluent – Based on all known benchmarks using the specified graphical settings, this game should run at or above 25fps |
| 40 | Fluent – Based on all known benchmarks using the specified graphical settings, this game should run at or above 35fps |
| 60 | Fluent – Based on all known benchmarks using the specified graphical settings, this game should run at or above 58fps |
| May Run Fluently – This graphics card has not been explicitly tested on this game. Based on interpolated information from surrounding graphics cards of similar performance levels, fluent frame rates are expected. | |
| ? | Uncertain – This graphics card experienced unexpected performance issues during testing for this game. A slower card may be able to achieve better and more consistent frame rates than this particular GPU running the same benchmark scene. |
| Uncertain – This graphics card has not been explicitly tested on this game and no reliable interpolation can be made based on the performances of surrounding cards of the same class or family. | |
| The value in the fields displays the average frame rate of all values in the database. Move your cursor over the value to see individual results. | |
