Gameplay Notes
In our Oblivion walkthrough, which covered approximately 2,000 frames in an outdoor area, performance was acceptable at the resolution of 2560x1600 with 4x antialiasing on the EVGA GeForce GTX 260 Core 216 Superclocked. However, a slight hint of sluggishness became apparent in areas with heavy foliage. Turning down in-game foilage settings a notch or two will improve performance in these types of situations.
With Crysis at the high setting under Windows XP, the EVGA GeForce GTX 260 Core 216 Superclocked dipped to a low of 18 frames per second during intro level gameplay. Performance was sluggish at the super-resolution of 2560x1600.
S.T.A.L.K.E.R. performance was slightly sluggish at this resolution as an average/minimum frame rate of 44/25 was recorded during gameplay.
