Performance in RPG
The Elder Scrolls IV: Oblivion
The Nvidia GeForce 7 architecture doesn’t allow using HDR (FP16) along with FSAA. That’s why we tested the cards in TES: Oblivion at the “pure speed” settings only: without HDR the game loses much of its visual appeal. The speed of the cards was measured with the Fraps utility, so the numbers may be somewhat inaccurate.
Fast execution of pixel shaders is important in closed scenes, so the Radeon X1950 XTX is just a little ahead of the Radeon X1900 XTX. The new memory should show its best in open scenes of the Tamriel world. We guess that the lower minimum speed of the new Radeon in 1920x1200 is most likely due to an error during the manual benchmarking. Note also that despite having a total of 48 pixel processors, the GeForce 7950 GX2 is slower than the single-chip cards from ATI in terms of minimum speed in resolutions up to 1600x1200.
The performance of the Radeon X1950 XTX has really improved relative to its predecessor in open environments of this game, but the difference isn’t as big as we had anticipated. Perhaps the 16 TMUs of the new card limit its performance somewhat. Anyway, the new Radeon takes the first place among single-chip cards, once again confirming the fact that ATI R580-based products are best for playing Oblivion.
Fast memory doesn’t have a big effect on performance in Titan Quest, either. In this Diablo clone you only need an average speed of 30-40fps for comfortable play. It is also desirable that the speed be always higher than 25fps. All modern graphics cards from the premium and high-end categories equipped with 512 megabytes of graphics memory can give you that speed. The GeForce 7950 GX2 acts up in 1280x1024 for some unclear reason, but regains its strength in higher resolutions.
