It’s obvious that none of the graphics cards from this category can run TES IV: Oblivion at an acceptable speed. Perhaps the GeForce 7600 GT that has the best technical parameters of all is an exception, but not a very good one. The average performance of this graphics card is about 40fps in closed environments, but its min speed isn’t higher than 20fps if you use the game’s maximum graphics quality settings.
It’s even worse in open scenes with lots of vegetation. The GeForce 7600 GT hardly overcomes the 20fps point while the rest of the graphics cards yield 15fps at best. The Radeon X1600 XT with only four TMUs is no rival to the GeForce 7600 GT and is even slower than the GeForce 7600 GS which works at lower GPU and memory clock rates but has 12 TMUs and 8 raster operators (ROPs).
All that we’ve just said refers to the resolution of 1280x1024 pixels because in higher resolutions even the GeForce 7600 GT is beneath criticism. If you’ve got one of these graphics cards and want to play Oblivion, you have to disable HDR and lower the level of detail to achieve an acceptable speed. This isn’t good, of course, but that’s how advanced the visuals of this game are: TES IV is a huge burden for any computer’s graphics subsystem.
