The frame per second cap (CPU bottleneck we assume) seems to have moved up to 88fps from around 60fps when using the ultra high quality settings. The GeForce GTX 280/260 and all the Radeon HD 4870 based graphics cards reached this rate on average at 1440x900.
These quality settings at this mild resolution proved to deliver very playable performance on even the Radeon HD 4670 graphics card which averaged 50fps, making it the third slowest graphics card tested.
Again increasing the resolution took a noticeable toll on performance dropping the Radeon HD 4870 and GeForce GTX 260 graphics cards to a very smooth 80fps. The Radeon HD 3870 is about as slow as we'd go, rendering 46fps on average at 1680x1050.
This means that the Radeon HD 3850, 4670, 4650, and GeForce 9500 GT all failed to make the cut. The GeForce 9600 GT was again impressive averaging 60fps which was higher than the much more expensive Radeon HD 4850.
Here we are once again at 1920x1200 where the GeForce 9600 GT still manages to render 51fps, matching the 9800 GT. The 9600 GSO managed just 40fps, while the Radeon HD 3870 was limited to 39fps as was its dual-GPU version.
The Radeon HD 4850 managed to beat the 9600 GT this time rendering 54fps, while the age old GeForce 8800 GTX fared better with 61fps.
