Far Cry with HDR
The GeForce 7900 GTX has an excellent result in Far Cry’s HDR mode, surpassing the Radeon X1900 XT CrossFire in high resolutions. The GeForce 7800 GTX 512 isn’t far behind, though, despite the lower graphics core clock rate – the newer card from Nvidia is only 3-4fps faster at best.
Just to remind you, the high dynamic range mode of Far Cry still doesn’t work well on graphics cards with ATI Technologies’ GPUs – their performance is far from optimal then.
The GeForce 7900 GTX performs in the same way on the Research map. You can play the game in 1600x1200 using HDR.
Unfortunately, you cannot improve the picture quality further by turning on full-screen antialiasing. The GeForce 7 architecture cannot smooth textures in FP16 format and thus doesn’t allow using FSAA and HDR at the same time. This option is available with ATI’s Radeon X1000 series, but ATI’s cards cannot filter such textures and have to emulate filtering by means of a special shader.
