Driverheaven Farcry Benchmark / 6800 Performance There have been a few storyâ€™s circulating on the Internet today regarding 6800Ultra performance in Farcry and how IQ is impacted when the Device ID is changed. Last weekend we tested Farcry under these conditions for our upcoming 6800 Ultra review however based on the fact that information has become widely available on the subject today it may be useful to know what our findings regarding performance were when these IQ changes were made. Test System: Amd Athlon 64 FX-53 ASUS SK8N 2x512mb DDR433 Supplied and thanks to Corsair AKASA AK-855 Cooler Nvidia Geforce 6800 Ultra 256mb Gainward Geforce FX 5950 Ultra 256mb Sapphire Radeon 9800 XT 256mb IBM Deskstar 120 GXP 40GB 7200rpm Hard Drive Sony CRX300E DVD/CDRW Sony Floppy Drive Mercury 400W PSU AOC 19â€ 9GLR CRT Software: Windows SP1a Direct X 9.0b / SDK Forceware 60.72 (6800) Forceware 56.72 (5950) WHQL Catalyst 4.4 WHQL Nforce Driver 3.13 Farcry with 1.1 patch 3dAnalyse latest build Fraps latest build The test system was built from scratch, a format of the hard drive was performed (NTFS) and then Windows XP was installed. Following the completion of the install the N-force drivers were installed. The only updates applied were SP1a and Direct X 9.0b. Following a reboot the 60.72/56.72/4.4 drivers were installed. Next the benchmarking tools were installed and finally the hard drive was de-fragmented. For all tests the Nvidia/ATI drivers were set to best image quality. This included manually setting trilinear in mipmaps and manually disabling Trilinear optimisations. As you can see the results are considerably different for the 6800 when the R300 device ID is forced. In addition to the 6800Ultra then using the same pixel shaders as the Radeon card the display issues which are well documented on the internet are fixed by using the Radeon path. In summary, forcing the R300 path if you have a 6800 Ultra is advisable as it gives you decent performance however better IQ than the standard path. One other point of note is that the Radeon 9800XT is very close in performance to the 6800Ultra at the same IQ levels. Only 7fps in average framerates separate the cards which is a phenomenal result for the Radeon. It may be interesting to hear what Nvidia have to say about why they donâ€™t run a fully working path by default? After all, surely they should be providing their customers with the best experience possibleâ€¦shouldnâ€™t they?
