S obzirom da ova tema ima veze s DX10 testovima i performansama 8x00 serija u istim, evo šta kažu na vr-zone.com :
The Call of Juarez Benchmark released last Friday is one of the first few DirectX 10 benchmarks for public to try out. According to NVIDIA however, the benchmark includes new code that substantially reduces performance of NVIDIA hardware. Basically, it is claimed to be very skewed towards ATi hardware. The key issues brought up are:
NVIDIA's DX10 hardware-based multi-sampled Anti-Aliasing resolve is disabled in the benchmark, with all NVIDIA GPUs now being forced to use software-based AA resolve similar to the ATI DX10 GPU (which lacks hardware AA resolve). This artificially deflates performance on NVDIA graphics cards and users are not getting the benefit of a key NVIDIA hardware feature.
A hidden "ExtraQuality" parameter only accessible via a configuration file is automatically enabled when the benchmark is run on NVIDIA hardware, no matter what the setting in the configuration file. This setting has no apparent visual quality enhancement, but reduces NVIDIA GPU performance.
Changes to shaders that deflate NVIDIA performance by approximately 10-14%, without improving visual quality on either NVIDIA or ATI GPUs.
It is interesting to see that battle on the GPU frontier seems to have spilt over to the games.
