In Anlehnung an die zahlreichen Fragen beim gestrigen NVIDIA Themenabend bezüglich des unglücklichen 3DMark03-Tunings (wir berichteten), hat uns NVIDIA heute ein paar offizielle Statements dazu zukommen lassen:
Futuremark Statement
For the first time in 6 months, as a result of Futuremark's White Paper last Friday, Futuremark and NVIDIA have had detailed discussions regarding NVIDIA GPUs and Futuremark's 3DMark03 benchmark.
Futuremark now has a deeper understanding of the situation and NVIDIA's optimization strategy. In the light of this, Futuremark now states that NVIDIA's driver design is an application specific optimization and not a cheat.
The world of 3D Graphics has changed dramatically with the latest generation of highly programmable GPUs. Much like the world of CPUs, each GPU has a different architecture and a unique optimal code path. For example, Futuremark's PCMark2002 has different CPU test compilations for AMD's AthlonXP and Intel's Pentium4 CPUs.
3DMark03 is designed as an un-optimized DirectX test and it provides performance comparisons accordingly. It does not contain manufacturer specific optimized code paths. Because all modifications that change the workload in 3DMark03 are forbidden, we were obliged to update the product to eliminate the effect of optimizations identified in different drivers so that 3DMark03 continued to produce comparable results.
However, recent developments in the graphics industry and game development suggest that a different approach for game performance benchmarking might be needed, where manufacturer-specific code path optimization is directly in the code source. Futuremark will consider whether this approach is needed in its future benchmarks.
NVIDIA Statement
NVIDIA works closely with developers to optimize games for GeForceFX. These optimizations (including shader optimizations) are the result of the co-development process. This is the approach NVIDIA would have preferred also for 3DMark03.
Joint NVIDIA-Futuremark Statement
Both NVIDIA and Futuremark want to define clear rules with the industry about how benchmarks should be developed and how they should be used. We believe that common rules will prevent these types of unfortunate situations moving forward.
Offensichtlich ist Futuremark davon abgekommen, die Tuning-Maßnahmen des nVidia-Treibers als Cheat zu bezeichnen und spricht diesbezüglich nun offen von einer Optimierung des Programms an die GPU des Grafikherstellers, wie es auch bei den Prozessoren seit langem üblich sei.
