This Quadro™4 XGL Series Performance Guide contains essential information to assist you in the review of the Quadro 4 XGL series of professional graphics solutions. Included are important hardware optimizations, review tips, benchmark settings and other miscellaneous “gotchas” found while testing and benchmarking. Here’s a quick list of what we’ll be reviewing: General Benchmark Reminders NVIDIA’s Unified Driver Architecture (UDA) Test with Windows XP Recommended Benchmarking Applications Testing NVIDIA nView Multi-display Technology Sample Benchmark Data While benchmarking, we’ve encountered a number of issues that you should be aware of.

Here is a checklist of the things to look for when your numbers don’t match some of the numbers provided, or when applications will not run: NVIDIA recommends testing at a minimum resolution of 1280×1024 x 32-bit with a refresh rate of 75Hz. NVIDIA-designed the Quadro4 XGL series of graphics solutions to push the state of the art for performance and features. They are designed to drive ultra high resolutions like 1280×1024 and higher. When testing, make sure you test at high resolutions. Always disable V-SYNC. V-sync is controlled separately for different APIs. Disabling V-sync is recommended because all professional workstation applications use double buffering to deliver high-quality images during dynamic graphics. When running benchmarks built on top of these applications, synchronizing swapping display buffers to the monitor vertical retrace can easily prevent the GPU from delivering its true performance. This is likely to be the case as GPUs become increasingly more powerful.
