The testing of this sound card consists of three parts: game tests, SpectraLAB tests and my subjective impressions about the card. The testbed was configured as follows:
- Intel Pentium III 1000MHz CPU;
- Chaintech 6ATA4 (VIA Apollo Pro133A) mainboard;
- 512MB PC133 SDRAM by Hyundai;
- ATI RADEON 9700 PRO graphics card;
- Quantum Fireball AS40 HDD;
- Creative PC-DVD Encore 12x DVD-ROM drive;
- Creative MegaWorks 510D, Inspire 6700 speaker systems;
- Windows XP Pro SP1.
Comanche 4 Demo
As we have mentioned above, the Revolution 7.1 driver features three-dimensional sound algorithms: Sensaura and SRS Circle Surround II. As is known these math1ematics-heavy algorithms can load the central processor greatly. This especially refers to sound cards that don’t have their own digital signal processor (DSP). So, the more complex the sound positioning algorithm is, the less CPU resources other parallel processes will have at their disposal. To feel the performance hit the system suffers when executing these algorithms, I ran a resources-hungry program, Comanche 4 Demo. Here are the results obtained:
Of course, with these not very high fsp rates the picture will freeze from time to time in the scenes with rich dynamics. However, I should definitely think of getting a faster CPU. For a more illustrative analysis take a look at the results shown by Revolution 7.1 in comparison with other modern sound cards:
As you see, the sound cards from Creative don’t worsen the overall system performance in this test, while sound cards that don’t have a DSP onboard perform less efficiently. What about other games?
