GPU 3D heeft een artikeltje neer gekieperd waarin ze de features van S3TC en 3dfx FXT1 vergelijken. Hier een stukje uit de conclusie:
Though these two compressions do have their differences, the end result is the same, an equivalent picture of smaller size, allowing developers to utilize larger textures and to devote precious bandwidth to other places. The 10,000 dollar question, which is better? That's a toss up. The FXT1 relies on complex algorithms and coding to deliver a better looking image, however common sense dictates that this may be slower than the S3TC. Is the greater complexity , free source, and greater flexibility enough to supercede S3TC, time will tell.
