    NOTE: The 3DNow! Q2 Drivers only effect Quake 2 performance and do not help/hurt performance in any other games

    There is obviously a considerable improvement over the K6-2's performance under Quake 2 when using the 3DNow! Quake 2 Drivers provided by AMD.  These drivers should be making their public release some time in the next week.  The drivers are still not taking complete advantage of the K6-2's potential, and there is still room to improve on the performance end of things.   With Quake 2 as a working example, a bit of hard work can definitely pay off with the K6-2, all that is required is software support, and if the demand is there in the market, the software support will follow. 

    Older Glide games, that won't take advantage of the K6-2's 3DNow! Instructions perform just as poorly on a K6-2 as they would on an original K6, in comparison to a Pentium II.  It is doubtful that patches will be written for older games, so depending on what games you like to run the most you may be out of luck.  Even games that do take advantage of the DirectX 6 engine fall behind the Pentium II in terms of performance as can be seen by the Forsaken benchmarks (although they are all over 98 fps, which is beyond smooth).
