Performance rate on 3D Engines' database

In short, a performance catagory would be at best usless, and at worst misleading.

Yes unfortunately you did. It's clear that you misunderstand me. It would certainly be nice if one could know how far you can push an engine, but this simply isn't something you can reduce to a simple scale suitable for a catagory in a table. You see, it depends highly on what you specifically do with it. For example, the scene graph I work with at my job is more than adequate with respect to the scenes we are rendering, but it is relatively slow at node traversal, so a scene with many nodes may render slowly even if there aren't any more triangles or objects. Quake 3 is extremely fast, but it's speed is dependent on you constructing a static scene with large rooms separated by small doorways to suit the portal rendering. These are just a couple of very simple examples. Do not misunderstand and think that you can special case these engines with a small note or somesuch.
The short of it all, is that while it may be nice in theory, it just isn't a realistic possibility.

OTOH, it would be possible for the engine authors themselves to add a note about specific aspects of the engine that was tested - for eg: "This engine was tested in a Quake 2 level with full dynamics and 100 3d sounds running at 100FPS on a so and so configurated system". That would serve this purpose better then a catagory for performance with bounded values. But that would not tell you if you could make Quake 3 with it...

In any case, maybe you are right, so it doesn't matter. I just though that I'd like to know if an engine is fast or not before I have to download it's SDK, which size usually is a lot of MBs, with my 56k connection and need to test to find out if I can use it for a complete game!
