Well, since I'm slowly starting to work on the engine's renderer, I wonder what kinds of graphics cards you people have. It wouldn't be of much use if the engine ran only on my hardware configuration
It is possible to write fallback shaders for some older cards or maybe some more complex system for detecting hardware capabilities like the one Startopia has, but it takes time, which can be spend on coding other things. It'd be nice to know that certain generations of graphic cards can be safely ruled out (without angering the players).
There is also a nice utility caled OpenGL Extension Viewer, which can be found at the following address
http://www.softpedia.com/get/Programming/Other-Programming-Files/OpenGL-Extension-Viewer.shtml. It lets you know of the features your card has and also can perform some simple benchmarks. Results can also be exported into an XML file, which you can mail me (you can use my sourceforge email address - just click the link in my sig, i'm the only developer so far). You don't have to do this, but it'll be very helpful (or you can post the name of your card here and I can look it up in some database).
By the way, Terra is being currently developed on my AMD Sempron 2600+, 1 GB RAM and GeForce 7600GS (full dx9/ogl2.0). And I hope to have some kind of alpha/pre-alpha demo by the end of summer
