Mine's a recent(ish) mid spec machine.

Intel dual core jobby, can't remember the processor speed.
2gb ram
BFG nVidia GeForce 7900 GTX
Windoze XP

It plays Crysis quite well and Quake4 like the US's new super greased Mach7 warship bourne Hyper-cannon railgun thingy. http://www.theregister.co.uk/2008/01...rsonic_cannon/

Machine spec is largely irrelevant though saying as the stuff I develop tends to take a while to come to fruition, it'll be a baseline system a long time before my game's ready so I'm not really worried too much about any possible issues with GLScene's performance (not seen any myself), it's fast enough for me at the moment and I need ease of use over speed.
