Specs for Saga are:
Core 2 Duo 1.8 GHz, 1 GB RAM, graphic card with 256 MB (GeForce 7600 or better), Windows XP/Vista/7
Many gamers already said - Ego Draconis (besides German version) is terrible optimized and stuttering appears even at strong PC's with 4 GB of RAM. This is the engine fault.
Also for XP 2GB of RAM is more than enough (although for Vista or 7 4GB is recommended).
