For Kamael to have the highest settings you need
CPU: Pentium 4 2.4GHz (or better)
RAM: 1GB (Or higher...)
3D graphics card: GeForceFX 5700 (512 MB) (I self have 1650x PRO but i can play with max Settings)
Connection: Broadband Internet Connection
HDD Space: 15GB (Or higher...)
I think this you need to play Kamael normal and fast
