For those having concerns over the hardware requirements, I'll just base my thoughts over the leaked alpha, the gameplay/fps rates could only be improved for the full game, but these are the average rates I scored (I'll upload my screenies later)
System 1 = Pentium 4 3.2GHZ p4, ABIT IC7 MAX3, 512MBPC3200CORSAIRXMS, 9800 PRO, Windows XP:
Non-Combat, standing still = 79FPS
Non-Combat, Moving = 50-69 FPS
Combat = Depending on the situation, (Level 1 - E3 Tech Demo)I had from anywhere 5fps to 63fps
System 2 = Athlon 64 FX-53SOCKET939, MSI K8T NEOII , 1GB MUSHKIN PC-3500, ATI RADEON X800 XT PE, Windows XP PRO
Non-Combat, standing still= My FPS monitor maxed at 99..
Non-combat, Moving - Anywhere from 82 to 99+...
Combat = 64 to 89fps
Once again, please don't flame. I full understand this is the alpha, but this should give somewhat of an idea how the game will perform on different hardware. I apologize for the numbers, I recorded the lowest number I saw and the highest number I saw, but of course with the full game it will be fully optimized and I believe a 3GHZ p4/64 3400+, 9700PRO-9800XT/5950 Ultra should run the game fine with all the bells and whistles turned on.
