Thanks to trying to get Vanguard running right I have now kicked my RAM up to 2GB which has made a huge difference to all around system performance as would be expected and also I have pulled my Soundblaster X-Fi Xtreme Audio and replaced it with a Soundblaster Audigy 2 ZS which even with it being an older card it blows the X-Fi out of the water. I strongly recomend anyone stay clear away from the X-Fi Xtreme Audio as it isn't true 5.1 and does not run EAX as it should nor does it have true hardware acceleration which puts a great strain on your CPU and game performance suffers for it greatly. Now I have got the audigy in place all my games run superb and Vanguard plays flawlessly after a few minor INI file tweaks and performance in my other games has also noticably increased which is always a great bonus.
