This is probably very academic to those of you who are computer literate, I am not. Having said that please offer any advice in kindergarten language for this 68 year old duffer. Being a former helicopter combat aircrewman, back in the day of Nam, I very much enjoy the combat "shoot 'em up" type P/C games like Novalogics' Comanche 4. My problem is when I'm really into the game and I am "attacking" the "enemy". The game goes along fine but will suddenly crash, if I am firing the guns, they will keep firing uncommanded, I loose control of the game and it runs wildly until it eventually shuts itself down. On other games like EA's Battlefield 1942, the action is erratic at times and there is a lot of stop and go and hesitation or lag. My P/C, a Dell Dimension 4600 has their standard Intel Extreme Graphics 2 video card. My Grandson tells me that card is very inadequate and that is my problem. He tells me I need to upgrade to something like a 128MB DDR ATI Radeon 9800 Pro Graphics Card which costs about $200. Someone please interpret this for me and is my P/C whizz Grandson steering me on the right track? I have ordered that card from Dell, I hope I haven't wasted my money. Wanna kill these ads?
