Well, I bought CFS3. And just like you people, I was totally disappointed at first. Stutters and slow loading.
But when the next day came, I heard about the tweaks that can be made to improve the sim.
You can download a set of instructions from simviation. The instructions are simple and straight forward. As a result, I have managed to improve the performance very dramatically.
My specs:
Pentium 4 processor with 2.4ghz
512mb ram
GeForce 4 MX440 (Gateway) with 128mb
60gb Hard drive
a cd-rom that has the speed of the SR-71 Blackbird

Windows XP
There are some things that many people have to get use to. Change inevitable (the sims new game engine, etc.).
Stop talking negative about the warp option, alright guys.
In real life combat, you don't get warp drive and fly from London to Berlin in less than one minute. Yet nobody wants to fly from London to Berlin for hours at the speed of 250 mph (ww2 airspeed measurement) on a combat simulator. So I suggest that you drop the subject about the warp. I know that the warp sucks in CFS3, but the game engine is new and the warp has to operate differently. So get use to it. There, end of conversation about the warp option.
Now as for the campaign. To me, the campaign is GREAT (I don't know about you people). I say it's great because I make it great. Don't you see guys? Since the war is affected by you people, it's up to you people to make it fun.
It's possible that the campaign is boring because some people lose at first. As for me, my heritage is all about war. My dad, grandpa, all my uncles, etc. My battles in the sim are great because I'm used to the idea of conflict and I have studied a lot (in fact all) about WW2 (how it was fought, who fought in it, what military leaders were involved, etc.).
I don't want to start a flare up around here.
All I'm saying guys is that the quality of the sim is really (or just probably) based on the views of the user himself.
Don't expect all your favorate eggs to together on one basket. If that happed, then M$ would or will not be able to make a better sim.
There, end of my conversation.
