From what I've seen, the minimum requirments to run MSTS are a bit unrealistic. Just for the sake of knowing what each of us are dealing with, it would be good to know what everybody has in the way of hardware. For example, I've got the following on my computer:
P4/1.6 gHz, 512 meg, 40 gig HD., 17" flat panel LCD display, Win XP-pro, 64 meg video memory (dedicated) and Altec speakers with sub-woofer.
They claim you can run with a P2/350 MHz and 64 meg of memory. and 8 meg of video memory
Now, running with what I have,I found it slow loading and have encountered screens that flicker. I ran the tutorials without any problems, and took a demo run, but the second time I got in the cab and ran the train, the program froze up. I guess it could be my machine and what I'm also running in the background, but I guess I'm asking if anyone else is seeing the same things? I'm wondering if I need to run it in possibly the Win 98 compatible mode.
I don't think it's going to have a real steep learning curve once you get familiar with the controls, but I also think it might become adictive really easy. Something neat to do when you just don't feel like doing anything else.
