Just installed and used G3 for an hour or so. No doubt about it...this sim will need a high-end video card/fast machine to run well. I had to turn-off several graphics options, and tweak to get the frame rate acceptable on my machine. 64-bit Athlon 64 3200+ with an nVidia FX5200 128MB graphics card, which, in this day and age (got computer almost a year ago) is now a "bottom-end" card supplied with lowend machines....this card is now about 49.00 bucks.

I've determined I won't be satisfied with the 6600GT card (mid-range) I was looking at, and now will only be satisfied with the 6800GT, or equivalent, basically, most top-tier cards costing from 350.00 to 450.00 bucks or so.

The graphics engine this sim requires, to run with all the wondrous graphics at high-resolution enabled, will have to be costly.

You may disable lots of graphics intense objects/scenery, reduce resolution and such, and get this sim to "run" on slower machines, but getting a taste of what this sim does with all graphics enabled, has prompted me to get a decent graphics card to use G3 to its fullest.

I would buy G3 again, if given the choice.
