I bought Just Cause 2 via Steam and installed on Windows 7. My video card isn't great, but I could run the 3 test scenes at 30fps at 1280. When I played the game, it ended the first cut scene, I jumped out of the plane, it said loading, and it hung there forever. I restarted the game and the same thing happened.
I read that some other people have the same problem, too. Some suggested deleting the app files, which probably just resets the video setting. That didn't help. Suggestions?
Update: I checked the minimum requirements, and I believe my PC meets them all. I have an ATI Radeon HD 3650 card, and when I lower the resolution it does just fine (30fps) on the benchmarks.
