Hello, forum.
I downloaded Universe Sandbox from Steam a day or two ago, and I'm very impressed with it.
Unfortunately, I only get to play with it for a few minutes at a time, because I'm experiencing a lot of crashes. Also unfortunately, these aren't crash-to-desktop faults where I can reload the program and start again; instead they're dead stops, requiring a reboot. I suspect they may be related to my video card, which is an admittedly old ATI Radeon HD4800. (I should mention at this point that whilst upgrading my card would be nice, it's not financially possible at the moment.) Since upgrading to Windows 7, I believe the card's running on a generic driver, but I've had similar problems with other programs on XP for some time.
Several fairly recent games runs all right - so far I've had no problems with Shogun 2, for example, but there seems to be something about US that my current setup doesn't like. Has anyone else experienced any problems with US using ATI cards, and are there any GFX settings I might tweak? (For that matter, before I download any proprietary drivers, can anyone recommend a version that's generally stable?)
