Thank you, both. Updated Wine (was on the 1.6 branch, still) but no luck.
The 'slow harddrive' aspect is probable. This is a somewhat oldish laptop with a replacement no-brand hard drive of mysterious features (it was cheap, which was important at the time when the original one died!). Terminal spits out number of error messages throughout.
err:d3d:context_create Failed to set pixel format 36 on device context 0x1005a.err:d3d:context_create Failed to set pixel format 44 on device context 0x1005c.err:d3d:context_choose_pixel_format Can't find a suitable iPixelFormat[i]And so on.[/i]
There's a new computer coming in, on the near horizon, that should definitely be fast and responsive enough. I am not the impatient type, so it's not much of a problem if that's what it is . (I bought this, and a few other games, irrespective of GOG's official Linux support being announced to happen at an unspecified time in the future. I can wait.)
