HG; I just went to look at my packaging for my card and it seems I misspoke (misstyped?). Mine is a PNY GTX260 core 216 with "only" 896MB of onboard memory. HSFX 4.1 here. So the problem could be either something to do with HSFX's version of the map, or not having that little bit more memory.
Sorry for almost hijacking the thread.
