Ok , sry for my late reply, but I am sick at home and after 2 nights without sleep I managed to have a nap.
Anyway, my system is the following:
Intel E6750
4 GB DDR2 RAM 800MHz (normal latency, Kingmax modules)
Mainboard Gigabyte EP43-DS3L
Videocard ZOTAC 8800GT AMP!
Hmmmm, about the native resolution of my screens, I donno what to tell you, they are 2 Proview 17" CRT, even though they are Proview, they are different models ( as for dotpitch).
EDIT: I normally play LOCKON FC V1.12a, I'm working on Windows Vista Ultimate w/SP1, and as Video drivers I have the latest 180.43 for Vista. I have FC graphics normally set on full, except shadows and distance, so I play it at a res. of 1024 x 768. I think that if I leave the same settings, use it on 2 screens and use a Res. of 1280 x 1024 it will freeze up.
