I should of made my post a bit more informed indeed (Apoligies).
I run it on a dual core m/c, XP SP2, ATI 1950 graphics 256 & 1 Gb mem. No probs with sliders up high. As to 500Gb H/D, where do you get that from?
What frames you getting from your system with full sliders? Also have you installed any addon aircraft or do you just fly the default microsoft AC?
Reason i ask is because my last machine had the same specs and i couldn't run fsx for more than 30mins without getting the dreaded '' Your computer is out of available memory message''
