I have descided to go back to FS2004 after hearing alot of the hoo haa about FSX not being able to run well on current machines. My old computer which I no longer have, was a P4 2.4ghz with 512mb of RAM. I am currently thinking of buying something that is at least equivalent to a P4 3ghz with 1mb RAM. However I have read elsewhere and on this forum somewhere that Fs2004 is not optimized for dual core operatiuon and that it will run faster on a P4 3ghz single core machine than a 2offghz dual core setup. Is this true?
Would it be better to buy a Celeron at 3+ghz and lots of ram than a low-end dual core set up also with lots of RAM to get a smooth (15-20 fps) performance in FS2004? I am aiming to use some freeware scenary airport addones, dense AFCAD and the odd bit of high-tech planes such as PMDG's 747.
