Hmmm
Didn't have any problem like that. I didn't have SP2 installed in my XP Pro after all the criticisms I've read about it and I always thought it would reduce my FR in FS2004.
Far from it. Installed it for FSX and FS2004 runs smoothly and at least as fast as before. Could even be a bit quicker...
Yes Sir!
Nothing wrong with SP2... 99% of the SP2 problems stem from AV being run while the update is being applied, an overclocked system which SOME PEOPLE think they can run while installing O/S and updates like that - OR - they did not reboot SEVERAL times after running the SP2 update and it was buggered because they went directly to making settings changes and cleaning out temp files before it had the chance to finish installing.
SP2 introduces a few new services and resets a few things that need to be turned off to recover the memory and CPU cycles the items suck, and that is why low memory systems may see a performance difference however once the junk has ben shut down, SP2 provides a FASTER platform for gaming.
Running the DX9 web update once every 3 months is also important. Many do not realize their DX9 is not up to date and it will install updated files based on finding SP2!
There is nothing wrong with SP2.
