Hi,I've been running FSX SP2 with no issues. I recently did a full clean install having built a new computer (thanks to Ryan’s advice on this forum) and have all add-ons fully installed. Has anyone had any issues upgrading to FSX Acceleration, has it caused any problems? I don't want to try it and find I then have a multitude of issues, forcing an unnecessary re-install.

I just upgraded from SP2 to Acceleration without deinstalling anything despite the SP2 which you have do remove before you install the Acceleration Pack.I upgraded because I bought the A2A B377 and I don't have problems with anything so far.GreetingsStefan Rakel

Thanks for the info. I remember reading, probably a couple of years ago, that some add-ons would not run on it.

Is there a need to upgrade to Acceleration? I have only had sp2 for years. Will we need Acceleration for NGX?Thanks,

To answer your questions.Matus-I have been running Acceleration for many years on a variety of systems. It is a wonderful upgrade from the Service packs if you have the money. I assume your aware of what the main contents are and all that stuff. The missions and aircraft included are in my opinion a little bit nicer than your normal default aircraft and missions. The F-18 is by far the best modeled in the pack witch still lacks some features but is very fun to fly. The missions are more diverse and exciting. I haven't noticed any big glitches or crashes affiliated with the Acceleration pack. I recommend it.toothjockey-It is very likely you will need either service pack 2 installed or have the Acceleration pack installed. This is standard requirement for most addon aircraft and shouldn't be any different with the NGX. However I recommend Acceleration, i'm positive Service Pack 2 will be sufficient. Also it wouldn't hurt to have Ryan's computer.

For the NGX you probably won't need it because the default FSX already supports jet-engines, what's new with the Accelerationpack is the support for Turbochargers and that stuff, that's why it is needed for the mentioned Aircraft.To be honest, other than that now I can take full advantage of the A2A Aircraft I think it is a waste of money. The Aircrafts don't statisfy my want for realistic deep simulation. The scenery is nice but not the places I personally fly to and I never fly missions.GreetingsStefan Rakel

There is an add-on that I purchased without noticing it required Acceleration. It only costs £12, so that's not an issue, I just didn't want to create issues on my nice clean install ;) Thanks for all your input, I think I will purchase it.

If i remember correctly the LevelD 767 has some issues with the acceleration pack.The engines won't start correctly and the plane jumps after pushback causing the FMC to reset all data.But i think they have a work around since a couple of weeks. Just check out the forum if you've got this wonderful aircraft.

Yes I have the Level-D 767. It was probably on their forum that I read about the issues with FSX Accel. I'm working my way through my add-ons to check if there are any issues, but so far all are ok or have a fix. The only issue I have seen is the "Living World Settings in LWcfg.xml are invalid. Delete LWcfg from your hidden user profile directory." error. I will install the Acceleration and see what happens. I have already cloned the drive in case of any issues.

You do not need Acceleration to run the NGX - it needs SP2 *or* Acceleration.
