I would like to find out people's opinions on this matter before I install it. If you coulld go back and do it again would you still have installed it? No bashing please, just, "yes I would get it again" or "no, I don't think I would" and the reason for your answer. Thanks.:)

Yes. It's made FSX playable for me. That's the difference now. Totally smooth at high 20's fps. SP1 is a good thing right now, when most people's FSX addon collections are still quite small. Reinstall is not a headache... yet:-)

For the same reason that an insect flys towards a zapper, yes I would. Not the zapping bit, the curiousity bit. ;)Gary

Although I'm not sure in this hypothetical situation, I guess I wouldn't. Although SP1 certainly has cranked up my framerates a notch or two, they weren't too bad before the patch either - even to the extend that without looking at the counter I probably wouldn't notice the difference anyway: I had "frames to spare".There's not much "pro" SP1 for me then, and one very good argument "contra": I find the "popping" autogen that comes with SP1 mildly irritating. Not irritating enough to uninstall the whole thing, but sure irritating enought not to install it again... in the hypothetical world where we could do things over again and correct past mistakes.Geez, how busy I would be correcting the astonishing number of truly IMPORTANT mistakes that I made during 61 years of life (grin)!Be well.Jaap Verduijn.

Bloody Oath I would. It's luvly jubbly.:-)John

I downloaded it, spent 30 minutes installing it, when I loaded up the sim it didn't work. I spent 1 hour uninstalling FSX another 3 1/2 re-installing it and backing it up and an extra 45 minutes reinstalling my add-ons and when I finally loaded it up and started a flight I was getting 6.8 fps, IF I WAS LUCKY!:-grr Before SP1 I was regularly getting 14-15 fps. What did I do wrong??? Somebody please tell me I didn't waste over 5 hours on something I can't fix (short of spending 2 more hours re-installing FSX.):( By the way, Microsoft, next time please include a readme.

What were your FPS before SP1?Could you try SP1 with no add-ons?

Phil,Whilst your about I just wanted to thank you for the best flight sim, in my opinion, made to date. I now have 90% traffic both Commercial and GA (generated with TDBB). Normal Autogen and everything else except Bloom wound up or on. I am now achieving an average of about 40FPS peaking at 49FPS (I am locked at 51) at 1280 x 1024, no blurries, no perceivable stutters and I run 16QAA on my Nvidia 880 GTX video card. The best tuning for me was to set FSX CPU affinity to CPU1 (I have an AMD 6000) and all the other junk including FS addons such as Active Sky and my Trackir driver turned over to CPU0. I just completed a flight in my Real-Air SM 260 from Syracuse to Erie with RW weather on through ASV. It was just delightful (both the weather and the flight).I really didn't think that this sort of performance and visuals could be achieved with current equipment. Many other users aren't experiencing my joy, my gut feeling is that many of the performance issues expressed by users are being caused by disk head contention and interrupt queuing. As I have no intrumentation to check this it will have to remain a gut feeling. Thank you for the experience.John(PS Don't tell anybody but I never achieved these frame rates in FS9).

I have had very positive results with SP1... I give it a solid thumbs up!Bryan

Yes, personally, I am happy enough with SP1. I think, though, that you will have to decide for yourself. Answering these questions might help:How happy am I with FSX before SP1?Do I plan on buying software add-ons?How much time can I afford to spend on installation chores (At least an hour, likely an afternoon or two to do it right)?Am I willing to do Internet research to find out how to install SP1?Jeff ShylukAvsim Product Reviewer

Yes. Download it. I haven't seen any frame rate increase from it (still tweaking) but loading times are much improved.

I will try it without the add-ons. I tried it with the default JetRanger, 5 mile visibility and maximum cloud cover, and was getting 6-10 fps. Before SP1 I was getting 11.5-15 fps with the same weather and the same place. How do you install it? Maybe I didn't do it right?
