I am getting acceptable frame rates in FSX (25-ish), mainly by completely turning off water, using simple clouds, turning traffic completely off, turning off auto-gen completely, and setting scenery complexity to "normal".While getting reasonable frame rates in the sim itself, I notice that using the spot plane view on instant replays is unwatchably jerky. The spot view while actually flying is just fine, and all of the other replay views are also fine.Is this just on my machine, or has anyone else noticed it?Also, I have a couple of landings in FSX that I posted online. You can see the type of frame rates I am getting with the type of scenery I am using.http://www.youtube.com/profile_videos?user=VegasRexI am running an AMD FX-55 at stock 2.6Ghz with dual 6800 Ultra video cards and 2 Gigs of Ram.

You aren't selecting the 'spot view' rather than the 'fixed spot view' are you? (there are two spot views and the unfixed one does jerk around a bit, play around with the S and A keys to get the fixed one).Fixed Spot view works okay for me. I did most of the scenery and cfg tweeks that are being posted apart from downloading the lower resolution land textures. My settings are all fairly high apart from water on 2x low, autogen scenery off (more through choice than necessity!). Road traffic is on pretty low now (as the stop-start motion of it is kind of annoying to look at) and I did have shipping on high but since it largely fails to materialise, I turned it off (didn't make much difference). However, special effects, anti aliasing, Anisotropic filtering, aircraft detail, clouds and detail sliders are all ticked or maxed to the right, plus I have Ultimate Traffic installed via renaming the traffic config file and copying it (and all the AI UT aircraft) over from FS9. with this I have commercial air traffic on 100 percent.All this is on one of my computers with an ATI PCI-X card, P4 3.2 processor and only 512 RAM! (although it is very fast, good quality RAM). Frame rates are at about 22 on average, which seems fairly smooth to me, and I largely fly from the virtual cockpit view too. But given what has been said about the shift Z FPS counter reading low in FSX, I'm not too surprised that it is smooth.

Yes, I am using the non-fixed spot as I like to rotate around the plane as it's landing, etc.I have done many of the tweaks as well, but I really need 25fps, or greater for the "true flying" experience.I like nice scenery as much as the next guy, and really wish I could run it, but I will sacrifice scenery for a realistic flight models. I can't come in high and hot on an approach and have the runway start jerking in front of me.The one thing I really like to do though, is analyze my landings after the fact, and in FS9 I always did this with the spot view on replay. It works fine in FSX is I watch from the control tower, but I like to be able to move around the plane and see how far I REALLY was off the center line. Sometimes the tower makes it look like I landed perfectly when I was 8 feet to the right of the center marker and I landed 200 yards past the touchdown marker. The rotating spot on my FSX is messed up as I have zoomed in, out, and all around, and it looks like the plane is having a seizure while the ground is in the throws of a 11.2 earthquake.I will mess around with some of the other views. I just got the sim last Friday and have already gotten 41 hours on it. Tweaking, tweaking, and more tweaking. As of now, the scenery is worse than FS9 due to my tweaks, but the flight modeling seems a but more realistic.I still REALLY wish they would not let me land in the grass next to the runway in a B737. I wish there was "anything other than wheels on runway" crash detection. That would up the realism another tick.I can still land on any flat area (including a satellite texturized shopping mall) without penalty. I even clipped the blast fence on on a low and slow landing, and there was no problem.There are probably tweaks out there somewhere to fix these things ...

Fair enough if you are on the 'moving' spot view.I certainly hear what you are saying with regard to checking out your landings on replay views, but at least FSX now actually reconfigures your aircraft in the replay to show how your flaps etc were at the time of the recording (it was really annoying when it didn't do that in earlier versions of FS on the replays).Personally, I quite like the fact that you can land in places other than the runways, and indeed it's now a vital feature with the glider more usable than ever in FSX, as it's fairly common practice to pick out a likely spot to land out when doing a cross country in a glider and the thermals run out. Although if you ever do this for real, be aware that coming down on the ninth fairway is a guaranteed way to upset golfers!If your B737 comes down on the grass, you can at least be honest with yourself and think: 'yup, that would have ripped the undercarriage off and we'd have slid along on our belly'. Not every off-runway airliner landing has resulted in total disater; my personal favourite being the SAS DC-9, in which the pilot skillfully flared into the treetops to cushion the wheels-up landing, continuing down through the trees to result in a slightly dented aeroplane, but only one serious casualty. Now that guy could fly.Hmmm... wonder if you can do that with autogen?Happy Landings

Are you flying with frame rates set to unlimited?If so, try with frame rates locked, and the instant replay may be smoother.

I have the FPS locked to 27.I used 30 in FS9 and could hold it most of the time.Locking 27 in FSX will usually give me 23-27 while landing in my preferred aircraft (B737) at my preferred airport ... KLAS. (assuming all of the goodies are turned off)
