It also happens with FSDT's KDFW, where they mention in the users manual to turn off transparency AA for that scenery. Prior to reading it in their manual I was getting some really jerky taxing motion when at that airport. However, once I turned transparency AA off KDFW was smooth as silk. Like the OP mentioned, I also get a little tree shimmer that I never noticed prior to turning it off. I can live with it but the trees looked a lot better with it on.

Hmmm... interesting, the tests I did were at FSDT Kennedy! thanks for pointing that out. Didn't know they recommended transparency AA off to solve it.

Confirmed, ******* and I always asked myself where this thing comes from as it happens at a very important point of a flight.

Notice the comment by another poster that FSDT recommends it off. So this is probably FSDT specific.

I had this "final stutter" at quite a few airports too, not always and not everywhere. I'm using transparency AA and would really miss it if it was set to "none". I have to watch this more closely to get a picture where and when this occurs but maybe the FSDT devs can say something about their recommendation to turn it of at their sceneries. Either they go for a general off for overall performance reasons or they know what actually triggers this final stutter just before touchdownThis currently is a trade-off for me: get stutters at the approach sometimes and somewhere or always look at e. g. shimmering gauges. The sad fact is that you really find the shimmering annoying since you saw what transparency AA can make of it. Sharp and nice to look at and read steam gauges and non-annoying lines at GPS and primary flight displaysTransparency AA with a "sparse grid" setting really enhances image quality there

Hi *******.Just to be clear I think that turning of transparency AA only applies to KDFW due to the way they used shaders for the airport and its ground textures, and most likely for the upcomming KLAX since they plan on using these advanced shader techniques for it as well. I dont think that the transparency AA issue effects the older FSDT airports like ORD, JFK, FLL, etc. I could be wrong though and you might want to check with Umberto over there to be sure, but I think this is the case.

Another interesting point... Like I said, if I disable 'shaders' in FSX, I don't get this 'final stutter' 10ft before touchdown so, it is 'definitely' something 'used' in .mdl files. I will ask Umberto

I have found 8sQ to be the best shimmer reducer.LOD Bias Clamp.

I've done this but I get the feeling my card/system isn't powerful enough. It definitely helped with the trees and also shimmering on my Lancair panel though...I'm now getting mega stutters and a large variable frame rate, even with fps locked at 30. It's pretty much unflyable due to stutters... I'll have to stick with 8xS.p.s. and HECK NO to transparency AA L O L!!!! I thought 8xSQ was stuttery hahah :(

The added FSX.cfg lines of vsynce, mipbias just dont work as well compared to the driver, ATI cards asside of course.

Ill try them at the driver level, thanks for the info :(

To see the improvments just make sure you dont forget you'll need decent res like 1920x1200, at the driver set texture filtering set at high quality and negative mipbias=allow, in FSX.cfg manually change LOD to 6.5 or more if that is your liking, remember its all about balance >smoothflight+IQ&performance/your system and FSX+addons and config.

That setting is card specific. When I had a gtx285 I couldn't run 8sQ either. Now I can use 32aa + Taa without a performance hit.

I think there's possibly some unrealistic expectations with regard to distant object shimmering. There is ALWAYS going to be some amount of it - that's just how 3D graphics and the pixels on your monitor work.An AA mode like 8xS or 8xSQ and the transparency AA feature do a lot to mitigate it, but even if you had 1000X AA there's still always going to be some level of aliasing, however small. It can never be absolutely perfect in any game, FS included.I just ordered one of the brand new GTX570s last night - this is a big upgrade for me and I intend to mess around with all the newer AA modes that only exist on the 4xx and 5xx series cards to see if I can get this kind of stuff looking any better. I'll update my post in the PMDG forum about Nvidia settings if I find anything that looks better than the long-standing 8xS stuff.

What I find most frustrating is the shimmering of the water at medium distances. I've tried every conceivable setting in both the FSX.cfg file and Nvidia Inspector and haven't really been able to clear it up enough where it's not distracting. (specifically when looking in the direction of the sun's reflection on the water.)I can agree with those that say that's been more pronounced with the newer drivers released. I didn't have this with the older (197-ish) drivers. But with Bojote's tweaks and the positive impact that they've provided, I've decided to compromise between getting the most out of the sim and suffering with some shimmering effect.

Go to the Ground Environment X forum at Simforums.com and read Nick's tuning guide.I had 8800GT and using this guide got rid of the shimmers and improved everything else.Nick is the MAN.Unfortunatly my 8800 GT card just took a dump.I am waiting on a Geforce 260GTX that Nick recommended for my 4 year old system.Ron

My system is configured per that guide... my inspector settings are setup per the guide as well, but I have AA turned down to 4x at the moment.

Check which driver you have.I upgraded and I should not have.Check Nick's advice on using Nhancer or Nspector ( not sure of the spelling I have had my medicinal beers).There is a differance.

I had the shimmering effect on fences surrounding an airport and tree shimmering I noticed on the ground near airports. I was told by the techs over at Nvidia to Clamp the Texture filtering - Negative LOD bias setting in the display drivers. The default is Allow. When I changed the setting to Clamp, the shimmering went away.Best regards,Jim

There may be some truth to this theory... I'm on the "latest" driver - which we all know isn't exactly optimized for the older cards. People says the latest driver is best but I tend to disagree. Honestly, I also think inspector isn't working as well as nHancer did when I was on my Vista build. What I may do is revert back to a 19x driver and try that... or I'll take recommendations for a 8800gt!
