Hello everyone,After much tweaking of both FS and my system, I thought I had more or less dealt with the odd stutters. However, recently they popped up again at a particular scenery location where I never had any problems before, i.e. Edinburgh Xtreme (UK2000). Typically the stutters occur at predictable moments: About halfway during the turn after pushback (from any gate), while turning onto the runway (both ends) and while crossing the threshold during landings (both ends). I didn’t change anything at this airport (no AES) and I’m not inclined to think that the problem has anything to do with the (excellent) scenery itself. Nevertheless I tried a reinstall but to no avail. I’m aware that this is a difficult matter for providing help, but there may be someone in the community who has an idea as to how to resolve this little, but annoying issue. Any thoughts about where ‘to dig’ would be very much appreciated.Kind regards,René

Hi!By "stutters" I presume you mean that the FPS slows down to the point where FS9 becomes a slideshow? I sometimes find this happens with resource intensive scenery particularly if combined with a relatively resource intensive aircraft when turning a corner, especially when I am in spot plane view. I think it might be due to a huge increase in demand on the video card when the image has to pan through very detailed scenery in a short period of time. I might be wrong about this and I don't quite know what to do about it! Perhaps someone more knowledgeable on the subject might be able to enlighten us or maybe the lack of replies means that nobody knows the answer!Bill

I would experiment by turning off AI traffic. This would prove one way or another whether you have excessive AI traffic demands - perhaps aircraft not designed for AI or ones with non-DXT3 textures.A hiccup just before touchdown is usually indication of a much-too-large file containing the touchdown sound having to load. You may wish to experiment flying with a default aircraft to see if you get the same.John

Could be your runway textures. You could try changing the runways, and taxiways. I've had stutter problems with certain pavements.

Hello,Thank you very much indeed for your replies! I'm going to check out your suggestions. It had already crossed my mind that I would have to look into the settings of the videocard, because there I changed a few things recently. For the record I should add that I flew into this particular airport yesterday with a QW B757 (retro) and did not encounter any problem whatsoever! Pushback, taxi and departure with this aircraft were also flawless. The problem funny enough occurs with the Wlico Airbus :(, which I've always regarded as less complicated than the QW aircraft.Kind regards and thanks again for your help.René

For future reference: Source of the mishap turned out to be a setting of the graphics card, i.e. the number of prerendered frames. After lowering this setting from 6 to 3 the problem disappeared. So I guess it's something along the lines which Bill described. Remaining questions: Why was only this particular airport affected and why was a rather complicated aircraft not susceptible, whereas a 'simpler' one was? This belongs to the enigma's of FS, I presume :( .Regards,René

Just out of interest, René, which graphics card setting allows the prerendered frames to be adjusted as it doesn't sound familiar to me?RegardsGary

Hello Gary,First I should explain that I have an nVidia 7900 GS with 256 Mb (Yes I know my system is aging, but it still serves me well :( ). In the driver's control panel is an FS9 profile, which I imported from somewhere, or created myself, can't remember. Anyway, in that profile is a line, after the Anisotropic flitering, AA, etc., with the title 'Maximum prerendered frames'. The default setting is 3, but since the explanation says that increasing this figure may lead to smoother performance with some games at lower FPS, I've set the value to 6 a few weeks ago. As it turns out, this can also have adverse effects, but it may well be that I understood the explanation wrongly and that 'they' mean increasing it to a value higher than 0 :( . Probably it all depends on the components of the overall system, and for my humble one (AMD Athlon 3200+, 2 GB RAM and 256 Mb on the card) a setting of 6 was apparently a bit too high (using REX, GE PRO, demanding aircraft and demanding scenery). Hope to have informed you sufficiently.Kind regards,René
