Well, in flight everything runs smooth. I just hate those stutters when taxiing and turning on the ground.Any tricks to reduce specifically ground stutters?

I have the same problem, and, like you, have not found the answer. Have tried turning off aircraft shadows, did not work. Also turned off the anti virus, that did nothing as well. Wondering if it might be the autogen somehow. I plan to keep testing, turning different things off one at a tme in the Display items. My machine should handle it. Have an AMD ASUS K8V SE Delux board with AMD Athlon 64 processor VIA K8T800, AMD 64 3200+ chip set, 1gb DDR3200 (400) ram, MSI Geforce FX5700 AGP 8X with 128mb. If I find any answer, will post back. Please do the same. And if anyone else has any ideas, please let us know. This is a real irritant, especially when flight is so smooth and stutter free.Regards,Paul

I suffered the same problems as you guys and fixed it by reducing AI traffic.Give that a go if you havent tried it yet...specially if your AI slider is at a high setting or maxed out.Also I noticed (at least for me) that stuttering occurs more while taxiing on add-on hi-detail airports.

Hi Nevin,Thanks for the input. However, I am using AI at 15%, and do all my flying out of the smaller US Regional Airports. Even there, with NO AI traffic to speak of, taxiing causes the same stutters as I get at KHOU, KOKC, KDAL and KMDW.Wil try it with AI at zero, see what happens.Regards,Paul

Paul - Yea you will have to juggle all the sliders and see what happens!Play with the demanding ones first: AI, cloud-draw distance, cloud %, mip map, render to texture, shadows etc etc.Hope you find a fix!!:)

Hi,You can also try to check in the FS9.cfg, that the "PanelAsTexture" header is set to =1. It should look like this "PanelAsTexture=1".This is if you have the stutters in the 2D panel mode ofcourse. ;-)Happy non FMC flying, Staffan AhlbergSweden/Stockholm/ESSAPMDG MD-11 Team - Beta testerhttp://www.scandicair.com/images/dc9_banner.jpg"I will come and cut your lawn for a high quality DC8-63 system"[/color]My specs are:Dell Dimension 4600 P4/3.0 Ghz1024 Mb DDR333 Dual channel memory (2x256,1x512)128 Mb ATI Radeon 9800 ProOmega 2590DirectX 9.0cW XP Home with SP1E171FPb Flat panel monitor 17"240Gb (2x120) 7200rpm HD

I have read here and elsewhere that having ground bumps enabled with FFB controllers has caused this type of problem-John

Thanks for all the ideas,AI Trafiic isn't it for me, as I have it a 0%.Before I had to reinstall FS, I had PanelAsTexture=1, but I haven't changed that yet. Thanks for the reminder!Will let you know if I see a measurable difference in smoothness.

Thanks Staffan,Wil give that a try. I just checked, it is set to "=0" as one of the fixes I put in some time ago to improve frame rates with my old computer. When I transferred everything over to the new one, that was overlooked and left as is. Regards,Paul

Hi John,Thanks for the suggesiton. Unfortunately, I do not use a FFB controller. But do apprciate you taking the time to help.Regards,Paul

Try turning off all unneeded processes that are running in the background. Go to http://www.blackviper.com/Rex

I have read of this panelastexture tweak before, but have never found it in my fs9.cfg. Where is this phantom tweak located? Or do just some fs9.cfg's have it depending on your video card. I'd like to try it, that is, if I ever find it.

[DISPLAY.Device.RADEON 9700 PRO (Omega 2.5.97a).0]Mode=1024x768x32PanelAsTexture=1 <---------The tweak goes hereor use PanelAsTexture=0 though that really take a hit in the FPS department on my videocard.

Funny you should ask about the display "stutters". Just today I spent about 2 hours flying and testing. Here's what I found:Although mine were most noticable in the air during turns, they were just as bad on the ground. A better description is a slight "pause" sometimes longer than a "stutter".I tried all one at a time:1. Turned OFF AI traffic all together. Didn't fix the pauses. I'll get to this one later. So turned AI back on 100%.2. Turned elevation complexity to 0%. That didn't work. Turned it back to 100%.3. Turned textures to lowest (on same screen as elevation complexity, autogen setting, scenery complexity, etc.). That didn't work PLUS the ground textures looked HORRIBLE! Turned back to full.4. Turned off autogen. No go- turned back to max.5. Turned scenery complexity to nill. Nope- back to complex/full.6. Building shadows was untouched, always had those off.7. Closed Active sky (AS 2004). No difference at all. In fact I was surprised that frame rate was little effected by AS 2004. And happy :)7. Went to the last "tab" in settings and I had this one slider to the maximum (massive?)- I think its called "scenery texture size" and it's on the same screen as the video card, mip map settings, etc. (the very bottom slider). Anyhow, moved that ALL the way to minimum, and whoalla! No more pauses. Then I moved it one notch at a time and it is now sitting at "medium" and the building textures look "okay" but not as good as they did when it was at "massive" setting. BUT no more pauses.I then tested a little more to get my frame rates a bit better. Noticed by turning off AI really helped, along with taking autogen out all together. But that's only in serious cases.I know this issue has been covered thousands of times and someone probably already has this "tweak" on the board, so I apologize if I am being redundant.

I'm willing to bet that you have Force Feeback checked ON.With that on, Even I get stutters with my P4 3.8 and Radeon X800XT Card.Try turning that off, and watch a world of improvement.
