Acceleration problem with flashing flight deck

Recommended Posts

Hi All,I just installed Acceleration and noticed a very annoying problem. The flight deck in front of me is flashing and shaking most of the time, regardless of where I am at - in the cockpit or viewing externally. This is happening when F-18 is parked.I have tried different GeForce drivers - 169.21, 169.44(beta), and 174.74(beta), and the problem persists. I searched this forum and didn't find any complaint. Am I the only one?Thanks,JohnWindows XP SP3, Intel E8400@3600Mhz, 4GB RAM, 8800GT 512MB.

I am on Windows XP SP3, so I guess I am using DX9?

>other aircraft?So far I have only run the two missions: "Carrier Training" and "Carrier Practive". Both missions exhibit the problem.>>paused or unpaused?>unpaused. I didn't try pausing.>sim rate at normal or accelerated?normal.>>mesh resolution at 10m or higher/lower?Where can I see the mesh resolution?John

it would be worth seeing if other aircraft exhibit this problem.Did you install anything that might have changed the aircraft.cfg and contact points?See the Settings dialog. it is worth playing with the settings and see if this behavior changes.

It sounds like you have a problem with the flight deck and not with Acceleration. My FA18 is perfect with absolutely no hint of flashing inside or outside. I have never heard of this problem with Acceleration for non-DX10 users. Sometimes the outside strobes will bleed through if you're using third party lighting and it will appear like there's flashing inside the aircraft and, of course, you'll see normal flashing on the outside. Did you turn off the "Display Flying Tips" in the Realism settings? This has been known to cause some white flashing with or without Acceleration installed. Are all the FSX sliders set to max (scenery/AI/aircraft)? Try lowering them and see if this fixes the problem as you may have rendering problems with your settings set to max. What is the flight deck? Is it a third party aircraft carrier or one of the defaults? Maybe you could tell us exactly where this occurs so others can try the exact same location and see if it occurs on their system (or does it occur everywhere, even at airport runways/taxiways). IMHO you should not be seeing "flashing and shaking most of the time" so if none of the above suggestions do not fix it, you have something wrong with your computer system or video card.Jim

Phil,Sorry I am new to FSX/Acceleration. How do I choose a different aircraft and have it parked on the carrier? I thought I can only access the carrier through the canned F-18 missions.John

Interesting. The problem goes away if I lower the Settings | Graphics | Target frame rate below 55. Increasing the target frame rate makes the problem worse. Every part of the carrier is vibrating to different degrees. And it only happens to the carrier. The F18 and scene don't have that problem.I still have no clue what "Target Frame Rate" means. I thought I could get the highest possible frame rate if I set it to Unlimited.Thanks for all replies.John

John,Set your target frame rate to 25 fps or something like that. If I set target frame rate to unlimited on my pc with my display settings I get a lot of stutters and graphics errors.Ulf BCore2Duo X6800 3.3GHz4GB RAM Corsair XMS2-8500C5BFG 8800GTX, Creative SB X-FiFSX Acc/SP2, Vista 32

You're probably in for a long hard slog with that video card.Search these forums for people who have display problems in DX10 games like FSX and you will find that in virtually every one of the posts, the person having the problem is the owner of an nVidia GeForce 8800. They never seem to get solved, and a new one pops up every day it seems.If you are really into simming, do yourself a favor right now and just get a different video card. Ask around, I'm sure folks will give you some recommendations.I use the nVidia GeForce 7950 and have been happy with it. It's a DX9c card, so if you're married to Aero, won't help you much.

The symptom you describe is likely a video driver issue. I've had tons of problems with the 8800 drivers and it took four months of tweaking on my end to get it just right, including a few times wanting to yank the card out and throw it through the window.I found that not all drivers are equal, and fixes in a new release break a fix in an older release. Because no two configurations are the same, my suggestion is to remove the drivers using drive cleaner pro (freeware version), and re-install. I had good luck with the September 2007 driver release with FSX, and better luck with the beta that came out in february 2008. Odd things happen when I don't use driver cleaner, so perhaps it's a matter of deleting your current driver, and re-installing them.Hope this helps, and good luck. My next card will not start with N.Etienne

>Set your target frame rate to 25 fps or something like that.Wouldn't that limit my frame rate to 25 fps only? And human eyes can sense up to 30 fps.John

Since I can easily get around the problem by lowering my target frame rate, I am happy now. Other than that I don't have any issue with my 8800GT. Maybe in a couple years I can afford to upgrade my PC again. But then again FS11 may be out by then and require future hardware. :-)John

You would make a great politician with that statement as it's hard to disprove and it sounds like you're on top of everything, the expert. Maybe you are but I have two 8800GTX's and never had a problem other than the DX10 display problems everyone is having no matter what DX10 compatible card people are using. As you should know, the DX10 Preview video problems are based on display driver problems from ATI and NVIDIA and FSX and the 8800's work great w/o DX10 turned on. Actually they work great even with DX10 Preview turned on except for a few display anomalies that Microsoft says can be fixed by video card drivers. ATI and NVIDIA may eventually fix their drivers to display DX10 enabled runways properly (one fix) but I'm not holding my breath. I just hope Microsoft eliminates DX10 for those areas that cannot be rendered properly by any video card manufacturer in the future version of MSFS. In other words, why develop something that cannot be shown properly? I also understand the DX10 problems still occur with the 9000 series cards. You comment does not support the facts...Best regards,Jim

Jim,I have no dog in the fight and certainly no expert.I just read every single post on AVSIM, and noticed a pattern, which I described for the OP with the issue. It's not difficult at all to "prove." Search the forum for display issues and look at people's signatures. Almost all of them have the nVidia 8800. I've come to the conclusion it's a crap shoot of a card.In point of fact, you state the problem in your response:"... I have two 8800GTX's and never had a problem other than the DX10 display problems everyone is having no matter what DX10 compatible card people are using."The nVidia 8800 costs DOUBLE because nVidia alleges it can display DX10. It cannot. You state so yourself in your response. That is the problem the OP has, and the reason he has it is because he is using the nVidia GeForce 8800. He was ripped off because he paid extra for DX10 and didn't get it. I wouldn't recommend it to anyone - but that's just my opinion. Your mileage may vary.I'm not trying to bash nVidia. I have their GeForce 7950 in my computer and recommend it to anyone. It claims to be able to display DX9c technology. It does so. No problem. I was not ripped off.But lots of people with the 8800 seem to have been.

"That is the problem the OP has, and the reason he has it is because he is using the nVidia GeForce 8800. He was ripped off because he paid extra for DX10 and didn't get it." Kevin,The OP is using Windows XP, SP3 - check his signature. Therefore he didn't get ripped off and he doesn't have DX10. He cannot use DX10 Preview. He's using the old technology just like you!Sometime Google the 8800GTX and read some reviews. You'll find the card is one of the best cards currently on the market. Now if Nvidia and ATI/AMD could come up with some decent drivers for DX10 in FSX...Ciao,Jim

I've had this problem as well, but it goes away when I am hitched to the catapult ready to hit the launch trigger. Wierd. I thought it was the triple-head to go set up I've got - but now I think it has to do with the carrier moving. Also, why on earth did MS put hand rails on the carriers? Sucks up CPU power to draw them = and they don't exist on carriers except in port (very temporary lines and poles). Didn't anyone watch Top Gun? See any handrails? Colin in Portland

That works for me.Regards,John
