Help needed on Blinking scenery

[akka]

My fs9 suddenly goes wired on me. All the sceneries starting blinking like lights on a Christmas tree. The trees disappeared and reappeared again and the frame rate starts to decrease and sometimes pause for a second then starts again.

I have some many add on sceneries installed that I have no idea which one caused this problem. I have recently installed some sceneries from a flightsim.ru (mainly Russian airports like ULLI St Petersburg and UHHH etc) These run fine when I flew from them. I have uninstalled those but the problem still presist.

Any ideas anyone?

Possibly a background process kicking in and putting extra load on the CPU. Does it occur at regular intervals, all the time from start to stop, or just once during a flight?
Did it do this before installing the Russian scenery?

Are you running it on a dual-core system?

Thx for the quick reply. Yes I'm running a dual core system. AMD Sampron 3800+ 2.2 GHz with 4GB or DDR2-800 RAM 320GB SATA HD on board ATI graphics chip with 512 MB of RAM (shared) and it happened from start to finish and not just occassionally in a flight. My operating system is Windows XP Professional with SP3. I think my entire fs9 folder is something like 25GB. I have 250 aircrafts (half of which are AI aircrafts for the 20 or so world's airlines downloaded from teh word of AI) and 230 add on sceneries

I run into that on my system too, but not until I've been flying a while. I've found that if I set the processor affinity to just one core, the problem usually goes away. FS9 really wasn't designed with dual-core processors in mind.

There is also a patch from Microsoft for dual-core processors (which you should already have If you have SP3), and a dual core driver and optimizer from AMD. These three items SHOULD help with the problem.

You should be able to find what you need on this page:

Thx for the advice Groundbound1 and that is what I call real time response

[Groundbound1]

Hope it helps. I just looked at the page I linked to you, and there doesn't seem to be a Driver for the Sempron. At any rate, I'd try setting the affinity to one core first to see if that's where the problem originates.

How do you set the affinity to one?

[Groundbound1]

Well, this is where the fun begins. It isn't hard, but if this is the only thing that fixes the problem, you'll need to do it every time you start your sim. (Unless someone else know of a way to make it stay "fixed")

Here's what you do:

First, start your sim. You don't need to load a flight or anything, just so long as the program is running.

Then right click a blank spot on your task bar, and bring up your task manager.

Click on the "processes" tab, find "Fs9.exe" in the list and right click on it.

At the bottom of the menu that comes up, choose "Set Affinity". (NOT Set Priority, leave that one alone)

You should then see a new window that lists all available cores, in this case all should be grayed out except "CPU 0" and "CPU 1", which should both still be checked at this point.

Now all you have to do is uncheck one of them, click "OK", and the sim will then be running on that core only. (the remaining CPU that still has a check ).
Normally, you should assign the core with the least amount of processes to your sim, but if you aren't running too many programs in the background, it likely won't matter much which core you choose.

Close the task manager, and start flying. If all seems well, then I led you down the right path. If not, I may not be able to help you out.
