Plan-G slows to a crawl during flights

[kossori]

I have the latest version installed. I load up a plan and connect to FSX. Both over the network or on the same computer, after 30-40 minutes, the program is very slow to respond to any interaction. opening task manager shows it using 450MB of ram. I do not know how to test for a memory leak. though before I connect to FSX, it uses less than 100MB. I have a fairly decent system and the program runs great while it's not connected to FSX. I am using WideFS to connect since I cannot keep a connection with simconnect.

Please let me know if there is any other information I can provide that would be helpful.

System Info:
Windows 7
Intel i7 3770k oc'ed at 4.5Ghz
8GB ddr3 2134
GTX690 video card.
2 SSD; 1 with windows, 1 only Flight Simulator and related software.(including Plan-G)

Do you have lots of AI traffic? Try turning the traffic display in Plan-G off (just a stab in the dark here - let me know if it makes a difference)

Hi Tim,

I have experienced something similar.  I have a very good system, together with a second PC (not so good!) on which I sometimes run PlanG.  On either PC, when PlanG is run alone (as in not connected to FSX) the program runs smoothly.  Maps are pannable easily, and the mouse cursor moves smoothly.  However, when connected to FSX, my PlanG runs like it is drunk, regardless of which PC it is run on.  It seems to slow down, smooth map panning is virtually impossible, and if you right click on an item of interest it takes sometimes up to 5 seconds for the menu to appear.

One practical implication of this is that it is almost impossible to tune a nav instrument using PlanG, as the map display often updates between right clicking and the menu displaying, resulting in the menu being displayed for the updated map location, and not where the cursor was when the right button was originally clicked.  To work around this I have found I have to anticipate how the map will update and right click at an offset position depending on the heading and speed of my aircraft, together with the map scale! 

If PlanG is run on my local FSX PC then it introduces very noticeable stutter to FSX, whereas if it is run on the networked PC it does not.  Consequently I tend to run it networked to eliminate unnecessary performance degradation on my FSX PC.

I must be honest, this was with build 46 and I have not yet had the opportunity to test with build 51 to see if this eliminates the problems.

Thanks

What do you have User aircraft refresh rate, traffic refresh rate, range etc set to?

The AI Traffic worked for the first flight( short flight) but almost immediately after starting the 2nd (longer) it slowed down. I think weather causing it. I am using Opus for weather. I'm not sure if it is doing something that Plan-G can't handle cause it seems to run ok using NWS weather.

This is what Task Manager shows after the 2nd flight.

What do you have User aircraft refresh rate, traffic refresh rate, range etc set to?

User refresh rate = 5s
Traffic refresh rate = 30s
Range = 100km
