Suspected Memory Leaks - 6/25/2014 2:16:12 PM

I have observed in large scenarios (> 1000 AU), that over time game performance diminishes. I tend to run games a long time (>4 hours). Also, when one saves such a large-long game, quits the application, and then restarts the application the performance will dramatically improve.

From the outside looking in, such behavior is indicative of a memory leak with the application.

I do not have the tools or access to evaluate this for you. However, just a heads up that I suspect you have garbage building up in memory as a large scenario progresses.

Feltan

Agree Feltan have the same prob on larger scenarios

Thanks guys. If you can post up the scenarios under which you are observing this issue it would be great. (I suspect this result from actions that may be scenario-specific, e.g. excessive pathfinding). We can then investigate this as time and resources allow.

Thanks!

Sunburn,

Attached per your request. However, my experience/observation is that any large scenario run for a long time will exhibit this behavior.

I hadn't thought about path finding. The events I have noticed were after large engagements, and thought perhaps the app was not cleaning up destroyed units memory allocation -- especially guided missiles. But that is just a hunch.

I am not sure what language you code this game with, but if you don't have auto clean-up (like in C or C++) you are bound to get some leakage. Even if you do have auto cleaning, it happens with larger programs all the time, and it is a PITA to find an fix.

In the attached scenario, you will need to run/play it for around 4-6 hours before you note that performance is bringing to its knees. Save, restart the app and load the save. Everything is perky again.

Feltan
