CPU lag

[Pszczolek]

When I play my map, it doesn't leak memory. Latency is good, there are no lags, but sometimes in some moment game starts using 100% CPU , and FPS goes below 1. What can cause it? I use some spells which create a lot of units but they are leak-free and can lag just for a moment. PC on which I played is Duron 900, 512 RAM, GeForce MX 420. My main computer is much better, but I don't have internet connection yet on this PC.

-if you kill units (even invisible dummies!), their corpses can build up and cause lag until they finish decaying

-If you have infinite loops, or really long loops, etc, (among other things), you can overload your processor.

Creating mass effects can cause horrible leaks aswell.

As long as you destroy the effects and their points, you should have no problem with those.

Can it eventually lead to game crash? But I don't think there are infinite loops in map. What do you mean "really long loops"? Loops with lot of actions in them or with many cycles? Does orders or custom values of units leak processor after their death?

I don't use mass effects, rather mass of dummy units. But It doesn't leak after spell finishes. Creates some lag on PC I played, but not very much and only during spell effect.

Map really uses about 200MB RAM - it's normal in W3, after some time memory usage doesn't increase (much). As I said lags rather goes not from memory but CPU.

Really infinite Loops cause the game to crash.
And loops with alot of actions which do not run that much can lag and extreme long loops can lag even they got just a few actions. (for example some huge searching loops)

 

[PurplePoot]

Really long loops as in loops with tons of stuff to do that are run frequently.

And depending on the type of infinite loop, (only figurative ones crash it, not literal ones) you can get a crash.

And no, dead bodies would not cause a crash. (or shouldn't...)

Check the temperature of your CPU. if its above 40° C, then you'll need to cooldown your computer. Although mine runs good at 42° C, it sometimes automatically shuts down when it gets too hot. I'm guessing the breaking point is 50°C? Generally you want your CPU to run at ~35°C.

Set your game resolution lower; my fps drop from 50 to 20 when i set the resolution from standard 1024 x 768 x 16 to 1280 x 1024 x 32 resolution.

Disk Defragmenter? Virus Scan? Spyware Scan? Disk Cleanup? Turn off other programs?
Is your operating system vista? Vista usually drain a significant part of the CPU.

Maybe you should post your codes; sometimes leaks caused by GUI's BJ functions are not detected and, therefore, have not been removed.

Most periodic timer timeout duration should not be below 0.005 seconds (might be higher).
Issuing an order to a lot of unit at once causes lag.
