Framerate "hiccups"

[brokencircle19]

So, I just switched to the latest release from 1.65. On the older version of Oolite, everything ran smoothly without a problem.

With this new release, however, the framerate "hiccups." I say framrate, but really it seems to be the entire program. I will be flying along fine, and then suddenly everything freezes for half a second or so, then life goes on like nothing happened.

These mini-freezes range in frequency from one every five minutes to one every five seconds.

I've tried lowering the graphics settings and searching for CPU-eating processes, but no dice.

I'm running Oolite 1.73.4 on Ubuntu 9.10 Karmic.

Hi brokencircle, welcome to the forum! I'm not qualified to help you here, but don't worry – someone with more nous will be along shortly ... in the meantime it might help if you provide a list of the OXPs you're using, including where applicable the OXP version number. This might be being caused by a version of an OXP that works with 1.65 but needs updating for 1.73.

[Cmdr James]

is there anything interesting in the log file?

Hi brokencircle19, and welcome.

Also, it might be useful to know which Graphics card and driver you're using.

Old versions of Your Ad Here used to cause this frame rate micro freeze from 1.69 onwards until quite recently.

So a list of installed OXPs and versions would also be useful along with the other info already requested - and include your CPU and and amount of RAM in that too - it all helps!

Oh, and as others have said - welcome to the forums...

In general, the main cause of occasional short freezes is loading of ship models and textures. It should happen less now than in 1.65 - assuming the same OXPs are installed, and especially on multi-core systems – but it certainly hasn’t been eliminated.

Hmm...really, I haven't had that problem during flight for a looong time now. After jumping/launching, yes, when a massive amount of scripts is running, but not in flight. However my system surely won't count as normal and is far beyond what oolite requires to run nice - but then I also do use extremely many oxps.

There's one thing I could imagine to cause mini-freezes: If an oxp is causing an immense amount of log messages due to some bug/warning that's written again and again to the log, talk about several thousand lines per second.

True, checking the log for bigosity wouldn’t hurt.

[brokencircle19]

Hi everyone, sorry for the delay.

Here's a list of OXPs:

Anarchies 2.3
Aquatics 2.11
Assassins
Big Ships 1.02
Commies
Mild Audio
Random Hits 1.3.6
Black Monks (shady)

I have a dual-core gaming laptop, NVIDIA 9600m GS card.

Removal of all OXP's didn't seem to change anything.

I should note-- the hiccups are worse in certain systems. Isinor (G1) is the one which gives me the most trouble. But again, changing the graphics settings doesn't seem to affect anything either.

That's weird. If it weren't system dependent, I would expect CPU limitation now. However, systems affect the random generator seed, thus maybe those systems simply have more ships.

Oolite isn't that CPU demanding, though...do you have background processes running which consume much CPU power or very little RAM so that the system begins to swap?

I've tried hunting down any hungry background processes, but it would seem that there are none. The Oolite process itself snatches more CPU during a hiccup.

I've looked around the Linux forums for any hint of this being an Ubuntu thing, but it looks like this is unique to my 'puter.

I will attempt a clean install and see what happens.

I've had CPU usage ramp up briefly (and memory too) under both Ubuntu and XP, during "hiccups".

[brokencircle19]

Clean install didn't help, but I got a hold of last night's nightly build. Though the hiccups are still there, they seem to have decreased.
