Severe lag

[Phantom Hoover]

At times the game slows to such an extent that it is virtually impossible to aim. This tends to happen when there are a large number of ships in a fight, but also when there is a long range carrier in the area. Any ideas?

System specs? First lines of a Latest.log with the description of the graphics subsystem and list of OXPs running?

[JazHaz]

Yes I get this too. I find that using Game Booster helps a lot!

Sorry, I always forget logs.

It's worth to try it without Galactic Navy. It's quite cool, but slows everything down and needs a complete overhaul.

It's worth to try it without Galactic Navy. It's quite cool, but slows everything down and needs a complete overhaul.

This is the only one in the list that might give problems. I also have it normally un-installed because of its performance hit. e.g. the 5 ships at the witchpoint of each setcom systems do together 40 scans for offenders every second. Normal in game police do one scan every 10 seconds so it would need 400 normal police to to this amount of scanning.
And the same happens near the setcom station itself. Effect is of course that reaction on offenders is now fast, but at the cost of performance.
Similar things happen throughout the whole oxp. It is designed to work optimal for itself, not to work well with other oxp's.

One other object that slows down performance is the constore near the witchpoints. Calculating those shaders take also noticeable time on my system.

One other performance problem I sometimes have is that steering get slow in full screen mode. Whenever it happens I switch to windowed mode. FPS counts seem the same, but flying goes much better than. I had this problem mainly in selected systems with my old , non shader computer with 1.72. Last week I suddenly had it again with my current computer and trunk. After some flying it suddenly started. Some time later it was normal again. Here I suspect some background processes taking place. It is just strange that the FPS count is good in both cases but steering becomes bad in full screen mode and is flawless in windowed mode.

So basically the Galactic Navy slowdown comes from not pausing the AI for long enough? That sounds pretty easy to fix...

If it would be the only thing - yes. Unfortunately it's not. Using common names for nearly everything in this oxp will cause trouble too and to fix it, one will have to go through all files, check/change the references (if it's not a dependency). And then it has to be tested. The next thing would be to take a look into the models, some models have flipped faces - this can even crash Oolite. It's a lot of work and Matt is not here anymore, Nemoricus disappeared too, so if you like challenges, go for it .-)

Oh, and even 'simply' changing the AIs will be a lot of work, checking the side effects by using longer pauses (and probably changing some other things there too) will require a fair bit of work.

[Lestradae]

... some models have flipped faces - this can even crash Oolite. ...

Is that crashing a problem that can be solved Oolite-side, was this submitted as a BERLIOS bug already?

The way I see it, anything that can crash Oolite also highlights a problem with Oolite, not only the oxp ...

[Svengali]

Yupp. It's reported (not on bugtracker) and nothing new. Think about the problems with (if I remember right) the asp in aegidian-special.oxp. Kaks has solved that problem at that time by reconverting it. And it does not crash on all machines, so this is maybe related to the gfx-driver/card. And Frame also posted about flipped faces in some oxps a whole while ago (I think it was related to his nice modelviewer).

Edit: Just took a quick look and this model is used in several oxps. The asp-high.dat is (at least) in aegidian-special, x-ships, Galactic Navy5.2.2 and RandomHits1.3.6.
