severe performance problem

[mausie]

i am having severe performance issues when i play the game with my

Pentium 4 @ 3.4 GHz
3 GB ram
HD 3850
Windows 7

when i play with my laptop celeron 1.4 the game is smooth, the laptop uses windows xp

I installed openttd 1.3.0 + nightly and the game is lagging.
It makes me want to stop the game.
I copied my save game from my laptop to my desktop, I don't know if this matters

When a train is moving u actually see that it is lagging like the system does not have enough power
please help me

[mausie]

i have no idea why i have this problem, i hope someone can help me

Can you upload your savegame? I can't reproduce this with r24917.

What is your CPU usage according to the Task Manager?

[mausie]

where can i send the screenshot + save game to?

[mausie]

r24917 is the beta 1.3.0?
maybe it is verion related?

try to increase the sprite cache size in your openttd.cfg

try to increase the sprite cache size in your openttd.cfg

can you tell me how please?
and how much should increase it?

i am trying to look for it but i cant seem to find it

You can just attach it to your post, below the reply field there is a form to add attachments (don't forget to press Add file).

r24917 is a newer version than the beta.

See the wiki. I don't know what value it should have (or what value is preferred).

[mausie]

even 24922 does not work

sprite size changed from 128 --> 256 --> no change.
the game like it is running on a 120 mhz pentium 1 and becomes a slide show

screenshot added

[ChillCore]

Sprite cache size 64 will do.

Thank you for the screenshot but there is little we can do with that ...
Please upload your savegame too so people can have a look at number of active AIs and other system slowing factors.


ps:
There is an edit button under your previous posts when you are logged in ...
It would be nice if you could use it if you have something to add in a timespan of minutes; it will remain active for seven days (just in case you would ever want to correct info, or whatever, later on)

[mausie]

there is no AI, it's just me..
Uploading my savegame doesnt work, for the last 20 minutes it is uploading, sth is wrong.
is there another way to send it

sprite size set to 64 seems to make it worse.

my poor celeron 1.4 out performs my 3.4 ghz p4

The forum allows files up to 6MB; if your file is bigger you will have to upload it somewhere else and post the link to it.

If you really have no clue where to put it ... maybe create a windows live account (just for the purpose of sharing files) and put it in a public skydrive folder.

i hope i did it good

Well, you're playing with a very large map, with loads of towns and industries. This is simply a very resource-demanding thing to do. A performance problem on non-high-end machines under such circumstances is to be expected.

In the future, I suggest playing with a smaller map, that will help the most.

[PikkaBird]

Your game runs fine here, but I've got a considerably better processor than a P4. I'm wondering if the issue is with autosaving, since you only have a single threaded processor.

I agree with Supercheese, perhaps you should consider playing on smaller maps. Your savegame contains a thousand towns and over three thousand industries, 95% of which you have never interacted with in 240 years of gameplay. Why waste processor time on such vast expanses of untouched scenery?

Edit: Late ... as usual ... /me hits submit anyways.

Yep, that went fine.

Your game seems to run fine, compared to other games and considering the circomstances.

I think your biggest problem is with the mapsize and the number of towns and industries present.
If you do not want to start a new game on a smaller map (almost no-one fills a 1024 *1024 map alone) which will give the biggest boost, I would start by decimating at least half of the cities and industries in the scenario-editor (you can always re-add some if you run out of things to transport).

That does not explain why on each of your computers it runs at different speeds ofcourse.
Difference in hardware (memory, graphics card), configuration, OS?
Does it happen with other games too? Ifso give your old p4 some room to breathe and install XP or a flavour of Linux.
Maybe a silly question but you do test with the same revision and same config file on both machines?
Did you start this game with an older version and are doing something you did not do before ... zooming in a lot or using ZBase?

[mausie]

i dont agree..


like i said my mobile celeron 1400 mhz is playing the game fine...
my 3400 mhz p4 is struggling. i can play crysis and far cry 2 but not openttd while my very old laptop can run it smooth??

there must be another cause..

[Supercheese]

You could try disabling autosave, if you have autosave enabled. Maybe that will help.

Could be that those 3D shooters run better as they do not hanled the entire map (and everything in it) at once at any single point in time, which OpenTTD does ... from beginning to end.
Does your celeron handle Crisis well?


Anyway, no-one is saying that there can not be something else at hand ...
Can you post your config file too please (remove the passwords if there are any)?
