hello. my game run slow...

Hello !

I'm happy to see such a big transport tycoon community

Recently i've installed my transport tycoon (open ttd) and I am playing a very large map (bigest, i think it's 2000 X 2000) and after 7-8 years (in game), my transport tycoon runs slow. Mouse cursor moves in frames and game runs slowly. I have a P4 3000 Mhz (hyper thearding) and a Geforce Fx 5200. My computer is guilty because of that ?

And how can i fix this problem. I've changed the graphic pack to the oldest one (like tycoon classic) and i have same problem. How can i make my tycoon running normally ?

Thank you in advance!

Big maps can eat a lot of CPU power. And the more vehicles then are added (and houses and industries added to the map), the more of it is needed. On a P4 I easily imagine that you hit the limit of your CPU with that setup.

Play smaller maps. Changing the base graphics type will not have an effect. Using less NewGRFs might have a small effect, but by far not as much as reducing the map size (2048x2048 is 4x larger than 1024x1024 and thus map-specific stuff takes 4x as long and also things like path finding is considerably more cpu intensive for vehicles.

What version of OTTD are you playing? Are you using any GRFs?
Either way, the likely answer is that your processor does not have a fast enough clock speed to handle such a large map. Try a smaller one

Thank you for reply's!

I think I will by a new computer to play tycoon haha (I never though i will ever say this).

I love big maps because you can play them a lot of time...

Anyway, one more question and I'l leave... Can I setup to start with all 12 opponents in the same time ? Where ? Because after every 12 month when they arriving, I'm getting stronger and the game has no charm...

In the AI config (accessible from the main screen) you have the option to set the delay for each of the AI in their configuration settings.

i had CPU load issue and partially solved it by limiting max vehicles to 500 instead of 1000 (i prefer trains and ships, can't imagine running even 500 trucks). It have great impact once AIs will spam up to max limit of vehicles, trains, ships, and all of it moving and loading CPU. Planes also have great impact, as they move very fast, so you can try to disable it for AI's (some of the AIs will be disappointed). Currently i play 1024x256 map with max 1000 trains and 500 vehicles, on 512Mb of memory ) works ok. also pay attention to background processes, unload everything like antivirus, daemons, IMs, update apps. i use this PC for coding purposes and installed openttd just to try it out, never tought it will run on such low resouces, but it does ) so you have good chance to tune your setup.

Ships are the worst in terms of cpu usage. Aircraft are probably the least cpu consuming. If you want to use ships, use lots of buoys.

Actually (some) AIs are the worst for CPU usage. you can test this by going to the ingame console and type "stop_ai <number>" (this will delete the entire company). if that gives a significant speedup, then tis was the problem. if not, then go back to your savegame before you ran these commands.

Check that you are using the recomended pathfinder on Advanced Settings->Vehicles->Routing. Original pathfinder for ships slows down games a lot.

If you go for a quad-processor, get a fast one, as most of the processing in OpenTTD run in a single thread. Some blitting and compressing of savegames happen in a second thread. Thus for OpenTTD a fast dual-core is usually better than a slow quad-core. (given everything else equal) The graphics card is not important, so don't waste your money here if you want to get a fast computer for playing OpenTTD.

As far as I know it's just the opposite...

I think that's an old wiki page that hasn't been updated in a while. In my (recent nightly) version of OTTD it says that YAPF is recommended, even for ships :!:

Despite YAPF being recommended, the original pathfinder is still faster to my knowledge. It seems to be some sort of local greedy search.

the original pathfinder is "faster", because it pretty much doesn't work at all... ships regularly fail to find a path even if the target is straight ahead (most obvious on diagonals), then make a random turn in the general direction, and hope they actually end up where they should...

i can confirm. i just switched to yapf and ships started to follow their routes better. at the other hand i've experienced a lag. looks like default pathfinder fast and dull, when yapf works better and increase CPU usage.
