Getting up and running on 64-bit Ubuntu Jaunty

I just came across Simutrans on a link from an OpenTTD site and like the look of it!  But I'm having some troubles...

I'm running 64-bit Ubuntu Jaunty with all the non-free stuff installed.  The Debian-packaged versions didn't work well for me(v102, which is slated for the next Ubuntu release, had a fatal game save/load bug!) so I downloaded the Aug 08 2009 build.  I now have a working installation, but it, like all the others before it, is running as slow as hell!  I have a dual 2.8GHz Athlon 64, but it's acting like a 900MHz Celeron.  Even 5-10 frames per second is maxing out one of my cores, and there are occasionally seconds-long pauses where the game becomes unresponsive.  Is there anything I could try to improve performance?

I'm not a Linux dude, but I have seen mention of midi problems causing delays - that would be my first bit of advice: run with the command-line parm "-nomidi".

Other Linux folks might have better/other ideas :)

Thanks for the suggestion.  Unfortunately, I'm already trying that, to no avail.  :p  I'm running this command and each thing (that's half-resolution on my monitor) seems to make it just the tiniest bit better:
Code: [Select]
sim-linux64 -refresh 5 -nomidi -nosound -screensize 1280x800
But even with that, I've never seen it get above 13FPS... and that was with a tiny window on the menu screen.

Try using smaller maps, smaller cities - it speeds up once in game :)

I wish!  :(  Even at 256x256 it's really slow.

Do any of these threads help?

I know there have been problems in the past with linux-64 builds (I have no problems, but I'm on a low spec linux-32)
Those are informative, thanks.  It sounds like some of those folks are having a couple of the other issues I'm having, like the mouse not responding to clicks... although that was reported with v100, and I'm using a 102 nightly.  I also noticed that, strangely enough, my problems get a lot better when the simulator is in fast-forward!  Then it actually runs very smoothly and I can click things reliably without lags.

Maybe it'll be worthwhile to see if running a 32-bit version (still on my 64-bit OS) will help clear up some of these issues...  I don't know if I'm still an outlier, but I use only 64-bit OSs these days, except for VMs.  :)  Even if it's only to get a full 4GB of RAM, it's still worth it.
