Problems with UAE under Linux...

[Lettmennli]

lo,
i've downloaded and compiled several versions of UAE and i've got at all the the same problem...
The Emulator is slow as hell...
normally, when Kickstart loads, it loads fast but smooth..
But at me it loads.. like u play q3 on 10 FPS...
It stocks all the time...
Do u have any idea what to do ?
Here is some information out of the shell:



lett@linux:~ > uae
Testing the RDTSC instruction ... done.
Calibrating delay loop.. ok - 834.25 BogoMIPS
No joysticks found
Sound driver found and configured for 16 bits at 44100 Hz, buffer is 8192 bytes

I hope u can help... cause like this it is unplayable...
The Emulator runs very slow... i must have done something wrong...
Btw. I use SuSE Linux 7.2

It *might* be useful to tell us your CPU type and frequency. :rolleyes

[Lettmennli]

I've got a Intel P III 833....
396Mb ram...
:)
Hope u can help...

OK, so it's NOT a CPU problem.
With a P166 or similar you couldn't have expected good performance with UAE, even though you are under Linux...

[Chuckles]

I didn't pick up from the original post in this thread whether the poor performance is seen only when trying to run a particular game, or if it is seen with all games. Also, I'm running WinUAE instead of the Linux version, but just in case this problem is only occuring with certain titles, I thought I'd pass this along. I do know that when running certain titles, I've seen my frame rates drop from the usual 58 fps or so to around 15 - 17 fps. Usually though, I've found that using a different Kickstart version with that title has made a difference. I had that problem just last night, as a matter of fact, and after switching from Kickstart 1.3 to 3.1, everything ran great. Hope this helps.

Can you also port your UAE config/the parameters you are using to call it please?

[Lettmennli]

K..
I cant even get into a prog. or a game... even the kickstart screen is slow as hell...
here's my config:

kickstart_rom_file=/home/lett/Kick13.rom
gfx_width=800
gfx_height=600
gfx_linemode=double
use_gui=yes

and the second problem is, I cant see the config. window with CPU-settings etc. do u know, how I can call it ?
I call UAE with uae.. for example:

user@home> uae

And what could be the performance problem ?

Hope u can help...

You might have compiled the UAE from source without the GTK toolkit which is for displaying the GUI in uae (X11 version).
Without the GUI, it is utterly a pain in the ass of course... if you're forced to hack in every bloody parameter at the command line. :scream
If you don't know where to get GTK, I can point you to the appropriate direction(s).

[Lettmennli]

ok.. would be cool, if u could give me the link, but I think I got GTK(+) installed, cause I've got SuSE7.2 maybe the wrong version....

[Lettmennli]

He say's, that I havent got GTK+ 1.2.9 but I have got the newest version... I compiled it 5 mins. before.. how can I say to UAE that I have the newest one ? Must I deinstall the old first and install then the new one ?
Or how can I make this ?

Greets Lett :D

[Lettmennli]

Ok, i deinstalled GTK+ and recompiled it and now it works...
I found out what my Prob. is:
If I activate the sound, UAE is veeeery slow.. but if I turn it off, its speed is normal...
Do u know what to do ?

[andreas]

Whoops...;)
Well, deinstalling wasn't necessary at all. The crucial thing was that SuSE only installs the GTK+ runtime, what you need is the source tree for developers.
Nevertheless, it works, that's good :)

Could you try the sound drivers from ALSA?
http://www.alsa-project.org

I don't know which sound card you're using, but it fixed a lot of speed issues back in the beginning of '99 when I had just bought my Soundblaster Live! Value (I still have it) and there were no drivers available that worked satisfyingly enough!

[Lettmennli]

Um... I've got alsa installed allready with SuSE 7.2...
I use a SB Live! 5.1....
Do u think, i should install new drivers ?
If yes, what must i add in etc/modules.conf ?

Greets Lett :D

[Lettmennli]

Please help me...
I think, its the sound, cause its really ugly sometimes.. and slows down all the things..
I dont know what to do :(

I find the same thing with sound under uae in linux.. its pretty lame .. that is why I stick to the real thing ;)

anyhow looking thru the configure file under uae8.20 I find:

--with-sdl Use SDL library for low-level functions"
--with-sdl-sound Use SDL library for sound"
--with-sdl-gfx Use SDL library for graphics"

have you tried compiling it with SDL libraries, you might find that it runs better under that. Tell me how that goes.. I haven't really tried using those libraries, so I'll be intrested on your findings.

hope that helps.

[andreas]

5.1? Ah, that's either a Live! Player or Live! Platinum card.
I just think that the drivers aren't advanced enough yet...updating the ALSA drivers to some betas from the ALSA page might solve the problem...

Did you try to compile an old WinUAE, for example 0.8.6? It might be that the change in the sound code slows down your system.
Here you can find some old UAE source trees (ftp://ftp.freiburg.linux.de/pub/uae/sources/develop/).
