FS-UAE runs reeeally slow...

Hi there,


I'm totally new to this. Please bear with me if I've asked something trivial.

I run FS-UAE on Ubuntu Lucid (64bit) and tried it with Lemmings and Silkworm and the games are practically unplayable as the mouse takes ages to respond. The same goes for the keyboard when I enter the menu. I've tried it with the standard config and this one:

amiga_model = A500
floppy_drive_0 = Oh No! More Lemmings.adf
chip_memory = 10240
slow_memory = 1536
input_grab = 0
floppy_drive_speed = 800

Any help would be much appreciated.

"Ages to respond" is quite slow ;-) -So the first idea that comes to mind is that you do not have hardware-accelerated graphics. Please attach Documents/FS-UAE/Logs/FS-UAE.log (you may need to zip it down before you can attach it to a post).

EDIT: unrelated, but you probably meant to have chip_memory = 1024.

Try Set accuracy=0 to reduce cpu usage by 50%

This beauty runs absolutly fluenty on mac mini , which is the desktop entry level computer from apple. (is built up from notebook components only)
How old is your computer?

Many thanks for your support.

I've attached it as .txt.

No, that's correct. 1024kb sounded a tad tiny to me.

Done. No changes.

A couple years. I have an Amd Athlon
dual core with 2Ghz and 4Gb Ram.

/addendum: input_grab = 0 doesn't seem to work either.

Sounds like the issue, I originally had.
It turned out to be a messed up config file.

Try with a new config file with only the basics in to test.

Same hardware as me.

I used the example config to test and confirm it was a config issue.

[config]
amiga_model = A500
kickstart_file = kick location
floppy_drive_0 = adf location

Well, it looks like you have hardware-accelerated driver. But I have performance problems too when using FS-UAE and other OpenGL apps in window mode with Ubuntu/Unity - composited desktop (but more like half frame rate, not "slideshow"...)

- Does it work better with the option video_sync=off ?
- Does it work better when running in fullscreen ?
- Does it work better with Unity2D desktop ?

Well, 10 MB is more than the max allowed anyway (8MB I think). -And the default values should be fine for most games. It is possible that you create more problems than you solve by altering the memory settings

try grab_input=0, I have renamed it to input_grab in later versions ("--input-grab" and "--no-input-grab" made more sense), both are working in recent versions (I noted this in the documentation now).

[FrodeSolheim]

Another observation, regarding game compatibility: An original kickstart is not loaded, which can at least cause compatbility problems with games. If you want to emulate an Amiga 500, you should load a v1.3 A500 kickstart version for best compatibility.

I think this is the problem:

remove these values from configuration and let default values, as in sample config.

I have similar hardware configuration, Ubuntu 12.04, and had similar problems when I experimented with memory values.

Also I had slowing down issue, when I had two instances of FS-UAE running at the same time.

Thank you for your suggestions!

As I said in the OP, I have the same difficulties with the standard config, too (I gave it a try with a fresh config file anyway, without success).

No changes.

No, it's worse.

Do I have to try that? Unity2D is not supported under Lucid and I don't want to mess something up.

No, the point was to try it without having a compositing manager running (...without fancy effects such as window shadows). In earlier Ubuntu versions, "desktop effects" or something can be disabled in preferences (and compiz will be replaced with metacity).

I don't really think this is your problem, though as I said, Compiz can (and does on my system) create problems with OpenGL applications syncing to vblank, but using video_sync=off should have alleviated this problem but disabling sync to vblank.

The option

grab_input=0

should work. It has been supported since one of the first versions. If it does not work, it raises the question whether the options are written properly in the config file.

Please check for this line in the FS-UAE.log:

grab_input = 0

You should also re-run the test with video_sync=off, and check that the following lines are present in FS-UAE.log afterwards:

checking video sync mode
no video sync

Regarding the input grab: could also be a misunderstanding regarding the function. It only prevents FS-UAE fram initially grabbing input focus. When clicking with the mouse etc, it will still grab focus...

[FrodeSolheim]

Pressing Ctrl+F10 while running FS-UAE will display a performance graph in the FS-UAE window. Could you enable this function while running a game, and posting the resulting screenshot? Just let the graph run for a couple of minutes, and make sure the screenshot shows a representative snapshot of the running graph. Thanks!

Sorry for not getting back, I totally forgot this...

Indeed.

I used your instructions above and I also quit most other running applications and It seems to work now. I'll test some more to see wether I can determine the cause more precisely.

Many thanks for your support, Frode. It is very much appreciated! Also many thanks for creating this piece of software (for the few enthusiasts out there).

Hello, this thread is old but I hope help is still around. I have similar issues. The emulation is significantly slower than E-UAE and CPU-Usage is at 80% or so. I have looked for a config and log file but did not find any. Where are they (ubuntu linux 12.10 64bit, 2x 2,7 ghz)? greetz, ags

ps: another issue is, that the cursor keys are not recognized. This is the same for E-UAE on two different PCs.

[FrodeSolheim]

Log file is in $XDG_DOCUMENTS_DIR/FS-UAE/Cache/Logs (recent betas) or $XDG_DOCUMENTS_DIR/FS-UAE/Logs (2.2.x). Please post the log file here, and also try the steps in this post: http://eab.abime.net/showpost.php?p=818693&postcount=7.

Regarding cursor keys, see http://fs-uae.net/faq.

[AGS]

What is an '$XDG_DOCUMENTS_DIR? Is the config file also there?

[FrodeSolheim]

It's ~/Documents on most distros (sometimes just ~). So look in ~/Documents/FS-UAE. If you have created configs with the launcher, they'll be in ~/Documents/FS-UAE/Configurations.

[AGS]

And there is another thing: FS-UAE permanently produces files '<filename>.uaem' to every file accesses in write mode. Can this be turned off?
