  $VER: Amiberry 5.6.1 (2023-06-13)
  Usage:

  -f <file>                  Load a configuration file.
  --config <file>            
  --model <Amiga Model>      Amiga model to emulate, from the QuickStart options.
                          Available options are: A500, A500P, A1200, A4000, CD32 and CDTV.
  
  --autoload <file>          Load a WHDLoad game or .CUE CD32 image using the WHDBooter.
  --cdimage <file>           Load the CD image provided when starting emulation (for CD32).
  --statefile <file>         Load a save state file.
  -s <option>=<value>        Set one or more configuration options directly, without loading a file.
                          Edit a configuration file in order to know valid parameters and settings.

Additional options: -0 Insert specified ADF image into emulated floppy drive 0-3. -1
-2
-3

-diskswapper=d1.adf,d2.adf Comma-separated list of disk images to pre-load to the Disk Swapper. -r Load main ROM from the specified path. -K Load extended ROM from the specified path. -m VOLNAME:mount_point Attach a volume directly to the specified mount point. -W DEVNAME:hardfile Attach a hardfile with the specified device name. -S Sound parameter specification. -R Output framerate in frames per second. -i Enable illegal memory. -J Specify joystick 0 (x) and 1 (y). Possible values: 0/1 for joystick, M for mouse, and a/b/c. -w CPU emulation speed. Possible values: 0 (Cycle Exact), -1 (Max). -G Don't show the GUI, start emulation directly. -n Enable Immediate Blits. Only available when illegal memory is not enabled. -v Set Chipset. Possible values: 0 (OCS), 1 (ECS Agnus), 2 (ECS Denise), 3 (Full ECS), 4 (AGA). -C Set CPU specs. -Z Z3 FastRAM size, value in 1MB blocks, i.e. 2=2MB. -U RTG Memory size, value in 1MB blocks, i.e. 2=2MB. -F Fastmem size, value in 1MB blocks, i.e. 2=2MB. -b Bogomem size, value in 256KB blocks, i.e. 2=512KB. -c Size of chip memory (in number of 512 KBytes chunks). -I Set keyboard layout language. Possible values: de, dk, us, se, fr, it, es. -O Set graphics specs. -H Color mode. -o = Set Amiberry configuration parameter with value. See: https://github.com/midwan/amiberry/wiki/Amiberry.conf-options

Example 1: amiberry --model A1200 -G This will use the A1200 default settings as found in the QuickStart panel. Additionally, it will override 'use_gui' to 'no', so that it enters emulation directly.

Example 2: amiberry --config conf/A500.uae --statefile savestates/game.uss -s use_gui=no This will load the conf/A500.uae configuration file, with the save state named game. It will override 'use_gui' to 'no', so that it enters emulation directly.

**Additional context**
I have used some old releases and I have not noticed any performance drop, but now I am...

When do you notice this?

[Chandler-Kluser]

when I switched my operating system from EndeavourOS to Arch Linux, it is important to notice that the old release was kept during the system transition so I did build it from source again to test if it was something like shared object issue or something like that.

[Chandler-Kluser]

in a clean build using Amiga1200 core with workbench I noticed this issue by opening AmigaAMP:

I don't know if it is something related to the performance...

I have also tested different sound/video configuration specs, but the problem persists (I have never noticed any performance issues in older times, by the way)

[solskogen]

What do you means by performance, then? It might look like you have a problem with the sound. Make sure that works.

[Chandler-Kluser]

it is not only the sound, the video is laggy and the emulation itself too

[solskogen]

You have to provide more and better information. It seems to be a problem with your system and not amiberry itself (amiberry is just the symptom) - moving over to discussions.
