I use the atari800 emulator v. 4.2.0 on windows 10 and linux in latest version. (https://atari800.github.io)
I notice an annoying keyboard latency of up to 100-200ms (keypress-to-click and appearance of the letter, rough estimation), which is not present on real hardware. How can I get rid of the latency and make the emulator behave like a real Atari 800XL machine?
Additional Info / Update:
I testet it with the build-in roms, also with real atari 800 XL OS and atari basic rom both on windows 10 on a pretty powerful machine (Surface Book 2) and also on Linux Mint deb-package (older version - three.something. I uninstalled it and don't remember the exact version number)
I also compiled a version myself as a pure fb-console programm (emulator v.4,2,0) against SDL 1.2 (2.x does not support fbdev anymore, sooo sad...).
Same issue on all OSses and machines.
Games, demos run fine, it is just the annoying delay between each keypress and the click sound/character appearance. It is not much but noticeable, especially when I type faster.
There is no keyboard delay in the Altirra Emulator. (http://www.virtualdub.org/altirra.html) but this is only available on windows.
Do I need some special settings on atari800 to remove latency or is it just an issue with the emulator?
