This can be toggled in the menu once hataris loaded, but maybe a good performance option to set as default (esp for RPI1 users)\r\n\r\nIm using both  with  \"hatari --timer-d 1 --zoom 1\"\r\n\r\non a further note its worth looking at the mercurial repo.  the latest dev builds support SDL2 scaling and vsync.  http://hg.tuxfamily.org/mercurialroot/hatari/hatari  \r\nit also seems to have resolved the annoying bug with menu buttons \"sticking\" on the file browser\r\nneeds configuring with ./configure --enable-sdl2\r\n\r\nAll tested on Raspberry pi 2\r\nperformance references http://hg.tuxfamily.org/mercurialroot/hatari/hatari/raw-file/tip/doc/manual.html#Performance\r\n\r\n\r\n\r\n"}}
