Choppy sound when in full screen mode
When running WinUAE 1.3.4 or earlier in full screen, native resolutions (such as when playing games), the sound is very choppy.
This problem disappears when switching to a windowed display. My machine is a 2GHz Pentium Centrino laptop with a high-end 3D Nvidia video card with 128MB video RAM and 2GB RAM, running WinXP Pro. Regards, Bogdan |

You have to give more details about your display page settings, mainly frequency and sync.

I'm pretty sure Toni will have a look when he's here. In the meanwhile if you could post a Winuae log file (it's on the WinUAE dir - make sure you have the option ticked on the config) that would most likely help - It's usually hard to see what specific issue it his without the log of what happened during the emulation, particularly if it's a new problem no one had before.
Run with the log turned on, during the sound getting choppy, exit, and attach the resulting WinUAE log file to one of your posts. |

Do you have exactly same windowed and fullscreen resolution? Vsync-checkbox not ticked? (vsync is usually the only reason for slowdowns in fullscreen, fullscreen is usually always slightly faster than windowed)
ADDED: You said you use laptop. Perhaps power saving settings are causing the slowdown. |

Try 16/32bit colors. 8bit may lack some hardware accelerations. Not sure though...

I was surprised to find out that this problem manifested itself when my PowerMiser settings were set for power conservation. That is the video driver underclocking to save battery power (Nvidia card options).
Normally, I underclock my video card to keep it running cooler, since it makes no difference in most 2D applications. I bring it up to normal speed for 3D CAD and other simulation programs. Well, under normal speed, all is well with the emulation sound in full screen AND in windowed mode. A big thank you to everyone! Bogdan |
