What the fastest possible x64 emulation way of OS4 today ?

@balaton
No doesn't work either unfortunately. Font is getting scrambled again when going into windowed mode and switching to windows and back to AOS4.

And as mentioned earler: When staying in SDL fullscreen (without gl=on) as well when using GTK everything also looks fine.

If it works with gtk why don't you use that? Does it unscramble when switching back to full-screen? So only shows problem in window or stays like that even after going back to full screen? What if you resize the window? The problem is probably that SDL does not handle scaling to 0.99% or just a few pixels less too well. I don't know SDL, maybe there are people here who know it and know about something that can be set for it to use better scaling algorithm.

Unfortunately it does not descramble when switching back to fullscreen. Resizing I need to check still. But with GL=on it seems sometimes it does.
But with GL=on I got freezes for some seconds every ~30s, so I removed it.

GTK I did not yet use since I read somewhere it would be less performant. And I struggled with mouse pointer handling there. But will switch to it.


Update: Seems GTK has issues when using different screen resolutions while in full screen. E.g. running WB in 1920x1080 and opening an 1024x768 screen => after closing that screen WB stays in the lower resolution until switching to Window mode.

Does the zoom-to-fit option has an effect on that? You probably won't notice a performance difference with gtk. SDL is nice but if it does not work then not many other options left. I've heard some people had problem with mouse on Windows with gtk. Adding -device usb-mouse may fix that, if not a better option is -device usb-tablet but that needs a driver in AmigaOS which I think was posted somewhere here a while back but I don't remember when and where.

If all else fails QEMU also has a built in VNC server so you can view it with a VNC client. No need to run VNC server in the guest but that may not be very convenient so try when exhausted all other options. You can check with -display help which display backends are available in your build.

You could also try setting lower resolution in guest and use it in a window to avoid scaling.
