#Dosbox vsync plus

Plus loads more you can see the release notes here.ĭOSBox is a truly an essential bit of free and open source software, one that keeps some truly classic games alive and so it's important that it's in good shape itself as operating systems themselves grow and evolve so DOSBox needs to keep up with it all too.It now complies with the XDG Base Directory Specification.64-bit Dynamic Recompilation - 'Support for 64-bit dynarec improves CPU emulation speed and quality across the board - this is especially visible to Linux and macOS users'.Support FLAC, Opus, and MP3 CD-DA tracks.Upgraded to use SDL 2.0 - bringing with it improved input handling, low-latency audio using OpenSL ES, more output interfaces such as Wayland and much more.Today, dosbox-staging 0.75 was officially released, here's some highlights: The point, they say, is to provide a better experience than the standard DOSBox and hopefully get their work into the upstream project to improve it for everyone. Made as an attempt to reinvigorate DOSBox development, it has a very admirable aim.

#Dosbox vsync tv

I tried running both the official dosbox 0.74 build and the dosbox libretro core on both my TV (60hz TV) and on my 144hz gaming monitor while doing my testing.DOSBox is about to get more advanced, with the community-made 'soft' fork dosbox-staging have a first proper release out. I even turned off vsync and hard sync while doing so, as neither is activated in my installed dosbox 0.74 build.

#Dosbox vsync drivers

As mentioned in my previous post, I tried to cycle through all the video drivers in the Drivers-menu (vulkan, gl, d3d, sdl2 and gdi), and I experienced no change regarding the tearing issues. It seems like that the nf file that dosbox libretro generates (by typing config -wcd in the command prompt) has no section regarding the video-output types my guess is that this task is left to RetroArch/libretro itself. If I adjusted the output-value to either opengl or openglnb however, I got the very same tearing that I'm currently experiencing under the dosbox libretro core. If the output was either surface, overlay or ddraw, I did not encounter any tearing in Jazz Jackrabbit. I also did some experimenting with the nf file in the official dosbox 0.74 build for Windows, and I made some findings regarding the output-section of the config. I even checked the config no sign of vsync activated there. It turns out that the game ran smooth as butter without any tearing, and to my surprise vsync wasn't even activated at all. I also tried loading Jazz Jackrabbit in the official dosbox 0.74 build. It had no effect in Jazz Jackrabbit on my current setup as of now. I tried your first suggestion, by changing the value of the audio maximum timing skew. Want to back this issue? Post a bounty on it! We accept bounties via Bountysource.

I even tried to alternate between all the various video drivers in the Driver menu in RetroArch. Thereby in theory most of the settings from the enhanced build of dosbox should then be read by the dosbox libretro core at least the settings that the libretro core supports as of today.Īm I doing something wrong here, or can it be that the libretro dosbox core does not properly support vsync as of today? I have tried enabling hard sync as well, and turned on and off all the various options in the Video menu in RetroArch. I have even tried to make a copy of the nf file for the ykwong Daum dosbox build, and placed it within system/dosbox in RetroArch and renaming it nf. That does not happen with the ykwong Daum build of dosbox there's even a vsync-option in the nf file itself in the main directory of that build. I have enabled vsync in RetroArch, but it doesn't eliminate the screen tearing effect completely. It is very noticeable in the game Jazz Jackrabbit the screen tears about twice as soon as you're jumping. I am experiencing some issues with the libretro core of dosbox when it comes to screen-tearing. I have been using the dosbox official and unofficial/enhanced builds for some time now, and in later years mainly ykwong Daum enhanced dosbox-builds. Unlike most of the other libretro cores, I experience various screen-tearing issues in the dosbox libretro core.
