Re: DosBox-0.74-ES (SDL2)

Posted on 2018-01-08, 22:01

New build posted (https://github.com/aqualung99/dosbox-0.74-ES/ … dows_010818.zip) with fullscreen aspect ratio correction. That scaling code all needs some work. I think the next immediate concern is to expose vsync on/off as a property in the .conf file.

@Diduz that was an accidental oversight. I am flying blind with this problem somewhat; the build was working quite well yesterday (so I quickly posted it!) but today after messing about with some settings and some code, I am back to the same old problematic behavior. Even more bizarrely, the same …

Been gone for a while -- just wanted to post an update about the performance problem with frameskip=0 in my build. I've posted a new build (https://github.com/aqualung99/dosbox-0.74-ES/blob/master/dosbox-0.74-ES_Windows_010718.zip) that, when combined with the latest nVidia drivers, appears to clear …

Bummer. Are you willing to help try to narrow down what might be going wrong? The next thing I would want you to do would be to do a sanity test against the old DosBox official 0.74 release. Do you happen to have that old version around? If not, I can make you one. If that version works perfectly …

This is with the old 0.74 code. I always had trouble with "auto" in that version; and in fact if that code is using any kind of per-frame rendering times to help it figure out how fast to go, then my changes might have made the behavior it even worse. It didn't really cause a reboot though -- it …

I think it's related to the code in DosBox that attempts to automatically adjust CPU cycles. It no longer functions correctly. When I use your .conf file, all sorts of bad things happen to my computer and I have to reboot! :) Please find the line in your .conf that reads: "cycles=auto" and change it …

That doesn't sound so good. The Lottes2 shader is *very* demanding -- with branches, etc. It could be that your video card is having difficulty keeping pace. You can test that theory by using a smaller window: if fewer pixels has a dramatic impact on performance, then the video card is likely your …

Thank you for the kind words. I appreciate the support! Perhaps I should take a look at the extent of the differences between my branch and the current SVN as a next task. Because I don't really know how large or small a job that may be. Although if the current SVN is still linking to SDL 1.0 it's …

Also, you are getting some precision errors in your output. That's the cause of the occasional missing/extra vertical row of pixels. I see this on the ARM GPUs all the time because they use very low-precision floats (8-bit I believe.) You can very likely correct this problem (depending on your video …

Thank you! Yes, I still have a lot of passion for this project. Unfortunately work gets busy sometimes and I don't have as much time to spend on it. Once I have the time though, the improved OPL3 is high on my list. Probably 2nd is porting over the 3Dfx/Glide work that has been done in the community …

And for the sake of completeness, if you didn't like the Lottes2 but just wanted regular bicubic filtering, you would make sure these lines were set like so: pixel_shader=.\Shaders\DosBoxMain.ps vertex_shader_pass2=.\Shaders\fb_bicubic.vs pixel_shader_pass2=.\Shaders\fb_bicubic.ps perform_2pass= …

Might you possibly have 2-pass enabled? You normally don't want to mix the two. If not, it might be a bug...what kind of video card do you have? I usually run with the Lottes2 and here is what my [sdl] section looks like: fullscreen=false fullresolution=1920x1080 windowresolution=1333x1000 output= …

Does this branch accept new shaders as plugins, and if so, is there an instruction on how to add a custom shader? EDIT: I should like to implement my pixel-perfect patch as a shader for your branch of DOXBox, but I shall need such variables as the output resolution and the aspect ratio as …

Any chance to see a compilation build of this fork? I don't know what a compilation build is, but I've posted a Windows binary for Windows folks who may not be able to build this themselves. I don't have a real hosting site, so I had to keep the file size small. That means, I had to skip the …
