Strange error in Dosbox

@Dragu Sh... Can you send me your confiuration file anyway ?
-
keeps getting stranger and stranger !

@lmerckx
Sure, but they are not all the same :# This is the configuration file for DOSBox 0.74. (Please use the latest version of DOSBox) # Lines starting with a # are comment lines and are ignored by DOSBox. # They are used to (briefly) document the effect of each option.

(Press ALT-Enter to go back) # vsync: Sync to Vblank IF supported by the output device and renderer (if relevant). # It can reduce screen flickering, but it can also result in a slow DOSBox. # fullresolution: What resolution to use for fullscreen: original, desktop or a fixed size (e.g. 1024x768). # Using your monitor's native resolution with aspect=true might give the best results. # If you end up with small window on a large screen, try an output different from surface. # windowresolution: Scale the window to this size IF the output device supports hardware scaling. # (output=surface does not!) # output: What video system to use for output. # Possible values: surface, texture, texturenb. # renderer: Choose a renderer driver if output=texture or output=texturenb. Use output=auto for an automatic choice. # Possible values: auto, opengl, software. # autolock: Mouse will automatically lock, if you click on the screen.

@Dragu The only difference between yours and my standard one is the
cycles=maxI prefer now auto for most games. But, I'm pretty sure this is not the cause of the problem.

@lmerckx
I just rolled back, as I have a few versions in usr/bin, easy with rm and cp.
But there is no effect as you expected. -
@dragu "The truth is elsewhere"
Can I use you as tester ? Because I'm blind without RPI3.I will first compile a previous version (17.12.01?) of the code in current environment to detect where the problem could be.
If it's still lagging, it could be a problem in "inherited" compilation directive.Recalbox 9.1 on RPI 4, SSD 250Gb, 2 Logitech F710, Nespi4case

@lmerckx I can help too, if there's no need to switch on a dev update branch
-
@voljega Thank you too. For a simple test, it will be preferable to simply update the dosbox executable.
Perhaps a first version available this evening. -
@lmerckx
Thanks for your work. What I can still not understand, why there are different versions in Dosbox between PI2 and PI3. Just curiosity.
-
@Dragu I don't know either: same sources, same compiler directives (in package).
It is why I want to check if it can be external to the package. -
@Dragu @voljega Here it is: https://www.proximuscloud.be/web/app/share/invite/3LrasrDfoc
It is a dosbox RPI3 (r4063), compiled in current environment. -
@lmerckx
Hi dear, I just tested but no improvements of speed. What I can still not understand is the hudge volume of this file for Recalbox PI3. Jessie version 0.74 is about 2.3MB, Windows version 0.74 about 3.7MB and this here about 5.5MB. Could it that this is a 64 bit compilation ? Perhaps a switch option ? -
@dragu Things become clearer (I hope) ...
Not a problem of 32/64 bits but I suppose a compilation directive change (unexpected).What about this one: https://www.proximuscloud.be/web/app/share/invite/r5zB6k7h7b
It is the new sources (virtual keyboard + b*mp) but the old way to compile !
-
@lmerckx
I will test now. But wanted to post you picture about the last version and Jessie074. You see the hudge code.
-
Yes, this one is smaller in fact

@lmerckx
Good news, speed is mostly back. Perhaps other compilation optimisation still possible. @voljega may also have an opinion. Thanks. -
The compilation directives are back to normal, but code has been updated (b*mp to more recent version). It can be the differences.
After testing, it is faster for me too ... but not drastically.Recalbox 9.1 on RPI 4, SSD 250Gb, 2 Logitech F710, Nespi4case

@lmerckx
I suppose you have a different version for PI2, I still dont understand nothing at this. -
@lmerckx
@dragu said in Strange error in Dosbox:@voljega may also have an opinion. Thanks.
Tested Epic Pinball, Doom, Wacky Wheels they all work fine with no lagging in image and sound
However Tyrian and Tyrian 2000 still lag a little (mostly in sound) and I'm pretty sure they were working fine before (not 100% sure, though, I may have tested them on my PC and without sound on Pi and thus not noticed sound lagging)Maybe @dragu could compare those two ones with his old version ?
