Strange error in Dosbox

[lmerckx]

@Dragu The only difference between yours and my standard one is the
cycles=max

I 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.

[lmerckx]

@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.

@lmerckx I can help too, if there's no need to switch on a dev update branch

[lmerckx]

@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.

[Dragu]

@lmerckx
Thanks for your work. What I can still not understand, why there are different versions in Dosbox between PI2 and PI3. Just curiosity.

[lmerckx]

@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.

[lmerckx]

@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 ?

[lmerckx]

@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 !

[Dragu]

@lmerckx
I will test now. But wanted to post you picture about the last version and Jessie074. You see the hudge code.

[lmerckx]

Yes, this one is smaller in fact

[Dragu]

@lmerckx
Good news, speed is mostly back. Perhaps other compilation optimisation still possible. @voljega may also have an opinion. Thanks.

[lmerckx]

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.

[Dragu]

@lmerckx
I suppose you have a different version for PI2, I still dont understand nothing at this.

[voljega]

@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 ?

[lmerckx]

@Dragu @voljega Both problems have a solution. I will post changes for next version.
I don't really understand why there is still a performance gap. Perhaps, modifications of new version or my adaptations to maintain SDL2 patch.

I will check further.

Thanks for your help !

[lmerckx]

@voljega @Dragu It is possible to test an unstable update with this modification if you want: https://review-424-dosbox-foh6cc-archive-review-prod.recalbox.com
It's ok for me on RPI2.

[voljega]

@lmerckx sorry I don't think I will have time for it

[lmerckx]

@voljega No problem
