@thestarglider :P

I'm a bit curious, does it improve things for cps3 emulation on pi3 ? Having slower paced emulation might help with the slowdowns ?

I wouldn't know. I don't really play any CPS games!

This wont make any difference retroarch is running anything 57 - below 60 at 60fps. The only people it will make a difference too is someone on a machine that supports freesync or gsync or if they know how to change the audio skew. It certainly will make a difference on the otehr fbneo ports though.

@grant2258 afaik, it's not exactly how it works, someone tried to explain it to me in https://github.com/libretro/FBNeo/issues/201#issuecomment-558593311 :

if you have freesync/gsync (and a compatible gpu ?), your monitor is able to use any refresh rate, so the game will render perfectly at the proper framerate
if you don't have freesync/gsync, there is no way your monitor can adapt to the game's refresh rate in the first place (that's simply impossible from a hardware's POV, whatever the frontend), so retroarch will use frame duping mecanisms to fake it.

Also, it seems 2 settings are required : vsync & adaptive sync. I can't find the second one in RA's setting menu, but it seems it can be enabled in configuration file through video_adaptive_vsync = "true"

As a matter of fact, even if the fps counter is really jumpy on retropie's bundled RA, i can confirm this change from 60 to 59.59 affects framerate in sfiii2 on my pi3b+.

its easier to just adjust the audio skew in all honesty should work or you could set it up through. Both ways will work but needs user input either way. By default RA is speeding the games up to 60fps see robocop for example you can notice the sound pitch rising and how fast the character moves. It not duping by default it running 60 fps

Darksavior

@grant2258 I knew there was something off with robocop..

grant2258

it can be fixed by setting the audio scew or through gsync/freesync method I always found the audio scew adjustment better. Mame 2003-plus will bypass this automatically so no need to set anything.

@Darksavior do you have the sonic3 rom for the megadrive thats pal games not sure how they are running havent checked that out on the libretro core to be honest ill need to check how this sub system works to load it. Is a bit of pain to do on the pi though need to check it out though at some point

Darksavior

@grant2258 I can get the console set but there's too many sonic3's. Happen to know the name?

grant2258

sonic3.zip is the name pal games should be ok to be honest someone would have picked it up by now if it wasnt is worth checking though

Darksavior

@grant2258 Won't load. I'm probably doing something wrong. I had to make a whole new section for it in emulators.cfg to load the proper subsystem. A guide post at the libretro forum doesn't say it needs a bios and log says nothing.

Good news : this week i did some improvements to cps3 emulation (list available at https://neo-source.com/index.php?topic=2487.msg28612#msg28612), i did some quick performance test on my rpi, and it appears those fixes improved speed for me.

WeirdH

@barbudreadmon Awesome work! Is the update already there if we update from source now?

barbudreadmon

@WeirdH yes

WeirdH

And now I've messed stuff up, of course. Some games glitch out or don't start anymore after updating. Do I need updated roms too?

Rebuilding with clrmamepro and the dat-file from here didn't work. (Granted, I am still a bumbling fool with clrmamepro...)

grant2258

best thing to do would be check your logs it should tell you about missing roms

WeirdH

@grant2258 Hm, my runcommand.log only says this:

Parameters:

[CDROM] No sg devices found and sg kernel module is not loaded.

and my es_log.txt ends with

Are those CDROM and ARB_texture things my problem?

Clyde

@WeirdH Did you enable verbose logging in the Runcommand menu?

That's the ES log, doesn't log anything emulator related. As @Clyde said, enable verbose logging in the Runcommand launch menu and then post the /dev/shm/runcommand.log file on pastebin.com.

I'd also ask to create a new topic with this, since it's not related to the topic starter.

Will do, thanks to you both for replying. New topic created in 'Help & Support', apologies for the thread pollution here.

You can't start a game with unmatching crcs in fbneo, i disallowed it last year (too many abuse), so yeah the romsets that won't start probably need to be updated.
Give more details on the games glitching out please (might be related to https://github.com/finalburnneo/FBNeo/issues/278 ? if so, it got fixed already).

WeirdH

@barbudreadmon Thanks for replying. The problem has just been resolved, when I tried this suggestion by @grant2258. Everything is working fine again.
