lr-duckstation - Experimental new PlayStation 1 emulator

IGA

@lostless Ok-ok. Firstly i've tested my problem games on real ps2 hardware, then on ps3 ( yeah, there are emulator too), they not showed fps too, but runs faster. Then i've run duckstation or epsxe on pc - speed of games was the same.
So after that made conclusions that those games must runs in 30 fps in any moments ( like on original hardware)
On Pi4 i could not reach this speed on pcsx-rearmed core, it runs only 25 or lower.
So, now, on the advice of @dankcushions became to use duckststion core and only believe that is it work with correct speed...

Does this also work in reverse?

I answered my own question, it does indeed work in reverse. I have a game I'm sure I've saved since I switched to duckstation. Switched Duckstation core option to use Libretro .srm as memory card type, then named the _1.mcd file back to .srm and it loaded up fine.

What about nfs games and duckstation core? - 1,2,3, high stakes are have sound issue and much slowdowns with default setting on Pi4. Only Porsche Unleashed works well.

It's duckstation problem or need special configurations??

lostless

@iga not sure if it’s changed, but the original configuration of duckstation uses hardware acceleration, which has been causing some slowdowns. Try using the software renderer and see if it fixes the problem with slowdowns.

IGA

@lostless I am always use software gpu render as default for all games - i use comopsite output...
Did you try to test some of nfs games?

maybe verbose log will be usefull?

slowdowns and sound glitches appears even at in starting menu

@iga no slowdowns here. Smooth as butter (As much as a ps1 game can be).But my pi4 is overclocked to 2ghz. That might be way. I’m also running the games off a usb 3.0 stick and uncompressed. Doubt that makes much difference
Maybe try the games in pcsxRearmed and see if they run better. It does have lower hardware requirements.

strange....
Yes, i've used chd images, but after that i've tried and uncompressed too - no effect.

On pcsxRearmed works seems to be well... ( but I already don't know this is " seems to be well" is right correct or not like in the following cases with another games on pcsxRearmed, that's why prefer duckstation)

IGA

Next question - images that .ccd + .img - no music
Or duckstation not support this format ?

you can see the supported extensions in the help of the module in retropie-setup: https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/libretrocores/lr-duckstation.sh#L14

@dankcushions Thank you!

But what about need for speed games? - is it only my personal issues and all anothers pi4 users played well on duckstation?

dankcushions

@iga i don't have these games, but your log doesn't show a slowdown:

[INFO] Threaded video stats: Frames pushed: 4915, Frames dropped: 2.

you were only playing for a minute. Are you sure you encountered a slowdown in this time?

Do other (non NFS) games work full speed? Please provide your /opt/retropie/configs/all/retroarch-core-options.cfg

IGA

@dankcushions yes, slowdowns-freezes begins after intro movie at start menu and further. I don't have enough patience to try test more than minute.....

Other games, that i've tested, work well, seems to be... Problems only with nfs 1,2,3, high stakes

There my retroarch-core-options.cfg
or file itself

dankcushions

@iga the settings seem fine. please post your /opt/retropie/configs/all/retroarch.cfg and /opt/retropie/configs/psx/retroarch.cfg

IGA

@dankcushions
/opt/retropie/configs/all/retroarch.cfg
/opt/retropie/configs/psx/retroarch.cfg

/opt/retropie/configs/psx/retroarch.cfg

bingo. both of these are non-default, which tells me you've adjusted retroarch settings in the menu, and saved, and now are running sub-optimal settings. for example

audio_driver = "alsa"

is a (much) slower audio driver than the current retroarch default, which is alsathread, which it will default to unless you override it in your config, which you have done.

i suggest you reset to defaults:

navigate to /opt/retropie/configs/all/ and check if you have an retroarch.cfg.rp-dist file. if so, delete (or rename) retroarch.cfg and rename retroarch.cfg.rp-dist to retroarch.cfg
repeat in /opt/retropie/configs/psx/

IGA

@dankcushions said in lr-duckstation - Experimental new PlayStation 1 emulator:

audio_driver = "alsa"

-I've already tested with alsathread too - same effect!

And i am sure - i don't changed audio driver by myself - alsa was default after retropie installing...

Ok, i will try to rename current configurations cfg.rp-dist and try again

correct, i didn’t say you did, and you’re right it was defaulting to alsa in earlier versions of retroarch, and then changed to alsathread in later ones.

the point is, by going into the RGUI and adjusting any settings, and then saving that config, you make ALL the current retroarch settings permanent, so any changes to the defaults by retropie or retroarch would have no affect. you’re now the owner of the retroarch settings and are basically running your own retropie spin-off.

for this reason i would not recommend changing retroarch settings via the RGUI and instead use https://retropie.org.uk/docs/Configuration-Editor/ - this only inserts the single setting you change to the config rather than setting EVERYTHING.

@dankcushions good to know, i never used the Configuration-Editor and made all changes via RGUI over the years :/
So i am running also my own retropie spin-off, i guess i will start to create a new setup in the future (Pi5) .

Good luck: i never had problems.
I also had to change to ALSATHREAD by myself (did that in RGUI as well), but everything works great.
I also tested "NFS IV: High Stakes" yesterday evening and played a couple of rounds on "Landstrasse". No problems at all.

well... i firstly download retropie in January-February of this year - it was 4.7.1, and then immediately did update - so, i ve supposed that use latest current version...

And i don't changed in retropie-setup gui anything else by my own, I've make changes in game process in retroarch -> quick menu->options or controls. In first "settings" retroarch menu i am only make visible fps in left corner and applied it to all cores. That's all....
