lr-duckstation - Experimental new PlayStation 1 emulator

@dankcushions As i've said in slowdowns in psx games thread - i had always 60 RA's and 25 internal.... so it NOT means the emulator is running at full speed, in my case at least)
-
@iga you're confusing terminology. if the FPS via RA is 60fps, then as far as the emulator (in your case pcsx_rearmed) is concerned, it IS running full speed. the issue is that it's inaccurately emulating the cpu (or something along those lines) so the game is slowing down more than it would on real hardware.
ie, 25 fps internal and 60 fps internal means that the emulator is saying i am full speed, which in this case means running a game at 25fps.
-
@dankcushions Ok, i just wanted to get is this problem of raspberry or pcsx-rearmed
-
@iga basically what @dankcushions is saying is that if retroarch is reporting 60 FPS, the emulator is running full speed and not lagging. Now most games on psx ran at a lower FPS on original hardware, and also some lagged on real hardware and that is also being emulated. Also emulators may have bugs that add additional lag where there wasn’t before. But Think of it like the psx has to send a 60hz signal to a tv, but internally runs lower. But it’s not an issue with the pi unless retroarchs fps dips below 59-60
-
@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.mcdfile back to.srmand 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??
-
@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.
-
@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)
- strange....

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

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

@dankcushions
/opt/retropie/configs/all/retroarch.cfg
/opt/retropie/configs/psx/retroarch.cfgbingo. 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 anretroarch.cfg.rp-distfile. if so, delete (or rename)retroarch.cfgand renameretroarch.cfg.rp-disttoretroarch.cfg - repeat in
/opt/retropie/configs/psx/
- navigate to
