Retroarch 1.6.9 update slowing emulations down?

Darksavior

@andershp Speeds won't be that bad in filezilla if you use ethernet. Why not try another micro sd and update that to latest to verify a config error on your end? I can't reproduce the slowdowns you're getting in 1.6.9.

@andershp Try another microsd, maybe it has write problems. I've been updating the same retropie build for like a year, and it's fine.

SD card speed isn't going to be a factor in how fast SNES games play because those ROMs are totally loaded into RAM at once and when that happens, it never accesses the ROM on the SD card again.

@zerojay I meant possible write problems in the update he did to 1.6.9 since he said 1.6.7 works fine. I never said he needed a faster microsd to help with speeds. Rom loading is not the issue, it's the speed they're ran at. Since he's not overclocking and doesn't get any power or temp icon popups, I can just guess that it's a configuration problem of some kind since the games I tested run fullspeed on my end. A simple test of using another microsd (so he won't need to backup his current one) and updating that to latest should quickly determine that.

and a few arcade games like Armed Police Batrider (0.78) have massive slowdowns and sound stuttering...

What other Arcade games are you now having trouble with..?? i recently added support for the FixEight bootleg which did require a few
changes in the Toaplan 2 video code this might account for why Armed Police Batrider has dipped in performance as it uses said
video code as well.

i can look at fixing this but i need more people to try the game then i'll know it's not just one single user having an issue.

@gamez-fan Maybe I should have asked if he's using a mame2003 built from binary or source. I'm using binary so it probably doesn't have your fixes. I'll start building it from source now and report back.

No problem fella let me know how it goes, but im attempting a fix for this just now via some V-Blank handling that was added to the driver at the same
time as the video code was changed i think i should have backported that also it will sort any sprite lag.

@gamez-fan Ok, I tried batrider..I do notice occasional dips in fps as low as 59.7fps using stock pi3 speeds with mame2003 cf5f0b9. Solid 60fps on fba. I don't believe this relates to @AndersHP 's problem but it does verify the dips others have said.

Ok i've just committed some changes to the git for the Toaplan 2 driver which i hope will sort this.

@gamez-fan Trying 0f22fe2, I only see dips of 59.9fps now which are occasional. Fba is less common to see 59.9fps. I'm still using stock pi3 speeds. Much better performance, but I'd stick with fba for batrider.

@andershp Speeds won't be that bad in filezilla if you use ethernet. Why not try another micro sd and update that to latest to verify a config error on your end?

I only own one microSD. But maybe I could start with a clean install on this, and if it fails again, it has to be the SD? If the SD is broken, I just think it's odd that 1.6.7 works fine..?

Also see what @Slimy states here.

I will try a fresh install on my microSD, but I could also gather more data from all my installed systems if you like. A list of games that's affected, emulator versions and such. I'm no coder though, so a bit of input as to what you want to know would be appreciated.. Watch this space.

Darksavior

@andershp You can try and uninstall, then reinstall the emulators causing the problems. Not sure if that gets rid of anything that was altered. Still interesting how both of you have the same problem. You can also re-install retroarch from retropie-setup.

@darksavior
Hello from the other thread. I tried removing and re-installing retroarch as you suggested, but that did not work.

Could the slowdown have something to do with the Pegasus frontend? Both myself and AndersHP had it installed, I think. I'm not using Pegasus right now, but I did still have it installed on the Pi with slowdowns. Although the slowdown still persists after I've uninstalled it.

@darksavior
Hello from the other thread.

I must have called a thousand times :)

Joke aside, here's a list of tested games and how they perform. Note that pretty much all games I've been playing before, with no problems.

MAME2003:
1941, 1942, 1943, 1944, Alien vs Predator, Battle Chopper, Dodonpachi, The Punisher: Everything OK.
19XX, Air Gallet, In The Hunt: sound stuttering when much happens on screen. Game playable though.
64'th Street, After Burner II, Dangun Feverun: All sound stuttering, including music. Very slow video & audio. Completely unplayable.

Sega Megadrive & Sega Master System: All games tested ok!

NeoGeo (fba 0.2.97.39 romset): All games tested ok!

SNES (lr-snes9x2010):
Chuck Rock, Donkey Kong Country: All ok
Aero Fighters, Aladdin, Chrono Trigger, Choplifter III, Brawl Brothers, Donkey Kong Country 3: Sound stuttering, games playable though.
Alien 3, Clay Fighter: All sound stuttering, including music. Very slow video & audio. Completely unplayable.

This was my list. I don't know how to check emulator versions - sorry for being such a n00b! But before testing I updated everything, cores, and kernels and whatever.

Hi i only made changes to the MAME2003 codebase i never touched the code for the consoles or FBA, from the list above i made small tweak
the CPU comms to fix game speed in Avenging Spirit i suppose in doing that it might have broken the game speed for the other Mega System 1
games eg 64th street it'll be easy to revert that change if it's causing problems although it doesn't on any other platform, Sega core
has been rolled back to the previous libretro mame-2003 version so that should be good again.

You mention In The Hunt which is an IREM92 game Dangun Feveron is Cave i've touched nothing in those drivers which should affect
game speed so im at a loss here as to why this would happen in your build.

AndersHP

@gamez-fan as stated earlier, I think the Retroarch update stresses my system in a way that's giving the pi less headroom. The games struggling seems to be the ones with more advanced graphics/sound, or is it just me? I don't think this is because of tweaking in the code.

I will try a clean install tomorrow and see if that rules out my microsd.

Darksavior

@slimy I use Pegasus. My pi's performance is fine. As I already told @AndersHP, we are getting nowhere in troubleshooting this...the easiest way is to try a clean install. Also, try building the emulators from source to see if that makes a difference.

As I stated, I'm no coder. But I provided a list above, hopefully this could help? Otherwise, please tell me what to look for.

I will try rebuilding from source and then ultimately a clean install.
This is great and all, but as all my scraped art is on the SD, this process will take me many days to recover from, and will tell nothing about what happened.

@Darksavior when you say Filezilla via Ethernet, do you mean connecting my pi to my router or Ethernet between pi and computer? Have you tried writing to EXT4 with either Paragon (Windows) or Fuse (Mac)?

@andershp i suspect it's your lag reducing settings: https://retropie.org.uk/forum/topic/13263/input-lag-guide/7

retroarch updates may have changed how they affect things, who knows. if you've been changing that sort of stuff then all bets are off.

Darksavior

@andershp You can make a backup of your whole Image with win32diskimager too if you don’t want to manually backup with transferring by FileZilla.

You, sir, just saved me from a ton of work! Thank you!
@Slimy have you tried deleting your retroarch.cfg file in opt/retropie/configs/all and then reinstall Retroarch from the Retropie setup menu?

I just did this, and then transferred only my changes regarding controls, to the newly generated retroarch.cfg file, and it helped in every one of the games with issues!
