Slowdown after update to 4.2

[obsidianspider]

@IronAvocado No worries there. On my x86 instance everything has to install from source and it takes around two hours to update everything. On my Pi 3 it only takes a few minutes.

[Dochartaigh]

To be blatant, everything after 4.1.5 (or there about) has been much slower. I notice this the most because I'm mainly messing around with Pi Zero's where every little change in the programming is noticed 4 times as much (since it's ~25% of the Pi 3's power). I've also noticed this, albeit to a much less degree, on how smooth things play on my Pi 3's as well.

There's several topics which mention this from different people if you want to look around - I'm sadly one who always complains (and then am told I'm the only one and if it happened to more people - since the RetroPie image has been downloaded over 500,000 times - that more people would be complaining....OR that it's an upstream problem that has nothing to do with RetroPie)....so I don't know what to tell you besides to stay with 4.1 for the foreseeable future.

@IronAvocado 4.1 (afair) had a bug that the dynamic recompilation was disabled by default. It was fixed with a a binary update. It's worth testing with the core settings on 4.2 switching this setting on / off. I don't see any other upstream changes that should affect performance but I will test.

No it hasn't. Everything has not been slower. There may be some issues on some emulators, but not everything (and I need real test cases, not generalisations).

I'm getting a little tired of you repeating this -when there are reproducible performance issues they are looked into. You were the only one reporting slowdowns with that particular emulator (fceumm as I remember), and I was unable to see any significant/noticable performance decrease when I did some testing. The quicknes emulator is a better fit for the zero anyway. There was some alignment code changed in fceumm, but I tested with and without it, and it seemed the same.

Other issues that multiple people have reported have been fixed. CoolCV which was due to an SDL2 bug. a previous lr-pcsx-rearmed performance issue due to an error in an upstream commit (which I fixed).

@BuZz
BuZz, you know I appreciate what you and your team do, right? - and how I've said that numerous times before because I mean it. Take that as the truth please. And that's why I'm still on here posting (hopefully helpful) things when I can.

My only complaint is how I follow the scientific method with repeatability to the extreme (you've read the type of tests I do on multiple hardware, multiple computers, multiple setups all the way around) - and can reproduce every single one of my problems on like 6+ systems (which I've literally done), yet still get told it can't be reproduced...then read about other peoples same issues on the like 10 different forums I'm on...

But anyway, I'm giving up on this pursuit, ok? You have my word. Not another word has to be said about it– as I still want to be welcomed on this forum and not be shunned and not get help when I need it. Fair enough?

/end rant/end thread crapping

[BuZz]

@Dochartaigh

It doesn't come across as though you appreciate it.

Regarding performance issues - You tested on multiple machines, but you left out plenty of configuration details, and I was unable to reproduce - perhaps you can provide me with two minimal images illustrating the problem (on another thread - of course, don't include any roms).

I've certainly not seen many people on here reporting the same issue as you, and often issues are totally urelated- I need to be able to reproduce an issue to fix it (or report it upstream).

@IronAvocado please can you post your /opt/retropie/configs/all/retroarch.cfg and /opt/retropie/configs/psx/retroarch.cfg (use a code block - http://commonmark.org/help/ - or external pastebin site)

[BuZz]

I just tested with those core options on my RPI3 development set-up.

800x600 video, no overclocking, retropie 4.2

road rash plays smooth, and retroarch shows a pretty constant 60fps.

So must be something else different with your set-up

(I'm going to test building from source also). Did you try re-installing the emulator from binary ?

[BuZz]

Still 60fps when building from source too.

[BuZz]

@IronAvocado Please also post your /boot/config.txt and the output of uname -a

[IronAvocado]

@BuZz

I thought I knew what I was doing but I guess not. When I try to open either of those files I get a permission denied error. Are those the exact lines I need to enter on the command line? Thank you for your patience, I'm pretty stupid.

[IronAvocado]

@BuZz

Pretty much confirmed that I'm too stupid to handle diagnostic work, sorry Buzz. Everything I'm doing is returning permission denied errors and I can't get anywhere. I setup root access, logged in as root with my new password and I still get access denied errors when trying to open those files. The only thing I was able to get a result from was when I ran uname -a

Linux retropie 4.4.50-v7+ #970 SMP Mon Feb 20 19:18:29 GMT 2017 armv7l GNU/Linux

Will probably wind up doing more damage to the pi the longer I continue down this path.

@IronAvocado use sftp to copy them off or use cat to output them directly.

BuZz, most every time I talk to you I've used a crap-ton of smiley faces, "LOLs", and joked around to let it be known how light-hearted I take all this (even despite being in the middle of problems I can't solve...which can be extremely frustrating) . I don't know how else I can convey positive thoughts towards you and your team over the internet...you either believe me or not.

Me posting letting another forum member know they're not alone, not going crazy, that I've experienced things exactly like they're experiencing, and consoling them with the only bit of advice I can give them: to stay on 4.1. - isn't ALL negative if you look at it from that perspective, is it? (it's worked for me....for the most part my 4.1 images are running great!). And granted, I probably harp on my past bad experiences more than I should - sorry, I will try better to just let it go! lol.

The last time I was asked for in-depth details I posted a 46!!!! (forty-six) line-item description of EXACTLY how I set everything up on my systems to help troubleshoot for example…

Even on my last problem with overclocking I did all those AikonCWD benchmarks you asked for, and testing and posting all the Linux kernel? versions the different RetroPie versions use, AND posted those results and all...(I never heard back from anybody adter that....but that's fine, that was around the time I decided to give up on overclocking the Zero anyway...

I would say (besides running out of time on occasion - but to be honest more than likely just giving up after spending so many hours with no solution) that I've spent more time relaying information on my exact systems, tests, things I've tried, etc. than most other people on here. Hell, I won't even post about a problem until I've duplicated it on two or three different systems...

P.S. Feel free to erase all these posts - there's no PM system here which these would be 1000% better suited for, but just wanted you to see my reply - and I'm sorry for crapping up this topic.

@Dochartaigh you saying things like "everything after 4.1.5 (or there about) has been much slower" is your usual hyperbole and totally misunderstanding what retropie even is. pcsx speed has nothing to do with how one NES emulator was apparently slower for you, or whatever it was.

i've also asked you for information before and after having you crap up multiple threads moaning about an issue that you and your 97 cousins have had with their identical retropie zero systems.. https://retropie.org.uk/forum/topic/6264/you-have-to-use-identical-controllers-for-multiplayer-games-please-prove-me-wrong/6, only to be met with silence.

i'm teasing, but it is tiring. the 'retropie team' is likely just buzz and his free time for these kind of issues. the moment anyone brings hyperbole, demands or attitude to their requests, i often tune out. i read that sort of thing in much of yours. this is supposed to be a fun hobby for everyone.

Yes, that was one of those times, that after somebody made it abundantly clear that if my "crappy controller doesn't have any unique identifiers", that what I was looking to do was a lost cause, so why would anybody in their right mind still continue to pursue that if it's impossible? So I stopped. (p.s. that quote was from you, FYI :P

And dankcushions, I know it's tiring. Don't you think I know how tiring it is? Do you know how many HUNDREDS of hours I've tried getting this program to work correctly? How tiring do you think it is when I can repeat, over and over and f-ing over and over and over again, on multiple setups the SAME EXACT issues. Time and time again. To the "T". Identical results. Spreadsheeted numbers, error codes, FPS rates, version numbers, etc. etc. of results. No matter what brand SD card, what controller, how many brand-new Pi's I try, what 8 different USB hubs I use, etc. etc. etc. the same MULTIPLE problems keep coming up (which I've posted ALL over the place here and elsewhere, hoping, dreaming, wishing for a solution to any one of them), and the same reply (in essence) I get (most) Every. Single. Time. is "nobody else has this problem, therefore it isn't really a problem, you can't be helped". ...even the rare times I cross-post about other people I see with the same/similar problem it's still somehow not a problem to be solved...(bigger fish to fry - I get it). It's just tiring...that is also why I give up (like the above topic) if it's a lost cause...(and is why I'm still on 4.1.0 since it gives me the least problems).

Yet I still truck-on. Still post where I can with my small amount of knowledge if it'll help some other people. I am very sorry (honestly) if it bugs people like you and BuZz when I on occasion vent by reiterating my negative experiences I've had with this program. I will try my best (from here forward) to not do it again, ok?
