Emulators running slower for unknown reason
-
NESPi is a lovely looking case but ventilation is virtually non-existent. I had to drill a hole in the back on mine. Also that case makes fans sound really loud, it has the worst accoustic design ever - it doubles as an noise amplfiier :p
On Pi3 you definitely need to use a heatsink because it runs quite hot and the CPU throttles regularly without cooling. Be sure to use really thin (usually white) thermal tape, if it's more than .4mm thick it will make things worse.

I put the old sd card into the fresh Pi, and the games still stutter. So I can rule out the Pi itself as the culprit.
Good you found this conclusion. I was wondering if my pi suddenly died. I think I'll test tonight.
In my own situation, my pi is placed in the official pi casing, with the top off, like this:
I haven't changed this in the 6 months I have tinkered with it, and games stutter when I launch them, 1 minute after bootup. So even though active cooling could be nice, I don't believe this suddenly is the problem.

@megatimx
Are you talking about the Memory Split option in Raspi-config? If so, It's set to the same thing on both Pis. (256) -
No issues here, as I've posted in: https://retropie.org.uk/forum/topic/14756/retroarch-1-6-9-update-slowing-emulations-down
I did not try gba but the rest are fine. Messing around with the config will cause problems. They are already optimized.

You have to try a clean, updated, UNALTERED image to verify it's a config problem.

@darksavior
What do you mean? I've set up a fresh retropie image on the other card, and that one is working smoothly. -
@Slimy odds are a config was screwed up in the update since so many seem to be having this issue. I know it sucks but id recommend a clean install to the sd card that's giving you issues since the other one solved the issue

So, I've reverted back to RetroPie 4.3 and Retroarch 1.6.7 and can confirm that everything is back to normal again.
I then updated only Retroarch to 1.6.9 again (RetroPie still 4.3) and everything is terrible again. Armed Police Batrider stutters even in the menusounds.
So... Fresh install or should I just stay with 1.6.7 and wait for a fix?

YOu can check if it's the temperature by logging on the pi while you game using ssh and checking the temperature with this command:
/opt/vc/bin/vcgencmd measure_temp
If the temperature is below 70 degrees, it's not the temperature.
You could do slight overclocking but have you tried with another microsd? Microsd going bad can sometimes load and make gameplay stutter. Happened to me a while ago. FOr the slight OC, don't overclock and CPU but you could add some memory to the GPU.
Also, does it happen on demanding emulators (like n64) or even on nes and snes. Snes should have zero problems with a stock pi. If it stuters there, you might have a bigger problem.

...but if the pi overheats within minutes of bootup, I suspect the software to be faulty, not the pi. Edit: just checked. It's 56 deg C after bootup.
Microsd going bad can sometimes load and make gameplay stutter.
But as I stated above, I just tested with the old software on the same microsd and it's all good..? After the update, it goes bad again... So the microsd is not the problem..
FOr the slight OC, don't overclock and CPU but you could add some memory to the GPU.
Again, if I can run everything neatly with the old software, I don't want to overclock just to run a newer software better...? I suspect the problem is the software then, and then I'd rather stay with the old software...
Wouldn't you agree?

The temperature is below 70 degrees on bootup, and stayed there after running some games. (They were stuttering regardless of temerature.)

That sounds like a good test but I don't have another spare. At this point I'll probably switch to a clean install, though it would have been nice to know what went wrong. (If it's still stuttering after that I'll know it's the sd.)

I believe every system is affected, but it's most noticeable on the snes, gba, and psx.

on what emulator? mame2003? if so, that's had daily driver updates in the last few weeks and they are all untested, so who knows what's going on with that at this point.
-
@dankcushions I had a feeling they were not being tested but is this verified ? The libretro project is quick (too quick imho) to accept changes to cores, and in this case it seems unwise. It seems like a bad idea to submit untested backported changes to such a popular emulator.
I am considering forking and rolling back our mame2003 due to all the problems being reported.

Sigh all these claims about being "untested" are plain
[removed]every code change i've done has been fully tested on the MAME side by myself and if i broke anything
eg SEGA, Mortal Kombat sound or Batrider game speed i have fixed or attempted to fix the problems the guy should test batrider again after my recent commit
and see how it plays. -

Right ok it's not a playground i'll watch my language, but when multiple claims are made incorrectly that i've not tested my code it's not
exactly having a bad attitude to state my case here. -
@gamez-fan It looked like that previously to me, but happy you are testing - I stand corrected. You are welcome to state your case and correct things - in a manner fitting for a public forum like this that has users of all ages etc.

Yeah fair point i'll take it on board.

In this thread I can confirm that my issues are gone after a simple .cfg file deletion and regenerating.
