Performance Problems - Raspberry PI 1 Model B+

melao

Hi Buzz, i will try your recommendations.

For the overclock, I used the HIGH settings on the raspi-config as below:

High   950MHz ARM, 250MHz core, 450MHz SDRAM, 6 overvolt

PSU, I used an Apple 2.1A charger and another 2.1A charger called fishbone, plus one Mi Powerbank that is able to pump 2.1A as well.

Fishbone (pretty cool! I recommend a lot!): https://www.kickstarter.com/projects/805339168/fishbone-charging-station-tidy-up-and-charge-up

Mi Powerbank (10000mAh): http://www.mi.com/en/powerbank/

Hi Buzz,

list itemlaunch the "configuration editor" and try lowering the "render resolution" for libretrocores

I launched ./retropie_setup.sh but I cannot find the render resolution anywhere

I was experiencing the same problem. It was solved when I changed the Overclock to Turbo (using raspi-config).

That's interesting. I use a Pi 1B without overclock and I've got no probs w/ the classic consoles (snes etc.) nor w/ Mame. I can even play Quake III Arena fine and Jedi Outcast runs quite well too, except when there are a lot of stormtroopers around. Only the newer consoles don't work.

@Meneer-Jansen Do you use your rasp1 offline? I'm thinking if this slowness is because of my wifi dongle...

I'm disappointed with the poor picodrive even with a Turbo overclocking...

Maybe, maybe not. I use my Pi w/ a wired internet connection. Wireless connection is very bad. My wireless dongle goes on an off the whole time. And I think it requires too much Amps. Power is always an issue w/ the Pi. Weird things happen if the Pi's under powered.

@Meneer-Jansen god dammit! You're right! I've tested picodrive with no wifi dongle and it runs smoothly!
It's unfortunate... I was trying to dedicate my raspi1 to be my RetroPie for earning RetroAchievements, and I have to be online for this...

Well... Thanks for show me what is the problem.

Glad to've been of help. :-) In the future you can chech if your Pi's in trouble (CPU wise) by logging into is via SSH (Windows: use PuTTY) and type the command:

top

If your Pi's running Emulationstation w/ NO emu active then the CPU load should be no more than 30% after a while.

"Unfortunately" the rasp must be connected to receive outside ssh connections. :D

Nevermind... I'll find another application for my old raspi1.

And thanks for the measure. This value (30%) is for a raspi1, right?

When I try to measure CPU load I disconnect the WiFi USB dongle and the Ethernet cable. The max load (when Emulationstation is idle!) is indeed max. 30% on my Pi 1B.

[edit: corrected typo in the word disconnect]

Meneer Jansen

Oops. I meant disconnect the Wifi dongle in my post above.

OK. It makes sense now. :)
You can edit it to avoid misunderstading for future readers.
Thanks for your replies. My rasp1 is running very well.
