Every emulator is running slow, exactly at 37 FPS

Post by Tatos_ » Fri Jan 18, 2019 1:12 pm

Hello everyone from Spain, it's my first time writing here. :)

I'm working on my first GBZ and I have noticed that every game, no matter the system or overclock, runs quite slows. By turnning on the screen FPS on retroarch I can see that all are running exactly at 37 FPS. That makes me think it's something related with some configuration file, but I have no idea what could be wrong.

If it helps by now I'm powering the GBZ by a 2.5A power supply and testing the performance through an USB keyboard. I'm using the New Gearbest Screen who doesn't require 5V mod. This are the changes I made on the default config.txt:

Code: Select all

framebuffer_width=320
framebuffer_height=240

display_rotate=2
sdtv_mode=16

arm_freq=1000
gpu_freq=500
core_freq=500
sdram_freq=500
sdram_schmoo=0x02000020
sdram_over_voltage=2

dtoverlay=pi3-disable-bt
dtoverlay=pwm-2chan,pin=18,fun=2,pin2=13,func2=4
Thanks in advance!

i would suggest to do a fresh install.....

and leave out or do NOT apply any over clock....
and defienately dont apply this...

Code: Select all

sdtv_mode=16


and then see how it preforms....

some times messing around too much with the config, will cause you issues....
but if you do want to add a lot of things...

add them one by one and test....
this way you may be able to see what things will work, and what things will start causing issues...

Are you running any additional code in the background? I had bad slowdown when using the MintyComboScript running in the background.
