Reply To: Random Roms Running Slowly

I have the same problem since one month. Retroarch runs slower with threaded video. Seems to be a library problem. If i use older userland libs (https://github.com/raspberrypi/userland/) threaded video is faster and there is no audio stuttering.

If i checkout the following commit everything runs as expected:
https://github.com/raspberrypi/userland/commit/5e67fb321c0ec308e6cffc4f2ef1668fcc8e9250

1. delete or rename directory /opt/vc
2. install old userland libs

export CFLAGS=" -march=armv6j -mfloat-abi=hard -mfpu=vfp -O2"
git clone --depth=0 git://raspberrypi/userland.git
cd userland
git checkout c5749b99f2
sudo ./buildme

Be aware that rpi-update overwrites /opt/vc
