One other note: You cannot operate the Vive HMD without jamming the system into full speed mode. It seems the default raspberry pi 3b+ CPU Frequency is 1.4GHz, and the core is 400MHz. The core really should be higher.
Add
core_freq=500
sdram_freq=600
sdram_schmoo=0x02000020
to your config.txt
and then at boot...
vcgencmd hdmi_timings 2160 1 40 20 46 1200 1 28 2 234 0 0 0 90 0 297000000 5 && tvservice -e "DMT 87"
echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
You can measure performance based on char here: https://elinux.org/RPI_vcgencmd_usage
More FYIs - I am trying to use the X thing since it seems with the frame buffer all draw calls take 30+us.
Install libgles2-mesa-dev cmake libglm-dev
Use raspi-config to install full kernel acceleration.
Any update on this? I got a dual OLED HDMI display and I can get them to do 1080x1200@90fps on a Raspberry PI 3B+ but once I try to go to 2160x1200@90fps I only get half a screen. I assume it cannot be done but is there a device with a similar form factor that can do it?
