What should it be set to? I want to try again.

And yes, it’s running on a Raspberry Pi 3 B (I think non-plus)
Maybe i missing something, but i found that OpenCPN hardware acceleration on rp 3b+ works for me only with

dtoverlay=vc4-kms-v3d

enabled in /boot/config.txt and "G1 GL" driver chosen in raspi-config (Advanced option->GL Driver)

OpenCPN works significantly faster but there one huge disadvantage for me: overscan/underscan options not working with vc4-kms-v3d driver, so i have black borders on one monitor or desktop not fit to screen on another...

one can test opengl with glxgears command. With fully enabled opengl it have to show about 60fps
I definitely also had the overscan issue that I wasn’t able to fix as usual!
On top of that, I could only select one resolution where without opengl I can select whatever I desire.
