Hi,
Yes that does work, I think that is the default option if you pass no
parameters isn't it?
However, The program does not seem to be running with hardware acceleration. I
say that because it runs the same speed when I run it with --dfb:no-hardware!
It is also the same speed as if I run using the vesa frame buffer (/dev/fb1)
which does not support acceleration. I really wanted to get the GPU to do the
work.
