3.856000  [EMERG]: Sorry, your graphics card or graphics card driver is not 
supported. Please try to update the most recent, official driver
3.944000  [EMERG]: Error initializing ui::Manager: Graphics card or driver not 
supported

Even with updating the drivers, my video driver would not support the extension 
required, considering that ultima online was a low-end machine game, it would 
be good if it can run on those low end machines by lowering the hardware 
requirement through an option or a config file, so one can remove whatever it 
doesn't really need for playing.

Which computer are you running fluorescence on? Windows, Linux? Which graphics 
card are you using, and which driver? (There is a known problem with the 
nouveau driver on Linux)

This message does not necessarily mean that your hardware is not powerful 
enough, but is due to a check for the opengl extension GL_EXT_gpu_shader4 that 
is used in the shader. It could probably be rewritten to not require this 
extension, but as it provides some very basic additions to the shading language 
(e.g. proper integer support) I thought it was available on most computers 
anyway.

Sorry for the laaaaaaaaaaate answer, anyway I tested it in three windows 
machine and in a linux machine, except for one, that mounted a NVIDIA capable 
of shading, the other video cards didn't have the shader so weren't capable of 
running it, since the opengl driver wasn't updated for what was necessary, the 
NVIDIA one instead had the necessary driver, almost same machines, but only 
video card different.

The three machines were one SAPPHIRE, one ATI RADEON (I know, it's old, but 
that was for testing purposes), and a little netbook that doesn't mount any 
significant video card. The linux version was run on the ati radeon portable 
computer. Don't ask for specific video version, and I guess I should re-test 
now, if you changed something specific to this functionality in the meantime.
