I just tried running horde with 16-bit color assigned to my monitor, and noticed used it used different drivers. Here is the ouput from the log html:

16-bit:
Code:
Initializing GL2 backend using OpenGL driver '1.1.0' by 'Microsoft Corporation' on 'GDI Generic'

32-bit:
Code:
Initializing GL2 backend using OpenGL driver '3.3.0' by 'NVIDIA Corporation' on 'GeForce GT 240/PCI/SSE2'


This is on 64-bit Windows 7. I was just wondering if this is expected behaviour?

As far as I know, that's a problem of windows itself. If anyone knows how to workaround this problem, feedback is appreciated.

The obvious workaround is not to set your monitor to 16-bit colour. 16-bit colour has very limited support in modern drivers, and 8-bit paletted colour has been unsupported for ages.

Note that once upon-a-time, you could gain a small speed boost by working in 16-bit colour, but these days even if you do manage to get hardware acceleration in a 16-bit colour mode, you won't gain anything over 32-bit. The graphics card is still going to operate in 32-bit, and just round the final result before sending to the monitor.

Guess I'll just have to notify users to change it then. Thanks for the quick reply.
