Very poor performance under Linux

There's your problem. Dominions link to a different version of the OpenGL libraries than GLXgears do. Most likely the version in /usr/lib/ is the Mesa software-based version. I'm not sure how to sort it -- you can try to move all files starting with libGL under /usr/lib to a backup directory and see if that sorts it. It might cause some issues, in which case you'll have to copy the files back again.

Will try that. Nice to have an expert on board

I also notice that neither program depends on the libnvidia-tls library, so am I right in assuming that you haven't installed NVidia's own Linux drivers on your system?

Well, considering this laptop happens to have an ATI graphic card, this seems reasonable to me...
