[Chimera-users] chimera 1.11.2rc crashes

Hello Tom

You were right.
I removed the Quadro graphics card and installed a lower spec card (GT
710-1G RAM).
Then started Chimera and did the same movements. Chimera did not crash but
the card was struggling to cope.
Rotating a structure with added maps was quite slow. After a while even the
chimera menu became slow.

Could you please suggest to me a graphics card that chimera will be happy
to "play" with?

Many thanks
