TeXmacs is unusually slow while editing?
Answer. Graphics card drivers with poor 2D performance can slow TeXmacs down termendously. If you are running TeXmacs under X on a system with an ATI graphics card and are using ATI’s proprietary drivers (the driver called fglrx), you can achieve a significant speedup by • either running an X server such as Xgl that performs 2D operations using the 3D API of the graphics card driver, • or switching to an open source graphics card driver such as ati or radeon which have a far better 2D performance than fglrx. Note that if you try both at the same time, you will slow your system down even more, instead of speeding it up.
