+Yoink may or may not be playable with acceptable frame rates without a hardware
+accelerated OpenGL driver installed and working, depending on how fast your CPU
+is. Yoink is really not all that heavy on graphics, but it doesn't take much to
+overload a software implementation. If you're stuck without hardware
+acceleration, there are some things you can do to get better frame rates, in
+order of effectiveness:
+.TP
+1. Decrease the resolution.
+Use the
+.I videomode
+option or just resize the window if the
+.I fullscreen
+option is false and the
+.I resizable
+option is true. This speeds up software renderers considerably.
+.TP
+2. Decrease the timestep.
+Use the
+.I timestep
+option. You can set the timestep to be as low as the your
+.I maxfps
+option, but it is not recommended to set this lower than the target frame rate.
+Remember the trade-off here is decreased simulation accuracy. Try this to set
+your frame rate to 30Hz and your timestep to 60Hz:
+.PP
+yoink maxfps=30 timestep=maxfps\\*2
+.TP
+3. Decrease the level of rendering detail.
+Use the
+.I detail
+option. The game world may look sparse or incomplete, but that may be better
+than choppy animation.
