+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:
+.TP
+1. Decrease the resolution.
+Use the
+.I videomode
+option. This speeds up software renderers considerably.
+.TP
+2. 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.
+.PP
+On the other hand, if you already get high frame rates, you may also want to cap
+the rate so that your computer doesn't do more work than it really needs to.
+You can get reasonably smooth animation at around 30fps, but you can probably
+tell a difference between that and a higher rate like 50fps. The latter will
+look noticeably smoother and nice, while the former is just "okay." See
+the
+.I maxfps
+option.
