- This is a bit of an oversimplification. First, although the amount of data
- that moves across the bus is greater for a SVGA than a monochrome card, the
- SVGA is likely a 16-bit card, the Herc is certainly not. Furthermore, the
- drivers and the hardware for most SVGA cards (even cheap ones) is optimized
- for the Windows environment. In most cases, a well optimized driver can make
- a WORLD of difference, and I'm sure that the Herc. drivers are not going to be
- all that well written, seeing that they are in low demand as a GUI device.
-
- In addition, there are several cards out, including the numerous S3 based
- cards (such as the Diamond Stealth, Orchid Fahrenheit 1280, etc.) and other
- cards (e.g., ATI's Graphics Ultra) that have a "graphics accelerator"
- included. The main difference between a graphics accelerator and a true
- graphics coprocessor is that the former has a fixed set of functions (such as
- BitBlt, filled rectangle, line and vector draw, hardware cursor, etc.),
- whereas the latter is programmable. You can pick up an accelerated card for
- about $250 if you shop around a little.
-
- I run Windows at home on a 20 MHz 386SX, and since installing an Orchid F1280
- card, it has gone from a barely usable cripple to a machine that rivals DX
- machines with faster clock speeds in how fast it handles the GUI. (Other
- things, such as multitasking, are still a little weak, of course.)
-
- I'd also like to add to the previous author's comments that more RAM can make
- a world of difference as well. I'd recommend 6-8 Mb, if you can afford it. 4
- is an absolute minimum for most applications.
