Some models of the SiS 740 series of motherboard chipsets are equipped with a very low-end 3D accelerated IGP (integrated graphics processor).
The usual motherboard setup (not user modifiable) is to share system memory to video memory. This leads to very poor performance. Add to the recipe a lousy OpenGL implementation found at in their drivers, and you get a motherboard that '''can''' play Wurm without extra hardware, but with lots of rendering errors, ''most of the text missing '' and clumsy gameplay. This setup is ''highly unrecommended''.
Fortunately, these chipsets support an external AGP board and the motherboard manufacturers were keen on placing a AGP port on most motherboards equipped by them. If this is your case (check it out!), buy either a recommended ATI or NVidia card for a much better gaming experience.
