12.6. How do I speed up this DOS game?
The first time you try running a "standard" DOS game, it will try to run in a window on your desktop. Type ALT-ENTER to switch it to a full screen. To fix that setting in place, bring up the program's properties, hit the Screen tab, and set the screen usage to Full Screen. There are other screen controls here: "Fast ROM Emulation" works if the video driver emulates its BIOS in protected mode. Newest drivers from Cirrus Logic, for example, emulate their BIOSes in 32-bit DLLs. Try turning it off if you can't get VESA games working, though a properly written Win95 video driver should emulate VESA video modes in protected mode. "Dynamic memory allocation" specifies that Win95 will grab system memory as needed to update the game's display. Try turning this off if the display jitters, or the hard drive goes crazy as the display updates itself.
