NTVDM.EXE on win 7 32 bit - new build (Emulation)

posted by RayeR Homepage, CZ, 03.07.2020, 12:57

Yes, this is expected. As you know in 64-bit mode you don't have accessible v86 mode. The NTVDMx64 uses softcore CPU emulation same as NT4 for DEC Aplha used to run x86 programs. But still by my test the DJGPP compiling is ~10x faster than under Dosbox. There is also NTVDMx64 version that can use intel HAXM virtualization acceleration but unfortunatelly intel HAXM is limited and don't support DPMI programs. Also even with VT-X the graphics emulation is still very slow at too many VMEXIT occurs during emulation. So it helps for some real-mode text based programs. I didn't try to compile it yet, it needs more depencies and I'm not insterested without DPMI support...
