Okay, Thank you forum a lot =) The BloodCM is awesome, but back to original DOS Blood and also CHASM.
UNIVBE Drivers seems helps to speed up. Also LFB is faster mode than Banked?
Also for some games DOS32A Extender makes them faster?
About Chasm: The Rift there is file DPMI16B.OVL seems this game writed on pascal, running CWSDPMI before game, makes error, "can't handle 16bit apps"
Where i can find DPMI16B.OVL i think if i find latest version of shared files it can help speed up.
Also there is QDOS with some interesting things
http://dk.toastednet.org/QDOS/
http://dk.toastednet.org/QDOS/FASTV110.ZIP -> Enable Write Combining and Linear Frame Buffering. Greatly speeds up Quake.
http://dk.toastednet.org/QDOS/MTRRLFBE.EXE -> by RayeR -- Faster video modes under DOS.
Both not works under dosbox even with combination of UNIVBE
But any way authors is managed to speed up video under real dos. So its possible under emu too.
They writed a way mre faster algorithm of transfering data.
I am still believe that it can done faster.
