[comp.windows.ms] Slowness of non-windows graphics applications...

yoon@aludra.usc.edu (Dae-Kyun Yoon) (09/08/90)

I have a question about non-windows graphics apps.

Whenever I run non-windows graphics applications in a full screen, the
speed of display is intolerably slow.  This slowness is more
noticeable in EGA/VGA mode than in CGA mode.  I tried every possible
combintaions I could in PIF files even I tried to modify time-slicing
in various ways, but ended up with no improvements.

Can this slowness be avoided ?
BTW, I run windows3.0 on 386sx w/4M and ATI VGA-wonder/512K.

I had the same problem on my 386SX; the slowness was so intolerable that
I had to exit Windows to run my DOS apps.  But when I acquired Crosstalk
for Windows, I no longer needed to multitask ProComm Plus, and I decided
to switch to Standard mode, which I had read was faster.

That was an understatement.  On my machine, an NEC Powermate SX,
Standard mode was noticeably and significantly faster than 386 Enhanced
mode.  Windows that crawled onto the screen now spring there.  And my
DOS applications run at least as fast as they did outside of Windows. 
(Norton SI reports a 15.3 outside of Windows, a 3.9 from a 386-mode
window, and a 16.1 from a Standard-mode window...I'm still trying to
explain that one!)

If you're running in 386 Enhanced mode, don't need to multitask DOS
apps, and don't need virtual memory (and the other perks of 386 mode),
give Standard mode a try.
