If anyone's is interested I just forked your Ullrich von Bassewitz's SVGA
BGI drivers on Github, and applied some optimizations and updates:

I hope using the FDAPM ADV:REG setting instead of
the FDAPM APMDOS setting solves the speed issue?

See the readme ;-)

It happens on both Virtualbox and my ancient Compaq NX-8220. And
indeed, as hinted by several folks, it seems to be connected to fdapm.

Sorry, but that is pretty much nonsense. All the drivers that I know 
used direct memory/register access, with the exception of the VESA 
drivers, maybe.


But that is in the very nature of the beast. If you try to be 
"cross-compatible", you have to make compromises. And those might result 
in a somewhat slower performance than specialized code, for one 
particular use case (hardware)...

It might be interesting only, if some existing project already relies on
these drivers.

The, probably better, von Bassewitz drivers are also under zlib license.

Is this real hardware or some emu./virt. environment?

is FDAPM loaded? in some cases it is reported to cause slowdown.

AFAIK this was probably in Borland's one, but I guess not the case with Jordan 
Hargrave nor Ullrich von Bassewitz ones.

BGI ran like a three-legged pregnant hippo in a mud pit, mainly
because it used the INT10h functions. Pretty much everyone I know, who
also started programming in the late 80s got their first taste of
inline assembler and hardware programming, when we realized that you
could speed up things by magnitudes by just vomiting your data
straight into the A000h segment. In fact I blew up at least 3 monitors
by fooling around with port-registers on my ridiculously expensive
Realtek 512KB SVGA card in an attempt to initialize the weirdest
256-color modes, like 734x412 and somesuch.

I still have legal copies of Turbo Pascal 3.0, 4.5, 6.0 and Borland
Pascal 7.0, so if there's interest, I'd be willing to take a look at
them to see if there's any insects to weed out.

Speaking of which. I noticed that pretty much all Borland Test-mode
IDE's for Turbo-C, Turbo Pascal and Turbo-Prolog react very sluggishly
in FreeDOS while working okay on MS-DOS and PTS-DOS. Anyone got a clue
what might cause this?
