1. IMPORTANT TO ALL
TO ALL
when telling timings or rates or in this case
frames per second please state your machine specs.
Processor: Cyrix 686
Speed: 200 Mhz
Memory: 32 Meg
Cyrix 686 200Mhz I believe is roughly equal to a
Pentium 166Mhz...........NOT Sure.
TO RALF
You included frames per second (fps) BUT
you didn't state your machine specs.
I have a friend that has 486 100Mhz
with 16MB or 32MB of memory.
I have a Cyrix 686 200Mhz with 32MB of memory
Another friend has a Pentium 100Mhz with 16MB memory
What are your specs so that we can at least ESTIMATE
our speeds.
IF My 686 gets 1000 fps THEN
My friends 486 gets about 500 fps
BIG DIFFERENCE.
If I get 76 fps he gets about 38 fps.
IF yours is a Pentium 200Mhz and gets 75 fps then
mine SHOULD get about 66 fps to 70 fps HENCE
my friends will get 33 fps to 35 fps.
THIS means a 486 66Mhz will probably be to slow
Especially if it only has 4MB of memory.
I imagine that a machine of that spec. would get about
15 to 20 fps.
THIS IS IMPORTANT

True, it was run on a P-60 with 24-mb of ram with win95 loaded..
however the memory doesn't mean much unless you use more than
available, if you do so an dmemory could not be allocated.. image
type is loaded... so routines will still work but a bit slower
(2d-sequence screen is slower than memory-screen)

Not exactly... most is affected by cache & video-card, if you have a
slow video card it will go about twice as slow, for a pixel here and
there my video card seems to cache it too.. but for large things my
video card's memory is slower than real memory... although i guess my
video card is pretty quick, it's a Cirrus (PCI).
About the memory, when i start dos prompt in win95 i get about 20
meg free memory, while my quite windows swap file is about 50 MEG!!
The video things still require far more cpu then the rest of my
code... so the video card says more than the type of computer...
My father has an portable p-120 with 12 mb of ram, the racing game
Screamer runs in slow-motion, the inbuilt video support is SLOW
(with his and many other portables), this is my point here.
