- In order to summarize a few things about RISCOS 3.1, here is my
- posting about 3.1.
-
- During the last couple of days, I have e-mailed with a few
- people from Acorn about RISCOS 3.1 & ARM2.
-
- - Built-in applications, such as !Draw, !Edit and !Paint are faster,
- because they are in ROM.
-
- - If you are using outline fonts, things go much faster. Acorn please
- confirm has RISCOS 3.1 12 built-in fonts (RISCOS 3.0 contained only
- 3 fonts).
-
- - The desktop in RISCOS 2.0 was sometimes slow, if you were doing some
- time-critical things. I am using a counter (hour/minutes/seconds/milliseconds)
- in a window in my MIDI sequencer. This is already (in BASIC/ARM code) a little
- bit painfull. It takes up too much desktop bandwidth. If Acorn has changed
- the redraw methods and the construction of the windows. Thus sprites instead
- of the BFONT/rectange fill method, things are much slower. If for instance, you
- move a window, and the counter must be running at the same time, the counter
- may completely stop. This means that animations in the desktop are too slow.
- Acorn is Meastro still working fine ? Has Acorn changed the construction of
- the windows, because of the High-Resolution window borders ?
-
- - If you accessing files or doing some other filesystem tasks, the filer
- gets high priority. On ARM2/RISCOS2 machines you had to wait till your
- drive had done the job, so I think ARM2 users will still wait till the
- filer has completed its task. If you are formatting a floppy, and moving
- some windows in the desktop at the same time, I think you drink a cup
- of coffee and just sit and wait. To be honest, you can always turn the
- multi-tasking filer off. Besides, this I think that ARM2 users are no
- "power users". Thus while their files are saved, they already doing
- some other desktop job. Power users are always in a hurry ? Has somebody
- tried to use a soundtracker program (ProTrack) and to format a floppy at
- the same time ?
-
- To my opinion, nothing has changed a lot. The only difference is that application
- writers have to be carefull when writing their code. Make things always as
- fast as possible and don't use clumsy constructions.
-
- Loek.
