Native Video vs RTG Graphics Cards

[tomekm]

I use 800x600 provided by Super72. By eliminating overscan I managed to improve the parameters to 27kHz/84Hz!!! The flickering is almost invisible... There`s other solution for CGX on AGA- CGX-AGA patch that can be found on AmiNet. I use it for years.. I have 040/40MHz and in companion with FBlit it works reaaaaly much faster than normally. Usng 256 color screen in not really comfortable for Workbench, but 128colors mode is several factors faster. I use 800x600, 128 colors for workbench and it`s really fast, because it is promoted to load images to fast ram, use simplegels and fastlayers. Few days ago i noticed that using Fusion wbwRefresh driver on my WB is t least 2 times faster than using any fullscreen driver! And all this on AGA... Using AWeb in this resoluton is comfortable, too.

If you want me to help you setup CGX-AGA in your system, please pmail me.

minimum of 30Khz? This has made me wonder if the Microvitec 1438,
1538, 1764/1701 can take video modes as well as SVGA. A handy range of
monitors to have!

Do you have a SysInfo module to demonstrate your graphics speeds at
800x600 on AGA? Sounds like a very slow system at 27Khz AGA.



ckillerh3 - If you can find a PicassoIV get that over a PicassoII, get the cheaper Cybervision 64 or
Cybervision 64-3D if you can't get the PIV. Maybe you could get a
PicassoII for less than 50USD though, it's a great card.

Cyberstorm: That ACK turboboard you mention sounds interesting - an
integrated GFX chip on an A1200 accelerator would rock. Busboards are
the bane of the desktop user! Hopefully if it comes out it'll be a lot
smaller and better ventilated than the PowerUP+BVision combo.

Also with regards to flicker fixers - they only seem to activate in
15Khz modes. It would be nice if they flicker-fixed anything that was
interlaced but they don't seem to do that. Multiscan:Productivity is
just passed through without being scandoubled or flicker-fixed.

I wonder if there is software for people using the custom chips to
make their own screenmodes like P96 users have. This would be great
for getting an LCD panel happy on a classic non-RTG system.

No, svga monitors normally do not handle 27kHz. I use Amiga M1438S to achieve this. As to speed: I use CGX-AGA and FBlit, and performance is very well (as for AGA, ofcoz). I will pmail you the performance test results from SysSpeed, when I make a module. If I haven`t forgotten, tomorrow.

P.S. U can also use ie. NEC Multisync 3D instead of M1438S. It is better because it`s a digitally-adjusted parameters display.

I think I'll try this Euro72 when I have a chance too... I doubt my
NEC Multisync will like it but I can try.

;-)

try it, it WILL like it:)
