Choosing RTG method (To all Z2 bus owners indeed)

[FrankBrana]

Hi

I have just got a CV64/3D for my 2k, 060@50, fast scsi 2, 128 fast, ethernet, ide, scandoubler, etc etc

With my previous picassso2 card i was using picasso96, but I have heard CGX will be better for the new RTG and even that CGX has somewhat screendraggable feature(?!)

What do you think? CGX or P96 for the CV64/3D in Z2 mode?

I also heard that using some unknown for me MMU mode in CGX will speedup RTG graphics a lot. What about that?

there might not be a lot of hardcore A2ks outthere like mine, but there are a good bunch of 1200 Z2 boards. Guys, what tricks are you doing to speedup the thingie as fast as possible?

Thank you in advance

Frank

I have two A2K with Blizzard2060 and CV64/3D, I used to use CGX with them but went over to P96 because I have it on my Prometheus-machines and felt that the picture were much better and crispier with P96.

The only thing I can remember that would speed up CGX was the overclocking feature but I never did that because I hadn't got a proper cooler for it. I recommend a cooler on the board with original speed anyway, it´s getting pretty hot.

I used "Cyber56KHz" to get better sound and perhaps it did something with the graphics too, don't remember.

I'm using a A2000 with GForce 040 accelerator, and a Piccolo gfx card. With P96, there is a huge incompatiblity with WHDLoad-installed games, most installed won't work. With CGX 4, everything works, and the picture is as good as with P96.
But creating new screenmodes is under P96 much easier than under CGX.

BTW: a friend of mine has experienced problems in using P96 with the CVision64/3D in Z2-Mode. I don't quietly know what the reason was, he was using it in a A1200 with RBM-Board.

Better image quality in P96 than CGX?

Should I add a pasive disipartor on the chip of CV64/3D then?

I will try any kind of trick or patch that would speedup the thing a little

Thank you for your answers dudes

@analogkid:

Has someone released a better screenmode creator than P96Mode? CGXMode is really as easy as it gets and it is definately one of the reasons why I chose to use CGX when I had a CV64.

First of all you understand how to use CGXMode instantly, the gui is logical and clean.

Secondly, when creating screenmodes it has a really good predefined list of screenmodes (including vesa modes) you can choose from when creating new screenmodes. Moreover these predefined screenmodes shown are only the ones that both your graphics card and monitor can manage. What your monitor can manage is based on your selection of monitor. There is a rather big list of predefined monitors to select and if it is not there, it is just a matter of inputting the maximums for your monitor.

The third thing that is really handy is that you can actually move screenmodes around in the screenmode list (up or down) and change their order without recreating the whole list from beginning in the order you want it to be.

The fourth thing is that you can change all the timings to an exact number. Try setting the pixelclock in P96Mode to an exact number..

Btw, your friend might have had the problem that the CV64/3D in Z2 mode was dog slow - unusable even, much much slower than the graphics provided by the osc/ecs/aga chipset. It is resolved by running enforcer early in the Startup-Sequence for some reason I definately would like to know.

@Crusher:

There is no difference in image quality between P96 and CGX, the screenmodes must have had different timings. I must also add that the CV64/3D card in itself has a _really_ lousy picture quality - blurry, dark, bad balance between the colours etc. Lent my CV64 to a friend and got his CV64/3D to use whilst he had my card - what a difference, the image on the trinitron monitor looked like it belonged to a rather bad 14" shadowmask ! It felt like back in the days when I switched from a old S3 card to a Matrox card, but unfortunately the other way around. But ofcourse, everything is relative - I am sure someone is going to tell me that the CV64/3D does have good image quality .

I prefer to use CGX 4+, I find its much faster than P96
and it's really easy to create new screenmodes with it.
The testcard screenmode thingy is exellent, you can fine
tune everything, sync pulses and all.

I use Cybppc + CV64 in same machine (A4000).


Wol..

sorry Frank for this demi OT (maybe someone else interested) :-)

With the CVPPC (don't know with BVision) and CGX 42.7, there is an option "Gamma Adjust" in CGXMode>Monitor specification.

I've tryed to change values but nothing is changed or memorized.

There's a way to enable it?

Thanks :-)

@Framiga

No OT at all ;-D Anything amiga related is welcomed :-)

I have also heard that the CGX can be tuned to run in MMU mode, which seems to get a good speed boots at the grafics in general.

Anyone?

[analogkid]

It depends on your personal POV. Creating screenmodes in P96Mode is more intuitive for me than creating some in CGXMode, which doesn't mean that CGXMode is bad, it's easy to use and powerful, too.

About your ZorroII/CVision64/3D solution. Enforcer doesn't run on a 060, right ?

for testing I installed cgx3 on my system from the os3.9 cdrom... but what then? there is no screenmodes like in p96 to switch too... where do u change the screenmode to use cgx?
