However, before you dip in and purchase you have to verify card voltage.

For example
LT4 Mediators are 5V only and need 5V PCI cards.**
Mediator TX with an ATX supply can use 3.3V and 5V PCI cards.

** you can modify 5V mediators to support 3.3V Cards There are various modding threads here and there on that.

Should be any time now. There was a small delay in printing the Boot Floppy labels - the printer wanted a higher resolution image so we had to send them a new graphic. Once AmigaKit has the stock in hand I'm sure it will be on their site for immediate ordering.

If my memory doesn't fail me completely I seem to remember that the BVision only could be clocked up (from 90MHz) to about 97MHz on most systems which will only give a marginal speed increase, but it will instead get really hot and the GPU can actually unsolder itself from the gfx card (I've heard) without adding a proper heatsink as well (it doesn't have one).

I don't see a point messing and risking this without no real advantage.

Permedia 2 can not unsolder itself at that temperture ie around 170 to 190c the chip would stop working see PDF doc.

all Bvisions have 100Mhz SGRAM and can become standard if a long test is done,but i don't test at this freqeuncy i test beyond this.

a mandatory heatsink & fan is needed along with another small modifcation....

*remember* SGRAM chips are not overclocked @100Mhz.

@amigakit

Congratulations. This is a cool project.

Hammer D

Great work. Thanks for all your efforts.

How do you think os 4.1 will run on a desktop a1200 w/bppc and blizarvision and 256mb ram?

@realize

Thanks.

I haven't tried it yet with my BVision, but on my A1200T with Radeon 9250, with Warp3D hardware accelerated features switched on, it performs very well. I am running 128MB RAM.

I was just pointing out the required tooltypes to Delshay as he has a self modified BVision that can work at a higherclock rate. From another thread he said he could only use the higher clockrate with CyberGFX not p96 and was curious if the same could be done under p96.

Very well.
Like AmigaKit, I only run it on a Radeon now, but several testers had BVisions.
You won't be able to use the Hardware compositing features of Workbench, but there is a functioning beta warp3d driver included.
As you have a Blizzard you have the full 256MB of RAM available so there are less paging demands on the system unlike the A4000 which has to start paging out to either a ZorRAM, DKB3128 or supported harddrive after the 128MB on the Cyberstorm PPC is used up.
The extra 128MB on the Blizzard comes in handy for OWB with several tabs open.
As stated in the press release a new scsi.device may be available in update3 to allow paging on to a SWAP partition located on the internal IDE port of the A1200 or A4000.

I beleive DarrenHD posted some paging benchmarks in a earlier thread.

I don't have a BVISION anymore. I dont know if 4.X supports these p96 tooltypes as I've not tried to use them.

i think i already try this and it did not work on OS4.0. under cybergraphx the Bvision driver was modifyed so i can type any frequency i like,this was just a small modifcation.

perhaps a modifyed driver for the Bvision does no longer work via the tooltype,but if someone knows how to modify the the driver as least to a fixed frequncy 100Mhz under OS4.1 i should be able to find some time to test.

@all

Warp3D fo AOS4.1 classic developped (or updated) by Karl Churchill ?

(From the hyperion blog warp3D movies on classic).


- Who is this guy ? (New to me, for me another guy has updated warp3d...)

- He has also updated the AOS4 PPC for SAM and A1 version ?


Of course, i'm really curious about the improvements

@Mrodfr

He made the permedia2 warp3d driver, I don't think he has updated warp3d.

@Mrodfr

Its not update of whole warp3d, just a driver was released (which was done long time ago, and was in betatesting as far as i remember).

More of it, i think that this video just point out, that the whole OS can works much faster than in works now, and its not because of warp3d, but because of something else. Like many formid/permit() calls somethere, which disallow full speedup on other HW.

The KarlChurchill as far as i remember its Karlos from amiga.org. 5 years ago he help me with warp3d coding at begining, and he was permedia2 warp3d beta-tester and lately author. So i think that he just add some more fixes, and releas it at least.

OK. thanks for the informations

Runs pretty well. The 256MB ram will definately help you and the BVision gfx card works well with Warp3D (although the driver is in beta form still).

Throw in a Radeon PCI card on a Mediator and the Workbench feels even faster and you get the nice hardware compositing, not to mention the extra breathing room of more graphics memory.

But the BVision is pretty good, too. Would have been nice if phase5 put more than 8MB of ram on it, though.

They couldn't. The Permedia2 only supports up to 8MB of VRAM, so the phase5 cards were already maxed out as far as that goes.

If it more than that, then its 100% better ! When we talk with you back it times (5 years or even maybe 6? :) ) i was almost sure that all that bvision stuff will be never released. 68k version are not released through, but still.

Can you write some technical details about what was changed beetwen public 4.2 68k version of driver, and with new one for os4.1 ? Still interesting to sort out the stuff in head :)

Hmm, let's see. First of all, there were various changes required to make the driver work on Picasso96 and as things stand, there could be more to come. However, I am guessing that's not what you meant :)

All document drawing operations (points, lines, linestrips, lineloops, triangles, trifans and tristrips) are implemented for legacy V1-V3 API calls.
DrawArray supports all of the above primitive types too
DrawElements supports all the above primitive types and for all index sizes

Line width and point radius are not supported presently though. I'm considering the possibility of emulating it with triangle strips/fans respectively, but I'm not sure how much they are used since many drivers historically never even supported lines in the first place.

State management has been overhauled to reduce the amount of redundant register updates.

All vertex retrieval has been streamlined to state-optimised fetch routines. So, when you toggle any particular state or change vertex format, the driver selects a routine to fetch/process the vertex data that is optimised for that particular combination/vertex format. So, when you aren't using gouraud shading, colour coordinates are never fetched or translated since they aren't used. The code uses an indirect function call to achieve this so that the decision about which function to call can be moved totally outside the drawing loops and into the management code. The same strategy has been retrofitted even to the legacy W3D_Vertex based drawing routines which have their own set of state optimised fetches (only the state changes here, never the vertex format).

Access to the FIFO has been completely rewritten to be consistent throughout the driver and to reduce the amount of checks that need to be made.

Finally, as much as possible of the V5 API has been implemented which sadly isn't much but does include the InterleavedArray, combined buffer clearing and fog coordinate pointers.

There are still a few bugs to sort out, many of which I am aware of (and investigating) and some I doubtless aren't, but nothing that should cause any system instability.

There's a lot the Permedia2 just isn't capable of, though but the end result is that I can actually run Quake3 at a semi playable speed* on my A1200, which I never thought I'd see. And that's the old vanilla port of the game.

*depends on your definition. I tend to play PC FPS games so anything less than 60fps seems unplayable to me these days, but I remember completing AB3D2 on the same A1200 and that surely ran less than 10fps at times.
