The black icons were designed for us by the talented icons guru, Mason. We are very grateful for the hours of work he devoted to them. They will feature on AmigaDeveloper.com team releases including the forthcoming Enhancer Software.

I couldn' t find whether it is for free or not, any idea?

I bet it is commercial product. No release for free.

Then I am curious about its price.

I expect in the same league as Warp3D SI.

I'm not familiar enough with the R200 to give a breakdown of what it could and couldn't support. Some basic details: vertex shaders: - Up to 128 instructions long - Only 12 registers, and no memory access fragment shaders: - Up to 22 instructions Neither shaders can handle the full GLSL repertoire (e.g., the Radeon X800 can't do proper for loops, so I doubt that R200 GPUs can either). That's a lot of restrictions, and it's no surprise that ATI never released GLSL support.

Even ARB assembly was kind-of dodgy on R200, I hardly think anyone could write a GLSL compiler for it, even for the oldest standard.
The X1800 (R500) had a new architecture, and it definitely had a working GLSL shader compiler (although a very buggy one, thanks to ATi), so that could be a possible upgrade path for old motherboards. Plus it works with MorphOS too, for those who want to run both on a Peg2. Who wants to write a driver for it? :)

X1800 (R500) works in Pegasos 2? I thought there was firmware limitation for anything higher than R300.

I can sort-of understand the "obsession" with getting older Radeon cards working with Nova. But with the low user base and the actual developer time/cost involved an attempt to support older cards just doesn't make sense.

Provide a software/hardware bundle at a subsidized price. I suspect it would be much less expensive and more expedient to offer discounted up to date graphic cards than try to sink money into drivers for near-obsolete cards.

I have used a similar method to get some of my clients to dump old versions of server hardware. It was costing me $$ to keep supporting the development toolchain, porting costs, etc... Was better to just give the customer a deal on their maintenance to push them to upgrade. Everybody wins.

For users without PCI-e slots I provided a link to an adapter that may solve that issue, but it is untested as far as I can tell, so give it maybe a 50% chance of working.

Ooch, you are right. I forgot that these cards use PCI-e to AGP bridges. So much for having a least common denominator on the Pegasos.

I'd happily dump my Radeon 9250 if I had something else that works, but Pegasos II / Sam 440 / AmigaOne XE/Micro users doesn't have a lot of choice. Maybe adding a Radeon HD card using the PCI-e to PCI adapter as a secondary card could work? I know it does in PowerMac G5s under Linux. I'll have to ask Hans about this.

Currently only the Sam440ep-itx (with unreleased Uboot) and Sam440ep-flex.
Radeon HD 7750 card did not work when I tried with a Sam440ep-Flex 2 years ago.
May need a Uboot update. Cards up to Radeon HD 6000 series do work.

I was testing and using HD2400 PCI card in A1-SE years ago. But that model doesn't have Warp3D support.

Well done guys, this is a really big deal for the Amiga. Another step forward. Congrats to all involved.

Great work Hans, thank you!

If I am curious about how to write a program that uses this, but I'm not yet ready to ask for the SDK, what would you suggest I could read or study to learn about this?

GLSL is what you'll be using to write the shaders, so have a look at that.

Finally, The recenly passed Christmas saw my stock 4000 series graphics card replaced with a "R9280X". My music scrolls (fairly) smoothly towards the clef already. I wonder if (either)Warp could help me scroll more smoothly in 2D, or how a 3D option might affect the render?

Warp3D Nova can quite comfortably be used for 2D. There's even a mode that will disable frustum clipping and give you a plain 2D coordinate system (so no rescaling needed).

I agree with broadblues that CompositeTags() should be your first port of call with 2D, though. Use Warp3D Nova for effects/processing that the graphics library doesn't do.

Talking about 2D uses, here are two that I'd like to see:
- Accelerate AmiVNC by using shaders to detect changes on the GPU (so that only changed areas get copied to RAM
- Do the same for SRec, but also use Warp3D Nova to perform RGB => YUV420p conversion on the GPU

Unfortunately, the Pegasos II firmware doesn't look behind a PCI-to-PCI(e) bridge, so it doesn't even detect the card. If someone could get there hands on the firmware's source-code, then maybe this could be fixed. Fixing the firmware would definitely be easier than writing an R300 driver (which I think is AGP 2x compatible, and does *NOT* use a PCI-to-PCIe bridge).

Sam440 machines can use PCI-to-PCIe adaptors, but I've been told that UBoot doesn't like Southern Islands GPUs. Spectre660 will be able to tell you more.

As for the A1-XE/micro. I used an A1-XE without the DMA fix for initial development of the Radeon HD driver. No idea if it still works. The DMA fix (both XE and micro) causes lockups.

Yes, I also think that it would be less expensive.

Great, finaly a reason to get rid of my peg2 and buy a x5000.

Regarding the Radeon 9250, can it be used at all to speed up scrolling and video playback in browsers? That would be a very nice boost to have on any machine.
