and also many big thanx from me for your great efforts!
I understand your suggestion not to buy any GFX cards in advance, but do you have a rough estimation about when you probably will have some testable version of the 2D drivers for the X1300 or X1550 available?
Hey, Hans.. this is quite a cool project. I havent been following it too closely. I didnt realise you had a driver in the works for current machines (using PCI cards). I thought it was for PCI-Express for one day in the future when new machines appeared.
What would the theoretical performance be like in 3d and games compared to existing Sam440ep's, and A1 AGP Radeons? How about Quake3?

Ciao
I really don't want to give an estimate since it relies on too many variables. Right now I'm still waiting for my computer to arrive in New Zealand. I sincerely hope that it will arrive in one piece and still be working. If it isn't working on arrival then things will be delayed until I can afford a new machine. Assuming that it arrives soon, I'm guessing that it will still take several months at least before I have something that I think is good enough to let others test. That, of course, depends on how much time I can spend on it.

Well, I'd have no hardware to develop this on if I had to have a machine with PCI-Express. Fortunately, a few manufacturers provide PCI cards which have integrated PCI to PCI-Express bridges.

I'd expect the performance to be better than existing AGP Radeons in general. The texturing speeds should be higher. However, the 2x AGP bus still has an edge when it comes to transferring vertices/texture data so there may be a few tasks in which that gives a slight edge. Typically 3D graphics speed is limited more by rendering complex effects than the bus bandwidth though, so the new cards should generally beat the older generation. Please note that the current Warp3D drivers for the Radeon cards aren't getting the maximum out of these cards; they can do better, but certain issues need to be solved first.
What I think is more important is that these new cards have proper GPUs, so fragment/vertex shaders and OpenGL 2.0/3.0 are a real possibility. Despite all the work that I've done on MiniGL, I can't wait until we can ditch it for a full MESA port. This is something that Radeon 7000-9000 cards simply cannot do.

I thought you might have been using a fancy convertor like the one olegil made and demo'd at a few amiga shows.

That all sounds awesome. Thanks for developing this for us. I'll stick to inserting strings into listviews for now.

I had a look at those, but they were too expensive for me. The PCI cards actually use the same bridge chip that those converters use.
Thank you to all those who voted. I had hoped that the number of votes would pass the 200 mark, but 151 votes does show a reasonable level of interest.
The model has been changed in Windows 7 to only hold the window images in graphic card memory. Apparently the penalty of copying back to regular memory wasn't that high.
Comments as it may relate to your P96 work? Does the P96 implementation hold 2 copies of the window image?

I can't really comment on the internals of Picasso96, but graphics drivers shouldn't have to worry about memory management stuff like this. The fact that they have to write new device drivers in order to support this change suggests that their original driver model wasn't the best.
To become betatester which graphic card should we buy ? and where is possible to buy a pci model ?
Any Radeon X1000 or Radeon HD series card that you can plug into your Amiga. I'm hoping that people will buy a range of different models, so that I can make sure that it works on all of them .
As for where to buy, I'll try to look up a few places and post links on my website later.
