One thing that surprises me, that while playing a DVD, and I launch say OWB-MUI to browse the net, the video starts playing slow motion or choppy. I have always expected video playback on the Amiga OS to be seemless. As I let the movie play it seems to get back on track but still, stimmys and stops...

No. It's hardware rendering. I wish that they hadn't used "3D" on that button in the GUI, as all compositing is done by the 2D drivers. It's causing a lot of confusion. Rest assured that the Radeon HD 2D drivers fully support compositing. Hans I saw your press release on the A-Eon mailing...

Done.

Thanks Hans. Yes- the 2D drivers work very well even with the 3D acceleration button checked to allow all of the fade effects - I take it this is a software rendering? No. It's hardware rendering. I wish that they hadn't used "3D" on that button in the GUI, as all compositing is done by t...

How functional are the drivers for the 4650? I cannot run Blender as I get a MinGL error. I am told I need to run Wazp3D which AFIK is a software CPU implementation of the 3D elements that would normally be provided by the hardware of the Radeon. Is this correct? The 2D drivers work well, as you sh...

With update 3 i got exactly the same FPS in general but indeed since update 4 it seems that if i start an application before starting Quake 3 or even ADoom (that don't use Warp3D at all) i got this huge slowdown like somethings still continue to use my CPU (or VRAM?) in background Again, what FPS u...

That's strange behaviour. Possibly the slow-down occurs because your VRAM is filled up and fragmented by the other apps that you have run. Why this behaviour would only occur in update 4 is anyone's guess though. The changes to Picasso96API.library are pretty simple, and I wouldn't expect those to c...

Correct, rolling back the rtg.library does downgrade the 2D graphics performance. That's because you're discarding all of the performance enhancements provided in update 3.

No. Some of the Radeon 9xxx cards have the 256 MiB is split between a primary and secondary PCI device instead of leaving it as one block of RAM. That's a totally different problem.

Is it possible to get AmigaOS 4.1 update 2 to recognize more than 256MB of memory on my 1GB Radeon RV710 (XFX HD 4550 graphics card)? No, it's not. The problem is that only 256 MiB is visible to the CPU over the PCIe/PCI bus; the rest is only accessible by the GPU. Since Picasso96 expects that the ...
