Why do you think the Picasso IV "better" than the Cybervision?
-Slightly faster chip for 2D
-Faster edo ram
-Faster bus (CV3d is slower than both Picasso4 & CV64)
-24bit Flickerfixer (unlike 15bit cv3d scandoubler)
-Paloma&Concierto plug-ins
The Picasso IV is a Cirrus based video card, Is it's 2d acceleration faster than that of the the S3 verge in the Cybervision ?? does it have any 3d capabilities, How does it compare to voodoo 3 or radeon 9250?
Cirrus chip is slower than both Voodoo3&Radeon9250 and lacks 3d acceleration.
Yes you are correct, Both the Picasso IV (Cirrus Logic GD5446) and Cybervision 64/3d (S3 virge) are PCI bus chips and I believe both already have card PCI bridges in them.
IIRC CV3D used a vesa local bus version of the Virge chip but I may remember wrong. CV64 used a vesa local bus chip, that's for sure. What is noticeable is the slower zorroIII bus of CV3d against Picasso4&CV64
Has anyone actually benchmarked the difference video card and there performance on the 2-d amiga environment? AIBB perhaps?
There are old benchmarks in some webpages but you'll have to ask google :-)
What is the actual fastest 2-d video card for the amiga? This may or may not have anything to do with 3d performance or other features.
PicassoIV has fastest blitter and a quite fast bus (faster than cv3d, like most zorroIII cards). CV64 has faster bus. That's if we don't include PCI graphic cards.
As for a modern high end 3-d video card, they often lack or have reduced 2-d acceleration vs their 1990s counterparts. They depend on the CPU to do most of this work, which modern CPUs have no problems doing.
'90s gfx cards didn't have much 2d acceleration on Amiga. Blitter was limited compared to original Amiga one and didn't allow applying masks with different operations. Lines may be partially accelerated (but depend on software implementation). A few cards supported overlay. That's all AFAIK. On PC it depends on drivers too, and with Vista/Win7 3d acceleration is more important nowadays.
Anyway, you won't be able to connect a gfx card with weak 2d core to your classic in many years. AFAIK Radeons used today on OS4/MOS include full 2d core.
