Title: Voodoo 4500 and 5500
Post by: Iggy on January 09, 2012, 08:32:22 PM

I curious about these two cards.
What experience have any of you had with these (and under what OS')?

Voodoo 5 5500 PCI

Works just fine, OS3.9, OS3.1, OS4.1 Classic, tested on A1200 with Mediator 1200SX and A4000 with Mediator 4000D.

Warp3D works but you only get a minor speed improvment over the Voodoo 3 as only one GPU is used.

Only half the VRAM is used (32mb) this is the same for OS4.1 Classic which is a shame since you really could do with the 64mb, in an OS4.1 Classic setup I suggest the Radeon 9200/9250 anyway as these work with the hardware effects within the OS whereas the Voodoo works albiet very slow!

I use a Voodoo 4 4500 PCI in my Mediator on the classic. The Mediator P96 driver is for the Voodoo 3 but works. There are bugs in Big Endian screen modes that mess up the colors but no crashes and only 16 of the 32 MB of memory is added to system memory although all 32 Mb of gfx memory is available for P96 and Warp3D. The Voodoo 4+ supports more 2D screen modes if they would work in the driver. The speed is faster in some cases and slower in others than the Voodoo 3. Only 16 bit modes are supported by Warp3D although the Voodoo 4+ is capable of 32 bit and 15 bit 3D. Most of the advanced features of the Voodoo 4+ are not supported in Warp3D for the classic. The Voodoo 4+ may be better supported in AmigaOS 4.x but the Radeon makes more sense there. There is no Radeon Warp3D driver for the classic.

Thanks guys,
That was just the kind of info I was looking for.
I have a Voodoo3 PCI card and was always impressed with it.
To bad the 4500 isn't better supported.

I have a 3000 and 4500, in a Prometheus/OS 3.9 setup 3000 is the better choice because of the driver.

I'm curious. The Prometheus P96 driver should be totally different than the Mediator P96 driver but I wouldn't be surprised if Elbox copied portions of the Prometheus driver, including bugs and poor card initialization (Voodoo 3 emulation is quite good with proper card initial setup). What is wrong with the P96 drivers for the Prometheus when using the Voodoo 4?

Hardware acceleration doesn't work in several 2D operetions.
