Depends on what kind of bussboard you intend to run.

I found BVisionPPC to be faster than Voodoo3 on Mediator for example.

Bvision can run upto 1600x1200 but the screen is very fuzzy, so a graphics board with DVI is much better (I guess).

Im actually thinking of making a completely new cable by using shielded TP-cable, dont know how much improvement that would be though.

Orange: I was thinking of running double cables or even a single TP-cable for every signal comming from BVision.

Actually, while BvisionPPC *maybe* a little bit faster on desktop and video playback than a Voodoo on Mediator with 8mb window set, on anything warp3d Voodoo is much faster. And thanks to Voodoo's 16mb compared to Bvsion's 8mb, you have more space for opened screens.


While that might be true (which I have no reason not to believe)on most things on the desktop that moves, it is much faster on the BVision and sometimes slower than AGA on the Voodoo. For example EaglePlayer/Deliplayer graphic visualisers, scrolling in browsers etc, running a big shell screen you can notice that when scrolling large chunks of text. I dont remember the issues in detail anymore because I sold my Mediator so soon. But there were some topics about these issues on the Mediator mailing list without no known solution.

yup, that's true about the visualizers, but Browsers scroll very fast, my vinced and kcon shell are rapid as well. I guess some programs are coded in a weird way. Also, some ppl may have speed issues if they've set the memory window on mediator at 4mb. I've found out that, contrary to what the manual says, the window can be at 8mb at all times with a compatible accelerator even if a pcmcia is present. Sure, in this case there are glitches (ie in Shapeshifter), but even then there's always that nice "remcards" blizkick module to disable anything at the pcmcia with a reboot and keep the speed of 8mb without problems.


Well I tried both 4/8 MB to and did not notice any improvement. I can not claim browsers scrolled more smooth with the Voodoo, however I noticed if something moved in another window while I scrolled in a browser that window slowed down quite a lot.

That behaviour was not what I was used to in Workbench and I got quite annoyed by these problems.

I am curious if the never revision of Mediator (TX) has the same problem or if the A4000 variants of Mediator shares the same problems too, because I would love to have a rock solid 1920x1200 Workbench.   8-)

About cooling the BPPC, I would not remove that black heatsink and replace it with a single cooler over the PPC-chip because the original heatsink was meant to cool the chips on the side of the PPC. You will need some kind of airflow over these small chips if you remove it and if you study the original heatsink you see that it has a channel where air flow over the chips but only has contact with the PPC.
