Like I said. Warp3D does not seems to be affected. Only direct access to the frame buffer.

Hey guys. Just a short update to say with Hedeon's help from 2000 miles away I've got a new board running-sort of. It's a little faster. Only some basic stuff running so far.




I'm going to call it "Ragnarok".

Adoom gave me a benchmark result of 51.83 fps.... at 800x600. 61.17 fps at 800x480. 640x480 gives nonsensical results.

GLQuake gives a disappointing result of 50.5FPS@640x480. But I have wide FOV as I normally run at 800x480, so maybe that doesn't mean much.
Quake2 65FPS which is not much more than my overclocked Rapture.
Gears 83.95fps at 640x480

Dosbox though.... seems pretty pretty pretty good.

Things are not 100% working yet.

Something else weird that I've noticed is that with my ScummVM 1.81 I can set 16-bit 44khz AHI Mode on my PCI card and it plays without stuttering now.
Also frogger.

Isn't that just a consequence of having a (much) faster PPC?

Well not really-I don't think so. The PPC isn't involved much when just dumping an audio stream to a 68k ahi device. Then if the output format doesn't match the AHI device, the 68k does the conversion, usually badly. Seems like there's something different going on with how PCI transfers are happening with these later cards.

I would assume Hedeon if he used a PCI sound card with his Sister-of-Rapture that has the same 7410 as the Rapture he would also see PCI sound working better, we'll see.

Quake 3 results are not so great at the moment either:
Rapture 37.6 fps Ragnarok 41.2 fps
With Bilinear, Vertex, Texture one step down from max, Geometry high.
I thought they were much better than they were at first but on the same demo on Rapture, setting Trilinear and Texture at high went down to ~30 FPS.
