what can i do ?

[chhfchhf]

i have a question about parhelia.
how much is z-buffer of parhelia?16bit?32bit?
how can i switch the z-buffer of parhelia?

[Kruzin]

24bit.
And it cannot be changed to anything else.

[chhfchhf]

24 bit,does it enough???

[Maggi]

imagine a UT/Q3 map that has a (virtual) dimension of 16 kilometers (~10 miles), using a zBuffer of 24bit can divide this space into 1mm steps, which seems pretty much enough for me ...

[Ribbit]

Yes, 24 bits seems like enough for everybody (haha, where have I heard that before? ). But why is the P fixed/limited at 24 bits? I thought the G-series were capable of using both 16- and 32-bit z-buffers.

[Jon P. Inghram]

It's gotta be capable of 16 bit z-buffer, otherwise applications that didn't support 24 bit would looks all funky. I used a hidden registry entry to force 32 bit z-buffer on my G400 MAX, and programs that expected a 16 bit buffer looked rather odd to say the least.

[Ribbit]

I remember Flanker 2.0 wouldn't work at all if I had '32-bit Z-Buffer' selected in the G200 driver options.

So is it better not to force z-buffer ? ie let the card auto detect ??

[Nowhere]

I haven't even checked the box "use 32-bit Z-buffering" in G400 driver options...and all works ok.



Oh wait, almost forgot, no games for a long time

[Jon P. Inghram]

That checkbox ENABLES 32 bit z-buffering, it doesn't FORCE it.

[UtwigMU]

I have enabled 32bit Z buffer for both cards in my box (G400 and Millennium PCI).

[chhfchhf]

why does matrox forbid to switch the z-buffer?

[Nowhere]

Jon P. Inghram, EXACTLY - when it isn't checked, applications can't use 32bit z-buffer
and I'm happy with that...

[Jon P. Inghram]

I used to play Everquest, and with just a 16 bit z-buffer you'd get visible depth artifacts on distant polygon intersections, like shorelines. And since EQ didn't (at the time) allow you to force a z-buffer depth I had to use the registry entry to force the depth buffer to 32 bit.
