well...performance is not the whole world! but if we have 64bit-support 3dfx will enter a new level! we can use a voodoo in the future! with a 64bit cpu....and a 64bit OS! that's the future! and i guess everybody want to install a v5 5500 pci in a 64bit-system....boot winxp x64 and have fun...

i guess everybody knows this quote: "In this place all think voodoo..."

so don't be pessimistic and think voodoo!!!

(meditates and begins to float!)...LOL! But seriously, a 64 bit CPU would be beneficial as Voodoo's rely on the CPU to do calculations - and since ALL CPU's will soon be 64 bit, someone will need to test it soon! 8)

yeah I was thinking in that kind of direction, look I don't have the brains to program but there are some idea's floating around, and when one idea get's in the way and I'm not so sure I will post it here hehehe

but Voodoo5500 you do have a point, the Voodoo5 5500 AGP does 5.4 GB per sec and 667 - 733 MP per sec, that's how 3dfx once said it, but indeen OC'ing isn't that helpfull either, okay the card has that as it's max, but I'm still quite confident that if the CPU can do 40% more of it's original output in 64Bit mode that Voodoo5 will move along with it, because otherwise the whole system won't get a 25% overall improvement.

Sorry I'm not so mathematical though . Undecided

As I said, the CPU power is irrelevant at current levels already.

The Triangle Setup of the Card itself can only handle this much.
Even if all T&L was performed on a Quad Dual Core Opteron in 64bit, the performance would remain almost identical, since the Card can't go any faster than it already does.

I'm afraid there is no way to bypass this bottleneck, since this is hard-wired in Silicon, no workaround possible.

My own testing has shown me that on my amd cpu's the performance gains stop at around 1700 mhz in 640 X 480 resolution.

Running one of my pci models on an athlon 64 3400 @ 2400 mhz gives me almost identical scores unless I overclock the card Wink

Speaking of overclocking, I have 2 pci models, one has Hyundai ram that runs @ 185 mhz very nicely, but my other has Toshiba and has run a GLExcess demo loop for 4 hrs straight with no problems @ 200 mhz stock cooling Grin

, so much for the theory that only the ones with Hyundai ram have some overclocking potential Wink

sorry guys, but somethings are hard fgor me tyo relizes at some times, but I understand now, I suppose my brains wern't funtioning propperly hehe, and taht for a Jedi Master hehe. Shocked

But yeah i see the logics now, OC'ing would be the only way out to a higher speed, but even that has it's limmits.

Thanx everyone for the help, The Force Is With You all, I can Sense that Wink

I have observed similar behaviour with my cards.the performance hits its limit with a CPU around 1500-2000MHz.it simply wont go any faster after that,no matter how much CPU power do you feed it..

In order to produce a "64-bit" compatible 3dfx driver for the next Windows OS, there is not as much work involved as you would expect.

Due to underlying 32-bit support for existing software to operate on a 64-bit CPU, the whole software design does not need to be re-structured to such algorithms as multi-threading.

Instead, we only need to reconfigure the read header of the driver, so that it recognises the hardware through the new OS.

Re-designing Glide is another matter. In order to adopt Glide into modern games that are aimed at the new 64-Bit OS' (but this will never happen), Glide would have to be re-structured to use 64-bit architecture. However, this is really not worth the effort, and we would just have to rely on 32-bit support for our old games that already utilise the Glide API.
