Przy wyborze karty "na przyszlosc" polecam zapoznanie sie z opinia
jednego z tworcow bardzo popularnych gier FPP na temat przewidywanej
wydajnosci kart graficznych dla ich najnowszego dziela.
Wczoraj John Carmack z id Software oglosil plany wypuszczenia,
znacznie wczesniej niz uprzednio zapowiadana Trinity, gry Quake III.
Q3 ma byz zdecydowanie bardziej wymagajacy co do wydajnosci kart 3D.
Pozdrawiam,

PS. Tez jestem wiatraczkowcem - z tym ze nie uzywam dodatkowego
wiatraczka do chlodzenia ukladow 3Dfx Voodoo, a do oziebienia
kostki Rockwell w moim modemie - diabelnie sie nagrzewa :)
%%%%% John Carmack na temat wydajnosci kart 3D w Quake III %%%%%
Here are my current GUESSES about how existing cards will perform
[Quake III].
Voodoo 1
Performance will be a little slow, but it should look good and run
acceptably.You will have to use somewhat condensed textures to avoid
texture thrashing.
Voodoo 2
Should run great. Getting the 12 mb board is probably a good idea
if you want to use the high resolution textures. The main rendering
mode won't be able to take advantage of the dual TMU the same way
quake 2 does, so the extra TMU will be used for slightly higher
quality rendering modes instead of greater speed: trilinear / detail
texturing, or some full color effects where others get a mono channel.
Permedia 2
Will be completely fill rate bound, so it will basically run 2/3 the
speed that quake 2 does. Not very fast. It also doesn't have one of the
needed blending modes, so it won't look very good, either. P2 does
support 24 bit rendering, but it won't be fast enough to use it.
ATI Rage Pro
It looks like the rage pro has all the required blending modes, but the
jury is still out on the performance.
Intel I740
Should run good with all features, and because all of the textures come
out of AGP memory, there will be no texture thrashing at all, even with
the full resolution textures.
Rendition 2100/2200
The 2100 should run about the speed of a voodoo 1, and the 2200 should
be faster. They support all the necessary features, and an 8 mb 2200
should be able to use the high res textures without a problem. The
renditions are the only current boards that can do 24 bit rendering
with all the features. It will be a bit slow in 24 bit mode, but it
will look the best.
PVR PCX2
Probably won't run Quake 3. They don't have ANY of the necessary
blending modes, so it can't look correct. Video Logic might decide to
rev their minidriver to try to support it, but it is probably futile.
RIVA 128
Riva puts us in a bad position. They are very fast, but they don't
support an important feature. We can crutch it up by performing some
extra drawing passes, but there is a bit of a quality loss, and it will
impact their speed. They will probably be a bit faster than voodoo 1,
but not to the degree that they are in Quake 2.
Naturally, the best cards are yet to come (I won't comment on
unreleased cards). The graphics engine is being designed to be
scalable over the next few YEARS, so it might look like we are
shooting a bit high for the first release, but by the time it
actually ships, there will be a lot of people with brand new
accelerators that won't be properly exploited by any other
game.
