E la ho solo overcloccata di poco!
Tutto al massimo dettaglio e 320*200 di res.!

AHAHAH, 320*200?...io ti batto usando solo il processore;-)
Nono, comunque arrivo a 66fps a 512*384 (3dfx)...

Certo che si puņ!
Sarebbe interessante sapere come ! :-)

Ti interessa? Si parlava di questo da Bjorn in questi giorni.
Ecco qui sotto come. Ovviamente è in inglese, dato che non avevo
voglia di tradurlo!
	Come overcloccare il V1000
===================================================
V1000 
  
From Toni Lindroos: 
Hi,  
 I successfully overclocked my V1000L-P! Here's how:  
 ----------------  
 1) Use the latest miro v2.0 drivers.  
 2) Edit CARD0020.INI file (\windows\miro\timing\CARD0020.INI)  
 3) Find the resolution you want to modify (for example
[1152*864*1...@75Hz.VESA])  
 4) Add ´mclk=xxxxxx´ to this section. xxxxxx is the value which will
determine the clock frequency  
 5) You should start from 100000 and then go higher with small steps
(like 100000->105000 etc)  
     For example Windows 98 won't start with 140000 and is unstable at
135000.  
 6) When the system is unstable (distortion, computer crashing etc),
you should lower the value  
 7) If the Windows 9x won't start at all etc, just enter the dos mode
at boot (press F8 and then choose command prompt only) and edit  
 CARD0020.INI and lower the value.  
 Here's an example:  
 [1152*864*1...@75Hz.VESA]  
 mclk=130000  
 pll=108000  
 With this mclk setting my system (P188/64MB/V1000L-P) is stable.  
 Before: 1152x864x16 = 25 MP/s  
 After: 1152x864x16 = 38 MP/s  
 I take no responsebilities... Do everything at your own risk etc.  
 ----------------  
 I think these miro v2.00 drivers work with all BIOSes. I discovered
this quite accidentally. In the original CARD0020.INI there are no
mclk settings but the update program 
 which comes with the newest BIOS update adds mclk setting for some
display modes. I just compared the new and the old file and... Then I
just tried to modify those 
 settings. With the value 140000 I got 40 MP/s but D3DTest crashed the
computer.... I didn't try any RRedline games but I think this speeds
up at least 2D and D3D.  
 BTW, I haven't tried to modify the pll setting yet.  
 You may publish the information in your web site. Just say to the
users that they are doing everything at their own risk...  
 Ah, only 140 (of 285) mornigs left. ;)  
  
 Best Regards,
 
 
More on overclocking your V1000: 
 "Bjorn,  
     Your site has been really great for getting info on my card. 
Here's something that might help those who've been trying to OC their
V1000 cards. It works like a charm on my Screamin' 3D, so it should go
on a Canopus at the very least (filenames would be different).  
 Just as I was about to break down and buy a new video card, I learned
about overclocking the V1000 using MIRO drivers.  The drawback is that
the MIRO drivers are a bit immature.  You CAN use the Sierra drivers
instead! Just install the MIRO drivers, edit the line at the top of
card0020.ini in the windows\miro\timing\card0020.ini so that it 
 reads:  
 [MCFG]  
 default=137500  
 I use 137500, but most people seem to have trouble setting it that
high. Try 120000, and go from there.  Reboot.  
 Keep trying different values for MCFG and reboot each time you change
it. Now, once you've tested the card a fair bit, and you're
comfortable that it can run for hours at a time playing VQuake or
something similar, reload the Sierra drivers on top of the MIRO ones. 
Reboot.  
 Once everything is running again, reboot into safe mode, and enter
the windows\system directory.  Make a copy of wtscrm3d.dll for backup,
and then rename wtmirovr.dll as wtscrm3d.dll This .dll file controls
the timing for the card.  Reboot, and you're done!  
 Timedemo demo2 results:  
 Using just the latest Sierra drivers, Vquake @640x480 gives me 22.5
fps.  
 Using the modified setup, Vquake @640x480 gives me 26.8 fps!!!!  
 I'm using a p166 w/ 32MB SDRAM and no special commands for Quake. I
imagine that tweaking a few values in quake should give even higher
frame-rates, but I like all the details turned on anyway.  512x runs
at 36 fps if you like that resolution. Depending on the value of MCFG,
you should be able to see an incredible increase in speed.  
 Please note that I attached a 486 heatsink and fan to the Rendition
chip on my card.  Those who've tried to do this without cooling have
been much more limited in their success.  As with any overclocking,
there is a risk of damaging your card.  I can only tell you that I'm
not having any trouble with mine.  
 Make sure you have the latest Sierra BIOS, the latest Sierra drivers,
and that you use the latest MIRO drivers, too.  These are all
available (I think) at 
www.bjorn3d.com
 I didn't come up with all this
info, I'm just compiling it to make it easier for the computer
pseudo-illiterates like myself.  Obviously, I'm thrilled that someone
figured all this out.  Thanks to Martin and Toni who gave us this
info.

 ==================================================
Contento? I drivers miro li trovi a
ftp://ftp.miro.de/pub/driver/graphics/graphic/
Il file si chiama 800731.exe e sono 6 Mb.
Ciao, buon download e buon overclock!
P.S. Preparati a riavviare il computer decine di volte e, magari,
anche se non è necessario, a raffreddare il chip con una ventolina da
486.


effetti luce, acqua trasparente e anti-aliasing? Non credo.
Io vado (3dfx) a 58 fps a quella risoluzione con tutto attivato, acqua
trasparente, ecc. Comunque anche a me l'affermazione precedente e' sembrata
una inutile aria di superiorita'.

come si fa ad impostare l'acqua trasparente?

Ciao, buon download e buon overclock!
Grazie mille e Buone Feste !  :-)


come si fa ad impostare l'acqua trasparente?
Il modo piu' immediato (ma terribile come prestazioni) e' di scrivere:
r_vis 1
gl_wateralpha x
con x tra 0 e 1. Usalo solo pero' per vedere com'e', perche' le prestazioni
diminuiscono moltissimo.
Il modo giusto e' invece cercare 2 programmi: "bsp2prt" e "rvis". Ti serve
anche un programma per espandere i ".pak" di Quake, di cui non mi ricordo il
nome. Comunque sia prima usi questo ed estrai i dati, poi usi il bsp2prt per
ricalcolare i dati sui portali e infine usi rvis per cambiare alcuni bit
sulle texture e ricostruire i livelli. Alla fine hai l'acqua trasparente a
costo quasi 0.
