Ok first question...how do i add back that 3dfx logo when a glide game starts (only NATIVE GLIDE GAMES support it aka NFS2 SE or anyother game that uses glide?...i tryed the Voodoo2 Tweaker but nothin')
Second question: what's the best overclock value for the card with no additional cooling and in a closed box ?
Third and final: any new drivers for the card or tweakers in the near future ?

Cya

you are using what version of Voodoo2 Driver?
no 3DFX Logo when play NFS:High Stakes and GTA2 while playing Streets of Simcities, i can see the 3DFX Logo

The last set of drivers I used on a Voodoo2 were released from Diamond MM and there was an option to show the 3Dfx logo or not on start up of a Glide game.

I wouldn't OC your Voodoo2 more than 10% without adding cooling because it runs fairly hot to begin with. TennMax makes a great cooler for the Voodoo2 (Stealth V2 Cooler) that will allow you to jump the card 25%.

I'm using FastVoodoo 4.6 and what Mhz to set it 95 is good or more like 97?...with NO ADDITIONAL COOLING
Ok i get it about the 3dfx logo...

No need to type "no additional cooling" in all-caps. I wasn't telling you to buy cooling for your V2. I was answering you question by saying I wouldn't go over 10%. I also added an option if you decided that wasn't enough for you.

Really, no need to YELL, I was just trying to help you which I WILL NEVER DO AGAIN!

I've found something about some Tweek program -no tweeker-, and Voodoo Wizard program to make those kind of things you wanna do, like disabling 3Dfx logo before a Glide game starts.
You can also define this variables in autoexec.bat -for example-:

set SST_RGAMMA= 1.7

set SST_BGAMMA= 1.7

set SST_GGAMMA=1.7

set SST_GAMMA=1.7

SST_GRXCLK=57 (BE CAREFULL A RANGE FROM 50-57 SHOULD BE SAVE, OVER 57 IS DANGEROUS!)

set SST_VIDEO_FILTER_THRESHOLD=65535

set FX_GLIDE_SWAPINTERVAL=0

set SST_TEXMAP_DISABLE=1

set FX_GLIDE_NO_SPLASH=1 (En/Disable rotating 3Dfx Logo

set SST_BACKPORCH=1

set SST_FASTMEM=1

set SST_FASTPCIRD=1

set FX_GLIDE_SHAMELESS_PLUG=1
