Hello I have decided to switch to Windows 95 emulation to PCem because I found out that this is a better emulation solution than DOSbox SVN,

But thing that has been questioning to me.
Does Voodoo2 work on PCem? If it does that would be a great solution for playing any late 90s windows 3Dfx games. Like when I was playing Lego island with the 3Dfx voodoo 1 cards in Windows 95 on PCem v10 the FMV slows down, but I found a video on the web that someone had a voodoo 2 ( And it occured to me that maybe this will up the FMV framerate.) working on their win95os on PCem, I wonder how?

If not Voodoo 1 is the only solution... Maybe someday in future versions of the emulator that we will get some Opengl feature on PCem, (I doubt that is ever gonna happen.)

No. Voodoo2 is a different, upgraded chip with many new capabilities, and Voodoo2 emulation won't fix your Lego island problem.

a new fast CPU that can handle Pentium dynarec with infinite cache will

besides, Pcem's v1 speed is actually a bit on the Obisidanish fast side, and frankly it's fine for a lot of the 1996-2000 releases anyway.

Also note in that video he's playing on a ViRGE with excruciatingly slow framerates, which indicates the "Voodoo2" he installed is not working at all. A Voodoo2 would play those two racing games smoothly

Well when are we gonna get Opengl on PCem? Also how good is the X branch of PCem with 3Dfx?

Having 3dfx being output to an OpenGL viewport won't solve your Lego Island FMV problem.

Stick to the vanilla upstream repository if you want the fastest (and working) 3dfx support.

What would be the right ROM, BIN and PCem settings to get the fastest and working 3Dfx support?

A Core i5/i7 from the past 5 years and Pentium MMX 200MHz with Infinite cache.

It doesn't. There is no virtualization.

To get the fastest PCem build you must compile the tree yourself with profile generated optimization. I don't think i'll bother explaining that though, so just add -flto for now
