Is there such a card that was built with GX (Not GX2), and used more than 2MB of SGRAM memory?
Why? Some DOS games that support only S3D, lean towards only supporting the Virge 325. A low frame rate chip. I've read that S3DTool is a utility that can patch some of those games to support DX/GX/VX.

But maybe not GX2 or MX.
S3 VIRGE Terminal velocity in dos.
This "could" give S3D only games, that also do not support non 325 chips, a faster chip to work with. So if that's the case, I want to know which is better. DX or GX? The only advantage I can find between DX and GX, is that GX supports SGRAM memory over EDO. I am also assuming SGRAM is better than EDO.
So if what I stated above is legit... Then would this cause a desire to find a GX card that has more than 2MB of SGRAM memory built on?
During such an ebay and google search, this is what I have found and it appears to be conflicting.
There is conflicting information about the memory types used with DX and GX chips. Wiki tells us that the DX is an upgrade to the original Virge 325. And the GX is also the same upgrade, but supports the newer SGRAM instead of just the EDO that DX supports. If that is true, I would conclude that:
- Cards using Virge DX can only use EDO memory.
- Cards using Virge GX can use EDO or SGRAM memory.
Here are some images I keep running into that conflict my perhaps very poor conclusions.
Here is a Compaq card with a GX using SGRAM. It's the only one I can find, but unfortunately is only has 2MB on board. Likely the reasoning of this being some kind of "office" computer card. But the theory holds up. It's a GX with only SGRAM.
Next, is another card that uses a GX chip, and has more than 2MB of memory. But it only is utilizing older EDO memory. So the hunt is still on, but at least the facts (if I'm correct) still line up.
Here we have a Diamond Stealth 2000 using a DX chip and EDO memory. I don't want a DX nor EDO memory, but at least the theory still holds.
And then my theory went out the window. What is this?? 😕 It's a DX using SGRAM. Is it not?
Does this mean DX actually can support SGRAM memory? Does that then mean the GX and the DX have no difference?
I'm failing to find the existence of a GX card that utilized more than 2MB of SGRAM memory. I am also failing to find the difference between DX and GX.
Can anyone help me understand better or care to speculate?
Thank you
