  • G400 using only half of its memory?

    Hey folks. This isn't that big of a problem, more of a concern that one of my friends at Microsoft informed me of. We're both using DirectX 7 BTW. It seems that our G400 cards are only using 16 out of it's 32 MB of memory. While I don't know if this is true or not (I'm not a big hardware guru), I ran dxdiag and got the following:

    The first group of settings is for my PC, the second is for the TV output. Notice how both of them say the card only has 16.0 MB of memory when both our cards (mine and my friend's) are the 32MB vanilla versions.

    Any ideas on why this is? Maybe DX7 is just dumb? =)

      Mines the same as Marmita, dxdiag sas that i have approx 32 mb of display memory also. Eithr something has gone wrong with the installation(unlikely) or you've been stiched, sorry.

      Take it up with the store that you brought it from if your not sure.

      have a look in the display properties/information in quickdesk, it'll tell you there what amount of memory you have on the card.

        I don't have a G400 so I don't know, but would splitting the video to dual monitors result in it appearing to be two 16MB cards?

            Make sure DH is off, than check again, cause when Multi Monitor mode is on (not sure about dvd and zoom)G400 divides it's memory on 2 halfs

              Don't worry, you didn't get ripped off. Speedy is right. I've actually tested this out. When DH is enabled, DXDiag will report 16MB. I'm not sure what effect this has in terms of gameplay though...

              Anyone know if Q2/Q3 takes a performance hit due to memory when DH is enabled???

                  It works fine with 5.30 drivers. Gamespy in one screen, Q2/3 in the other...AWSOME!!!

                    Are you saying the DH multi-monitor is now working with Q2/Q3? Is that in OGL mode or D3D?

                      It has to be OpenGL, cuz Quake2/3 do NOT support D3D... (Quake2 did work through a d3d wrapper though)
