|   We have had our share of troubles with
      GeForce video cards.  In an effort to make their cards as fast as
      possible, NVidia skimped a little on the stability end of the
      equation.  The result was a very fast, high maintenance video card,
      which required significant effort to get all games and benchmarks to run
      properly.  The problems with NVidia GeForce and GeForce-2 cards were
      particularly noticeable in systems with the VIA KX-133 chipset.
         As just one example among many, the drivers that
      came with the Elsa Erazor X did not want to run 3D Mark 2000 in a PIII
      "Coppermine" processor running on a VIA KX-133 motherboard (Abit
      VT6X4).  The benchmark
      seemed to run in the background, but the screen went black, and the
      monitor light went to yellow (standby).  Playing with AGP wait
      states, AGP 2x vs. 4x mode, dropping the "acceleration slider" 1
      notch under the  performance applet, and reinstalling DX 7.0a had no
      effect on this unpleasant behavior.  Next we tried forcing 1x AGP
      mode with the following registry setting: 
      1) Open Regedit 
      2) Navigate to: HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\Global 
      3) If there is no 'System' key here, make one. Just right click on the Global key and choose New > Key. Type in the word System, and hit
      enter. 
      4) Now select the new System Key, and right click on it and choose New
      again 
      5) Now choose "DWORD Value" and type in ReqAGPRate. 
      6) Set the value for the new key to 1 You
      will need to reboot for this change to take effect.  Again, changing
      the AGP rate to 1x had no effect on the 3D Mark 2000 problem.
        
        Note that you can force 4X AGP mode with
      the following Registry Key.  I don't recommend 4X with NVidia cards,
      but you can give it a try by putting this DWORD value in this part of the
      Registry: 
       
      HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\Global\System 
       
      Now right-click on the System key, and select 'New'. Select 'DWORD Value',
      and type in: 
       
      EnableVIA4X 
       
      Set the value to 1, and reboot.
        
        Only one thing fixed the problems we were
      having with GeForce cards.  Updating the NVidia driver.  The
      first few versions we tried did not help (3.68 released, 5.13 beta). 
      The next driver set we tried was the Detonator version 5.22 drivers from
      NVidia.  This version actually fixed the blank screen problem in 3D
      Mark 2000, but it
      was plagued with another NVidia problem, the flickering or flashing
      texture problem.  Then about a month ago, NVidia leaked the 5.3
      version of their Detonator driver set, and that clearly fixed the major
      problems we were having.  We are now using the 5.3 driver on all
      NVidia cards from the TNT-2 to the GeForce-2, and they perform very
      well.  Frame rates are a little slower than with the 5.22 driver set,
      but it was worth it to get stability.  You can get the latest
      released and leaked NVidia drivers here:  http://www.reactorcritical.com/ We
      have not had time to check out the 5.32 drivers which have been released,
      but have heard good reports about them. Overclocking
      GeForce cards:   You can overclock
      all NVidia cards from within their newest drivers by doing a simple
      Registry edit to enable "Coolbits".  Simply open
      the Windows Registry Editor by typing "regedit" in the Run Menu
      of Windows. Then open the following directory: HKEY_LOCAL_MACHINE\Software\NVIDIA
      Corporation\Global Right click on the "Global"
      key
      and create a new key called NVTweak. Next, right-click on the
      NVTweak key and create a new DWORD value named "Coolbits."
      Adjust the value of Coolbits to "3" by double clicking on it and
      entering "3" in the value data field. Quit
      regedit and reboot the system.  Now a new tab called "hardware
      options" will appear in the GeForce 256 Additional Properties menu.
      (display properties > settings > advanced > GeForce 256 >
      additional properties > hardware options).  Go there to change the
      core and memory clock speeds.  The default values on a GeForce-1 card
      are 120 MHz core, and 166MHz memory.  We have had good luck with
      settings up to 130MHz and 180MHz.  
       Remember, the 3 things you need with GeForce cards and the VIA KX133
      chipset are: 
      1) The newest VIA AGP miniport driver (install the latest 4-in-1 VIA
      driver, which you can get here,
      currently, ver. 4.22) 
      2) The latest version of Direct X, which you can get here
      (currently, 7.0a) 
      3) The best possible NVidia video driver (currently, Detonator ver. 5.30,
      5.32 or 5.33), which you can get here.   I
      am very happy to report that virtually every problem we have had in the
      past with NVidia drivers seems to have been eliminated, or at least made
      un-noticeable, in the 5.3 and 5.32 driver sets. These drivers also allow
      you to enable the GeForce's full scene spatial anti-aliasing (FSAA). The
      controls for FSAA can also be accessed through the GeForce "hardware
      options" menu.  While this feature results in a dramatic
      performance hit, if your system is fast enough, you can enable partial
      FSAA and significantly improve image quality in some games.  But if
      FSAA is important to you, a Voodoo5 5500 card is a better choice. 
      It's method of generating FSAA is superior to the NVidia implementation.  For
