Posted: March 7, 2000 Written by: Dan "Tweak Monkey" Kennedy More Display Settings Tweaks - OpenGL Settings Now, head over to the OpenGL settings. Remember that these will work for most first person shooters like Quake 2, Quake 3, or Half-Life and that these will also work if you're using your GeForce 256 for 3D modeling programs like 3D Studio Max or Lightwave.  Enable buffer region extension - This doesn't apply to most games, but it does apply to 3D modeling programs. If the program uses the GL_KTX_buffer_region GL extention, enabling this will speed it up. So, if you use 3D modeling programs, enable this feature. Otherwise, leave it alone. Allow the dual planes extension to use local video memory - If you enable the option above, enable this too to gain even more performance in 3D modeling programs. Leave it disabled if you didn't enable the option above. Use fast linear-mipmap-linear filtering - This option will speed up OpenGL performance at a slight cost of image quality. For the most part, the games will look almost the same. Distant filtered objects may appear less detailed. Enable it if you're looking for performance, or leave it alone if all you want is image quality. Enable anisotropic filtering - Enable this for a nice increase in visual quality. If a game supports anisotropic filtering, this feature will add a fine and accurate filter to textures, such as the distant floors in a first person shooter. However, if you enable this you may lose performance. Enable alternate depth buffering technique - As with Direct3D, this will enable a slower but more detailed buffering technique for 16-bit. In our tests, we did not see any noticeable increases in visual quality, so you should probably leave this alone as well. Disable support for enhanced CPU instructions sets - For most users, this option should be left unchecked. If you experience problems, try checking this box and see if it fixes your problems. Default color depth for textures - Most new games can override this setting, but some older games (like Quake 2) cannot. Set this to your preferred color depth for games. Note that 16-bit is about 10%-30% faster on most games. Buffer flipping mode - Leave this on Auto-select. The auto-select method is nearly 100% accurate, so you shouldn't experience any problems if this setting is left alone. Vertical sync (VSYNC) - This is the same as with Direct3D, except it's for OpenGL instead. We recommend that you leave it to "Always off". As with the other setting, change it if you experience tearing. Use up to x MB of system memory for textures in PCI mode - Set this to 0, since the GeForce 256 is AGP only at this time. Your GeForce should be running in pure AGP GC-MMP AGP Pipelining Mode rather than GC-MMF AGP Frame Mode. If the performance is poor with PCI Texture Memory Size set to 0, consider upgrading your drivers or set this value higher. Experiment until you find a sweet spot. Thanks Heat for the info. Hardware Options Open up the Hardware Options tab. What's this!? Yep, Nvidia finally included an overclocking utility with its drivers. To adjust the clock speed, you'll need to reboot your computer once you've selected "Allow clock frequency adjustments" the first time. Once you've rebooted, you can now adjust the clock speed and even test it out. Before you go and start playing with this option, read on for more on overclocking and cooling! Hit "OK" until all the windows have closed down. Now... on to overclocking! If the Hardware Options tab is not there, follow the coolbits registry tweak on page 4! |
