Specifications


Make sure you have the latest patch for Half-Life. The 1.1.07 patch and later supposedly fix problems
with missing textures.

Make sure you have the very latest drivers installed. The 5.13+ drivers fix the missing textures problem,
the 5.16+ drivers fix problems with flashing in shadowy areas and the 5.22+ drivers fix problems with
slow loading times.

Make sure you run Half-Life at a resolution below the current desktop resolution.

Try changing the Buffer Flipping Mode in the OpenGL tab of the NVIDIA control panel to 'Block
Transfer'.

If you get blurry text in Direct3D mode, try moving the Texture Alignment slider in Advanced Direct3D
options in the NVIDIA control panel to the 0 position.

If you're using OpenGL (recommended), try using Direct3D, and vice versa.

Try flashing your GeForce card's Video BIOS with the latest version (you may have to use the NVIDIA
reference BIOS). This may fix problems with green pixels being displyed instead of grey. You may want
to read the 'Where can I get the latest NVIDIA Flash BIOS and which should I use?' question in this
FAQ.

Q. Half-Life is too dark. How can I fix it?

If the brightness and gamma controls in the NVIDIA control panel don't work, try adding the command


If you use OpenGL, create a folder in your game directory called 'hw' (so that it looks like 'c:\sierra\half-
life\cstrike\hw' or similar), and then create a file inside that called 'opengl.cfg' with the following
contents:
GAMMA 5
TEXGAMMA 2
LIGHTGAMMA 2
These values can be altered to change the brightness levels.

fix it?
This problem only occurs when you enable the console using the -console command line switch.
You can fix it by changing the Buffer Flipping Mode in the OpenGL tab of the NVIDIA control panel to 'Block
Transfer'.

Q. I have Counter-Strike and a GeForce 2 Ultra 64MB DDR and my framerate drops
dramatically whenever there is more than one person (myself) connected to a server. What's
up?
This is a very unusual problem but one that has been experienced by a number of people. Getting a different
model GeForce card (the GeForce 3, or the GeForce 2 MX) appears to fix the problem, but apart from that
