With the advent of the 25th Anniversary update this guide is no longer required for the current build of the game. Disabling texture filtering is now integrated in the video settings. This guide is only useful for older builds that can still be downloaded in the library options.

OpenGL is cool, but I hate the texture filtering. Here's how to get rid of it.

Removing texture filtering from your current play session

Simply open up the in-game console and enter GL_texturemode GL_Nearest

Remove it everytime you start a game

1. Go to your Half-Life/valve directory - (typically its in Steam\steamapps\common\Half-Life\valve)
2. Find to your autoexec.cfg file
2a. If you don't have one, simply create a txt file and rename it autoexec.cfg.
3. Open it with a text editor
4. Add the line GL_texturemode GL_Nearest
5. Save and close

Congrats you did it! Now you are playing Half-Life like its meant to be played.

"I'm not a fan of the SNES graphics" has to be one of the more hilariously head-in-ass statements I've ever heard in relation to this game and I've heard plenty.

as somebody who owns both a 1998 crt, and a 2005 crt which i daily drive, yes there is a slight 'blur' as a result of the rounded phosphors, no, in no capacity do they vaseline the image as hard as the opengl texture filtering does. if your crt is doing that, chances are your electron gun is out of focus, which is an issue of calibration and you need to fix that by turning the focusing potentiometer on the board inside.

the natural blur is very subtle, if anything all it really does is mask aliasing, it doesn't hide very much detail, and the negatives can be completely negated with a little bit of sharpening, which i always add. i would know as i use these things for modern games, desktop work, video/photo/texture editing, and know how to maintain them.

you cant replicate phosphors by fucking up the textures with crappy filtering.
