Leatrix GFX??
 

Did this addon just dissapear? I cannot find it or a replacement. I am trying to get wow running on a very old machine and this addon would work great for the tiny tiny VGA it has.

Can anyone direct me to where this went, or even a replacement?

The 4.0 game client is missing several of the graphics API CVars used by the pre-4.0 version of Leatrix Gfx. While I'm not sure why the post-4.0 version (v4.06?) is no longer available on this site, I do know that it only contained a handful of graphics CVars not already covered by the 4.0 in-game video settings UI (those are ffxGlow, ffxDeath, gxcolorbits, gxdepthbits).

Entering them manaually in your config.wtf acheives the same objective:

SET ffxGlow "0"
SET ffxDeath "0"
SET gxcolorbits "16"
SET gxdepthbits "16"

(I personally never saw a performance increase using 16 bit depth/color on my low end systems both pre & post 4.0, but there is definitely a noticeable FPS increase from disabling ffxGlow.)

Hope that helps!
