[HL1/CS1.6] Disabling multitexture improves framerates dramatically.

[ZOVBOT]

Disabling the GL_ARB_multitexture extension in hw.dll leads to a dramatic improvement in framerates on my machine, without any loss in visual quality. I gained 200 fps standing in spawn on de_dustybleek, in 2festungen (Half-Life map) my fps would hover around 40-60 depending on where you are standing but with the extension disabled it runs right up to the framerate cap (1000fps) constantly.

As a consequence you will lose detailed texture support (r_detailtextures & r_detailtexturessupported), but very few maps make use of them and I had this disabled anyway, so no loss there.

It also seems to solve muzzflash stutter, and fps drops with flashlight, and nightvision without having to disable dynamic lighting.

Hardware: AMD 500 Series, Radeon RX 580 and AMD Ryzen 6 Core

As to the mod, search and replace in any hex editor, don't try this online.

Interesting, I've tested this in rocket_frenzy, a new map shipped with the 25th anniversary update and noticed a substantial fps increase.
