Hi. Unwinder, could you add more tweaks to OpenGL like nVdia Tray Tool has got ? I mean Force Multitexturing and Texture precache. I think these are some registry tweaks, so it could be easily added to RivaTuner. And if it woudn't a problem it would be nice to have Coolbits in RivaTuner so it will be one tool for GFX tweaking . Nvidia Tray Tools eats a lot of memory like for that small app( about 20 MB :3eyes: ) and have the same uncomfortable interface as try tool bundled with drivers :3eyes:. //edit: I found out that the Force Multitexturing in Nv Tray Tools is the same as the option Enable GL_SGIS_MULTITEXTURE in 16-bit modes in RivaTuner. But in Riva tuner is grayed out. What this do exactly and should I use this with 80 release of Forcewae drivers. I also notice that you disabled this option for forceware 5x and higher. May I ask why ?
