Yes, I'm using an older version of opengl - utglr34. I use this cause it works best for me. I don't use "embellishments" cause it interferes with the game. All reflections, flashes, glows, additional moving things like waves, flames, detached limbs, bodies, blood and even burns after hitting some obstacles like walls, floors and others, I have turned off. If you often have a headache after playing, throw it all away.
