Hell, I've suffered years due to the fact that I had *no* shaders at all. Until last year's Christmas. I will not, never ever so to say, tone down or disable any pixel or vertex shader settings that are available. I rather set them high and go down in resolution or texture quality or watch a slide show XD
But I think what kills FPS are the physics and in game effects maybe also post processing, in fact my FPS get a real boost when I switch those to low.
Anyone got a good .ini file guide?
