Guys, I have been reading up on this topic so much and I have tinkered for countless hours but I just cant get rid of this jagged edge on the track lines and guard rails. I am running Nvidia 560 GPU and I have my FXAA turned to 36, I have tried setting the LOD bias to Clamp, and allow (the screenshot is with CLAMP set) I have turned Anisotropic filtering off, and then every interval to full. It does look alot better with AF set to off, and Negative LOD bias set to Clamp, but there is just this spot between where its right in front of me, and when its far enough for the mipmap to blur it, where it still looks like a set of stairs and its keeping me awake at night while I try to cry myself to sleep. Has anyone found out any kind of trick or work around to get it nice and smooth? Thanks guys!
