This is just a tiny glitch but worth reporting anyway. I'm seeing lines around Marty that follow him around. The angles shift with the camera angle.
Running on an Acer 3820TG TimelineX laptop, which has an ATI Radeon 5650 chip, on 1280x1024 with every setting maxed out in the advanced settings screen. OS is Win7pro 64-bit. dxdiag attached.
