I'm running v2.5.1 of nHancer with my nVidia GTS 250 video card with V182.50 drivers, and I'm having problems with blurring textures, shimmering and AA problems. I've cranked the settings up in nHancer, but they don't seem to be working well. I notice particular problems on Lemans, Curibita and other tracks. Anyone with similar hardware and drivers and nHancer who are happy with the results? Would you mind posting your settings or suggestions? Thanks in advance.
