Well.. I overclocked my N900 to 900MHz and now Sygic is running very smoothly with these settings: fps=20.0 antialias=false PositionFiltering=false Before overclocking the maximum FPS value was 16.0 and if I tried to increase it I faced some lagging and jerking when map moved. Now there's no lagging or jerking with 20.0 fps and it looks really smooth while driving
