At Monaco with shadows turned off, i still get a long casting shadow at the bottom of the hill right before the chicane. this was a test with everything set to low of off to see the most i could squeeze out of the FPS. running a ATI 4850 1gb, dual core e6600 @2.40 GHz, 4gb ram, Vista 64, Samgung T260HD 1920x1200. I can get it rather nice with track detail and car detail set to high, and the rest low or off.. 60+ FPS lowered the effects to 16, and a few other PLR tweaks, and reconfig my ATI control panel. FOV set at 58.
