Tim mentioned in a previous posting that one of the devs would be looking at this shortly. Has any progress been made? With Build 660 graphics options on and set to maximum, HDR without multiview gives a steady 70 FPS on most of the tracks tested (Belgium, Brianza, Nurburgring, Lime Rock & Silverstone). Multiview with no HDR gives the same 70 FPS. Multiview + HDR gives 15 FPS on all tracks. Also, the headlights on the cars have a very faint illumination at night using the 'gp_realistic_clear setting' at Belgium. It is almost as dark as driving without lights. Lights are ok if HDR is turned off. Do any other multi-gpu users experience this? Thanks
