Since SLI isn't working I'm only running essentially a GTX680 and on max settings it's not enough for 60fps, try turning off shadows and see what framerate you get as that crippled performance for me.
When I had my 680 I could play the game at a constant 60fps in 1080p while shooting hundreds of objects around the place with no lag. Must be the build.
There are, and I've maxed everything. I thought the vsync limits the refresh rate to my TV though, which would be 60 fps? I usually see tearing when it's off.
Well you should definitely be getting 60fps with a 780 as I get 40fps off the start with all the other cars around and dirt clouds, just wish SLI worked so I could play it properly at 60fps .
Well, this is annoying me now. I tried with vsync off and used adaptive in Nvidia settings. Played at 60 fps but there was still tearing. Enabled vsync in game and put sliders back to default but was only getting 30!! What am I missing here???
