Getting DX 11 to Work Well with Triples

[zero7159]

In case you had not heard, iRacing has finally added DX 11. I upgraded to it on Tuesday night and after plenty of tweaking, so far so good for me. Now I am generally getting a steady 60 FPS on my triples, with vsync on, using DX 11. I have triple 27 inch monitors with a resolution of 5760 X 1080. I am running a Core i5 2500k CPU overclocked to 4.2 ghz, plus a 4 GB EVGA 970 SSC GPU. Very smooth, even when the FPS drop below 60. I have run with lots of cars in front and back of me at Phoenix, Daytona 2011, Montreal and Charlotte. Here are my Nvidia driver and iRacing Graphics settings:

I cant even get iracing among with any other dx9 game to run due to the nvidia/microsoft update issue to run anymore.
I did get a chance tho to test it the day of release before my drivers went to shit, if i recall with the base game setting iracing set i took a fairly large fps hit down from 160+ to 80-100fps in practice mode and didnt really notice a much of a visual difference
Looking at your Nvidia control panel i could be mistaken but without changing Antialising-mode to override any apllication setting your antialising - transparency setting of x4 supersampling is not being activated

Good catch. As I was tweaking the DX 11 settings, I found that when I tried to force antialiasing via the driver, performance was worse than when I used AA in the game. The prior settings I used with iRacing DX9 had AA controlled through the driver.
