I'm using 2 GTX 970's in SLI. (see my sig for system specs) Running DCS 1.2 I took a performance hit running SLI. Only getting 30FPS. With one 970 in DCS 1.2 I was getting 70-80FPS constantly. I'm happy to report, in DCS 1.5.0 with SLI on I am getting over 110 FPS constantly. So yeah SLI works now. Beeroshima, your counter is not tricking you. The performance increase is amazing.
