Thank you for the discussion guys! I've had a chance to try out the P-51D Mustang just now, but am experiencing the same stuttering again... I decided to put it on video to show it to you guys. I will post the same issue on the ED forums and see what I get...

Experiencing stuttering (sharp FPS drop every second or so) in DCS 1.5.6. The video is of the P-51D Mustang module, but stutter also exists for the other 2 free modules (Su-25 and TF-51D). This is the Instant Action/Take Off Batumi, though there is stuttering in other missions as well.
Have tried low, medium, and high graphics settings. Have tried turning in-game V-Sync on and off, as well as NVIDIA control panel V-Sync options (On, Off, Adaptive, Adaptive (Half), Fast). All with same results.
