Yes that is also double buffered vsync
If you want triple buffered vsync enable borderless fullscreen
Wouldn't the triple buffering option in Nvidia Control Panel work too?
Also, this is easily one of the shittiest-performing games I've played in quite a while. Constant stutter whenever a unit moves, occasional drops below 20fps when a unit emerges from cover to fire, atrocious hardware utilization (GPU usage never goes above 90% in missions, CPU usage sees random spikes to 90-100% during benign scenarios, which never occurs in any other game). Gotta wonder how much worse it would've been if they didn't delay it.
