Hello!
I am running A-10C on a laptop (i7-2720QM/GTX 485M/8GB Ram/Intel 320 SSD+500GB HDD) at 1920x1080, all settings maxed out (except water @ low and MSAAx4). In the instant action missions and flying online, i get 60fps with TGP ON in normal flight, but this can drop to ~35-40 when things get really busy. It's been amazing so far and with the sim installed on the SSD, i have only had one or two short stutters so far. Hope that helps!
