Recently, I've been having this framerate problem on the ground.
When I'm taxiing or rolling, the framerates are sickening, and even ATC stutters. However, once my wheels are off the ground it's silky smooth. I only have this problem when I'm on the ground. The frames seem to stutter and go back and fourth. But again, everything is fine in the air. I updated my drivers, and even re-installed the program. Same thing. Any advice?
