Whatever was done in April to the mouse detection or mouse movement really messed things up. FSX always had the FPS drop when using mouse look, but P3D seems to have fixed it. It was fine months ago when I first got Chaseplane. But now the dreaded 10-15 fps drop is back with P3D and recent builds of Chaseplane. This is really bad for me because I use a Gsync monitor. Gsync only works above 30fps. When using mouse look with Chaseplane, the fps drops below 30fps, making screen tearing absolutely horrendous.
