I had motion blur on for 10 minutes then I turned it off. It was perfectly smooth on my system, but it made driving vehicles a pain.
Try out these settings and report back, please: // Everywhere Motion Blur - Goes in autoexec.cfg mat_motion_blur_strength .26 mat_motion_blur_rotation_intensity 1 mat_motion_blur_falling_min 10.0 mat_motion_blur_falling_max 20.0 mat_motion_blur_forward_enabled 0 // Infantry Motion Blur - Goes in infantry.cfg mat_motion_blur_falling_intensity 10 mat_motion_blur_forward_enabled 0 // Vehicles Motion Blur - Goes in vehicles.cfg mat_motion_blur_forward_enabled 1 mat_motion_blur_falling_intensity 1.0 // Commander Motion Blur - Goes in commander.cfg mat_motion_blur_falling_intensity 0.1 mat_motion_blur_forward_enabled 0
That's a prediction issue, happens with motion blur disabled aswell. And it happens at all speeds when in most vehicles, it's just not very noticeable unless you're moving fast.
