FPS seems consistently higher and more stable, far less sudden FPS drops to very low values, then back up high again, now;
Stuttering over land still present, particularly in fly-by external view, no noticable improvement there;
Appears to be slightly more noticable delay in texture loading, particularly at ground level in flicking between aircraft views;
Engine sounds slightly better - rpm variation more noticable, but did have some sound stuttering/dropouts from within cockpit of he111
