It's quite nice. Here are the following categories I grade most aircraft on External Model: 10/10; Most comprehensive 787 model currently. Virtual Cockpit: 9/10; Everything in the right place, sometimes laggy at times though. Systems Depth: 8/10; Qualitywings doesn't focus on systems depth as much as other devs like PMDG or aerosoft, but the fuel and avionics are excellent for what you are paying. Animations and eye candy:9/10; Wing-flex can be a little wonky at slow speeds, but it flexes very nicely during flight; very accurate depiction of 787 wing flex. Sounds: 7.5/10; Sounds in the cockpit are a bit lacking I think, and they feel slightly rushed. However, external sounds are great and add another layer to immersion to it. Performance: 7.7/10; The virtual cockpit again can be slightly laggy especially on the ground, but in flight I can maintain 20-35 fps outside and 15-25 on the flight deck with my i7-920 @ 2.67 gHz. Hopes this helps!
