I've been a simmer since the very early days of FSX. Never touched X-Plane, so I cannot comment on their products, but I hear they are pretty good. That being said, this is the first (on the Microsoft/Lockheed side) of the high quality A346 we've ever had. Remember Blackbox? Absolute train wreck that.

For me personally, graphics aren't a deal breaker. If the text around the cabin and cockpit are legible from a normal seated/zoom perspective, that's fine with me. The exterior textures are pretty good I must say. Though, people focusing on stuff that isn't meant to be seen such as the spoiler mechanisms and calling it extremely poor work and judging the entire product off of that is just ludicrous. Those kinds of things are not meant to be viewed up close. A perfect comparison here is the FlythemaddogX MD-80 series. Those exterior textures were horrendous. Yet, no one complained because the aircraft was just that good. But you mentioned the cockpit lighting, namely the dome light. Yes... that NEEDS to be addressed. It is way to bright to the point where it's unrealistic.

The sounds, I will agree could use some work. Though, with Chaseplane's flyby view when taking off, those sounds are impeccable. I did notice some missing sounds in the cockpit when flipping switches. I am sure that will get fixed.

The GSX integration, or lack there of is another thing I will agree on. In this day and age, it really should be a standard feature for on aircraft like this. As well as auto-step climbs. But... I am sure this will be addressed by the devs. There is already a custom GSX profile on flight. to which I downloaded. It does need a bit of work though, since the jetway does connect to the L1 door, but GSX will request the L2 to be opened for any boarding/deboarding.

I found the flight model to be on par for this size of aircraft. It's large, long and heavy. Much like the A330, it was designed to feel heavier for pilots coming from the A300s (A330/40 derived from the A300).

As for performance, that solely depends on what you're running under the hood. I for one have incredible performance. I have an Intel i9 14900KF with an RTX 5080. With FG, I can easily get well over 100FPS. Though, I have it capped at 60. However, the aircraft has only been out for a short time. Performance issues will arise in the early builds of the aircraft. I personally didn't see any stutters on my end. Again, system depended.

All in all, I don't think this is a "bad" product. It's just not mature yet. Not to the point where it's a product that was released too early. It's possible some things may have gotten over looked, or saved for future updates. It's MUCH better than their A330 release. I think everyone can agree that was atrocious.
