747/787 poor performance?

[M3Stang 27]

Wondering if its just time to upgrade, or if anyone else notices poor performance specifically with the 747/787s. The A320N and other prop planes seem overall usable. Its just the Boeings that kind of have a hard time for me. Did a flight from KLAX - KSFO and on final was getting like 3 fps couldnt even land and the game became unresponsive. First time ever in 275 hours of play time.

I don't find they have a bad performance and i fly this Birds a lot..

But i assume this still have to do with the performance of the sim itself.

I sometimes get complete holds of the sim from seconds but the Boeings are just performing OK for me.

cheers 😉

I noticed with the Heavy Mod 787 that the performance was abysmal compared to the FBW NEO. I remember in the past that the NEO had a terrible performance because the displays were highly CPU dependantant. I don't believe FBW fixed that, but they did in their remaking of their displays make it less performance impactful. 

I think the 787 is still suffering from that initial pain of the default ND. My recommendation is for you to see if the Glass Cockpit Refresh Rate will give you a boost by going to a LOW instead of Medium or High. 

Hope that helps.

I've found the 747 cockpit performance to be pretty good (probably better than the FBW on balance) but the 787 performance is just awful, unfortunately. It often seems to get worse toward the end of a longer flight, too. External view performance is fantastic, making for a very obvious contrast.

I agree it's almost certainly something to do with how the cockpit displays are coded. Even low refresh doesn't make it much better, but medium or high refresh absolutely trashes the framerate.

I have the 6700K and it's OK for FSX - but depending on your settings, it may not be optimal for 2020(?)

Afaik it's a Javascript Garbage Collection (GC) problem. An object, if not in use anymore, has to be erased from memory. Coherent GT/JS does that very regularly and that can result in microstutters. So the programmers need to find ways to avoid GC producing microstutter. Maybe by keeping and reusing objects. Well, developer stuff I don't entirely understand. 🙂

Tried a long haul yesterday with the 787 and it CTDed after 5hrs over the Atlantic. Never had any CTD with only flying the FBW neo or CRJ…

Yeah it is getting long in the tooth but just about every other aircraft is fine on my system at ultra 200 LOD 1440p so I kind of blame the aircraft 😜

I use both the 747 and 787 all the time with no trouble.
