This update certainly has a massive impact on the GPU usage and performance. 

I could run 4xSSAA at around 50-60 fps (i7 9700K with a GTX1080) without any problem. Now I am getting 25 fps with the GPU sitting at 100% load all the time from within the cockpit. Outside view I am still getting 80 fps which is not that bad.

Very strange, this is even worse than the AS A330 on the same settings.

A new update has been posted that fixes the backlighting issue during the day (with the PBR model) and adds an optional performance-friendly glareshield lighting option (accessible through the Configurator). I've only been able to do a quick check, but it seems to reduce the performance drop by half on my 1070 Ti.

Cheers,

Tym

Thanks for the follow-up

While I’m glad to have seen and downloaded this new update; I think I’ve reached the conclusion where part of me wishes there was a non-DL option still, a way of reverting to the old lighting (minus maybe the new chrono backlighting).

One thing I noticed that VC rain effects start when rain starts but the VC rain effects remain enabled when it stops raining. Need to check in at the A2A forums.
