This is Salty 747 mod. I did a flight from KMIA to KORD to test the effect of long haul and FPS degradation. You will see as I start my approach my FPS will go as low as 23 FPS and my FPS will never recover from there. It will stay at 30fps max until I reload the airport and I got back to my original FPS which is close to 40fps.
Does your FPS stay at 40 FPS without the Salty 747 mod?
hmmm good question. I haven’t flown the 747 without the Salty mod for so long. I’ll give it a shot in the beta that starting tomorrow. unfortunately, I won’t be able to share my result with you.
I can tell you that I’ve used the WT CJ4 with the same issue as OP mentioned.
Sadly nothing much we can do about this.I use the same Salty mod and my fps dropped when I landed @KORD into the 20s.Lucky it wasn’t lower .Tried capping your fps?It’s the nature of this sim especially with mods.
