In my opinion it is the best traffic add-on for 2024 at this time. I have tried the better known freeware addons. They are fine, but this one is very simple, download, run the installer, then run the Traffic Control Center. The models look very good and don't affect FPS.
One caveat is that if you're at very busy airports, you need to use the Traffic Control Center to dial down the spawn times (default is 90 minutes before schedule). If I did not do this, I would get an overload of planes at the airport and the sounds were constantly coming in and out. I think it was too much for my system Turning this down to 45 made everything smoother, and I still saw lots of airlines! I highly recommend this if you're like me and want it as simple as it can be.
The mod is amazing, gives you barely any fps loss compared to AIG Traffic and FSLTL. However what makes this not 5 stars is because it doesn't cover the entire world properly and the liveries are the majority of them not accurate. (mainly the ones outside of the western world)
I'd give it 5 stars if they fixed the liveries and the entire world coverage like AIG.
