The latest update to FSLTL is extremely heavy on FPS in MSFS2024. I’m losing 15–20% with the default settings. It wasn’t like this in previous versions. Is it just me experiencing this?

I'm not noticing that at all. I only use FSTL and AIG together with Beyond ATC and I limit the amount of AI to a just below a medium setting. If you have too much AI flitting and parking about it will sink your FPS no matter which package it is. Also, I have the default AI completely off.

I have my FPS locked to 32FPS, amplified via Frame Gen to 128. As such, I do not notice any performance impact of any AI traffic solution...

The update made no difference to performance in my sim. However, you can adjust settings when you start FSLSL by clicking Y instead of N if you want to adjust the number of aircraft the application will render to improve performance. Personally, I'm fairly happy with the defaults.

Keep in mind that the FSLTL liveries are almost all saved in 4k and I think but am not certain that the models only have 2 LOD. Both of those reasons will chew into performance. It's easy, but at a cost.

[SOLVED] I reinstalled Windows and MSFS 2024, and now it runs smoothly at a constant FPS.
