My test for smoothness is taking off from KLAX 25R (default but NOT Asobo enhanced) then turning towards KBUR - if I get stutters there, then I’ll probably run into trouble elsewhere.

I have things set so that I can take off very smoothly with the Asobo PC-24 or the Inibuilds A310 or A330, but the default Asobo 737 Max creates several stutters on takeoff and once airborne.

I suspect my 10900K CPU just isn’t strong enough for a stutter free experience as the CPU is probably also getting hammered by rendering Los Angeles autogen.

I remember in 2020 the MD-82 by Leonardo was terrible on my rig and the BAe-146 could be as well…maybe they just use more CPU?

In your experience, what are the heaviest and lightest complex aircraft CPU-wise?

Heaviest:
Fenix A320 series

Most iniBuilds airliners

FBW A380, but this might be more dependent on your GPU 

Lightest:
PMDG 737

It's probably a VRAM issue. Turn on developer tools, then Tools > Display Framerate ... monitor the VRAM usage, if it goes yellow you're cutting it fine and stuttering is likely.
