SBGL 2020 native custom ground poly crashing game?

[Gimala 4]

Hi all,

Just had an issue with SBGL 2020. Coming in the PMDG 77W, started crashing on approach. Removed the custom ground poly as in the guide:

And it stopped crashing. However, lost a lot of FPS.

Any ideas why this is happening? Is there a fix I can do to stop the crashing? Would like to do a few more flights there but the FPS is terrible with the custom ground poly disabled.

Cheers!

Are you running out of VRAM, perhaps??

Nope, was happily sitting at less than 3 GB - was wondering if that was the cause.
