Bristol Airport - microfreeze over Rwy 27 threshold EVERY time!

Every time I fly over the threshold (or thereabouts) at EGGD, it hangs for about half a second, really badly. It doesn’t happen anywhere else and I’ve tried a huge variety of (low) GFX settings, to no avail.

Intel i9 - 12900k 3.2ghz

64gb RAM

Rex Real Global Airport Textures

I delete the rolling cache before every flight, exit the menu, go back in, switch it back on.

I’m wondering if it’s something to do with the millions of cars in the car park. Has anybody got any ideas?

Not a huge deal, guess I just won’t fly into EGGD - but really annoying not being able to figure out what’s causing it…

Thanks!
