Issue: (updated on June, 9th)
When spawning or approaching detailed airports like EDDF, the fps got locked around the 20fps mark and the VRAM warning appears ingame with random CTDs / driver timeouts.
The fps won’t recover throughout the whole game session.
Slewing away from big airports doesn’t result in normal fps behaviour.
Starting a new flight doesn’t bring normal fps back either.
The game has to be restarted completely to fix it.

Switching Photogrammetry OFF fixes it
A restart of the game isn’t needed.
What i’ve tried:
- aircraft type doesn’t matter.
- live traffic OFF and AI planes OFF.
(i’m playing usually at ultra with TAA @100, no FG, LOD to 200 / 400 with around 70 to 100fps) - setting the object and terrain LOD to the lowest value doesn’t change anything.
- changing graphics settings all to low, increases the fps to 30
- deleted rolling cache
- deleted shader cache on amd adrenaline
- switched Photogrammetry on/off → culprit
Effect:
- game is unplayable when wanting start/land on big airports
Notes:
I demand to fix this (kind of) issue with a hotfix and not waiting until the next sim update.
(OT)
It would be also interesting to know if the same issue happens on consoles.
I’m personally not a fan of console support of such a game type, which downgrades the experience for PC users.
Consoles where made for playing Super Mario /s.
Update:
- minidump context from last CTD: ‘amdkmdag.sys’
Update 2:
- also happens on small airports like LSZR
Update 3 (June, 9th):
- Photogrammetry ON seems to be the problem
