Nico,

While overall performance of PSXT/RT has improved recently, I'm still seeing issues during initial phase (25-35 seconds). During this phase all active (live) planes get frozen and remains so for a long time. This is especially true in large airports, when you have 15-20 live planes at specific moment (KORD, KLAX or KDFW).

Is there any way to eliminate or reduce this issue OR I'm doing something wrong.

PS: I use RT Direct

I tried KLAX but it is difficult to reproduce. I test (without static aircraft) with Little Nav Map but everything is moving.
Could you give me a UTC time and date when you see this?

Will do. It's all not consistent with time or an airport.

Thank you.

KATL, June 9th, 19:58 Zulu. A lot of frozen AI are heading to 26L for t/o, while actual take offs are from 8R.
