I've purchased the A300 (which is quite an expensive aquisition, not saying it is unfair, just highlighting that it is a big effort to spend money on such things), mainly because of the cargo version. And got completely disappointed by this stuttering issue, and I have got a high end setup (I think so...):
Processor: Intel(R) Core(TM) i9-14900KF, 3200 Mhz, 24 Core(s), 32 Logical Processor(s)
Installed Physical Memory (RAM): 96.0 GB
Graphics Card: NVIDIA GeForce RTX 4080 (16GB dedicated memory)
The issue happens mainly during the camera transitions/ moves.
I have recorded a video but unfortunately it is not so obvious as it is while playing:
I understand that you are busy, but please at least let us know that you are trying to fix it somehow.
Thank you and best regards.
