For full details, bare LOD and visibility limits set to 200 km 3.4 GHz CPU is not enough with complex aircraft like A320family. For less complex planes that config should be enough. For 200 km visibility over very detailed Europe regions You will need 32 GB RAM, in generally 16 GB is enough.
Check my videos :
1. Less complex planes (707 and Concorde) at Kai Tak
for comparison with P3Dv5.2 You can check this video
https://www.youtube.com/watch?v=EASqVUAPL-w recorded on machine with almost same as my config. And here
https://www.youtube.com/watch?v=4UAbt6paVmA is same approach and landing, on another customer's machine on P3Dv5.1 and resource extreme heavy FS Labs A320. I do not have that very nice FlyTampa scenery
2. Concorde full flight from London to New York :
3. Maximum settings, A320 family at Innsbruck - A320 is resource very hungry, result is jittering and stuttering even on powerfull machines
4. again A320 and Innsbruck, but without real world buildings (OSM data), performance is bit better, but still jitters and stutters
My machine :
AMD Ryzen 7 3700X at 4.2 GHz all cores
GTX1060 6 GB
32 GB RAM
