Just going to drop this here since it's relevant...
I'm happy that i've read that you're going to be working on performance at some point in the future and it answers my concern of this post but I do want to address some comments I heavily disagree with.
Voxel games are in some ways more demanding, yes, however:
1) There are plenty of games that are voxel based that perform way better than this: Empyrion galactic survival, Minecraft with mods, Teardown, Space Engineers, ect.
2) This game was initially released in 2013. We've had almost 10 years of hardware advancements and yet the game runs worse than previous alphas (this is somewhat to be expected as more features and graphical capabilities are introduced but we should be seeing improvements overall, not regressions). I can use a Intel 7th gen quad core CPU or a 12 core Ryzen 5 5900x and see very little change. I can use a GTX 1080 or a 3080 and see again, very little difference.
If your GPU rasterization is faster than the physics / update cycle of the engine, you end up seeing that your CPU is throttling your system because it can't keep up with the frequency GPU draw calls.
If your GPU rasterization is slower than the physics / update cycle of the engine, you end up seeing that your GPU is throttling your system because the draw calls can't complete fast enough to keep up.
What we're actually seeing is under utilisation of both the GPU and CPU which indicates bad hardware scaling.
Honestly i don't undesrtand people. In past 30 fps was standard and now 45 fps is not enough for them. Honestly i don't see any diffrence bettween 60 and 30 fps xd
30 FPS was standard in 5th gen consoles, 15 years ago. 60fps is the standard and has been on PC for well over a decade. Consoles have only just recently adopted 60fps but nonetheless, its the standard everywhere. That's why phones have 90-120hz screens, thats why theres a huge market for high refresh rate monitors and that's why YouTube spends millions every month, serving the entire world videos in 1080p 60fps or higher. Have you tried to play a VR game in less than 60fps? Yeah you can't. Why? Because it induces motion sickness.

If you can't tell the difference then good for you, however, the rest of the population can.
I'll be looking forward to playing this game again once its not a slide show in cities.
@Matt115 It´s not the FPS drops that bother me. It´s the stuttering lag, the mini freezes happening in downtown. There is low FPS and there is lag. Two different things. Lag shouldn´t happen at all.
Lag is terminology that usually describes network latency.
Stuttering / freezing when rasterizing is most commonly caused by poor IO (input/output) performance, main causes are not enough RAM so the system has to write to the page file (disk), or slow disk speeds when streaming resources into RAM, or not enough memory on the GPU so it has to keep dumping data and loading new data in frequently in order to rasterize.
It's usually not related to the performance of the game unless they're doing some very odd logic.
