It jumps between 55-90 fps very frequently (Specifically when turning in-game) which is what makes it feel stuttery I believe.
I'm running the game on a 4070ti super so the FPS being that low and inconsistent isn't ideal (Even more so on a simple LIDAR game), it becomes especially obvious on a 180Hz monitor.
If you were running it on a mid range laptop where you're expecting ~60fps on a lower refresh rate monitor it would be a lot harder to feel or identify that.
That said, the game is definitely playable for those who don't mind the FPS drops, it just won't feel smooth.
Ok thanks for letting me know about this problem.
The thing is that all particles are calculated by the CPU not the GPU (so in this specific case your 4070ti is "useless") and I can understand now what you meant with the inconsistency.
To use GPU for the particles is a little more complicated and I need to do a litte of research to implement it in the game.
