Same issue.
Ryzen 5700X3D
32GB Ram
GTX 980 (Which should be more than enough for this game)
FPS (Lowest Settings: 45-60)
DirectX11: Works Better (DX12 should handle calls better though?)
Vulkan: Randomly drops and keeps being at 20fps (Which means this game becomes unplayable for Linux, however I use Windows for DirectX currently)
Note: Vulkan always has performance issues regardless of settings.
The game or engine still needs better optimization, I use vsync-off which helps, and thankfully because of a very high hz monitor it doesnt show tearing, but on lowest the game looks bad, on max settings it looks better than bad but still bad and has much worse performance (around 40fps average rather than 90 in the training sandbox which is less demading!)
Overall the game does not look so good to be justified for the performance even if the graphics card is a bit older as of 2024, the card is still good, it plays games like black desert online (in their remastered) pretty well and at constant 60, the game should at least run 144 at lowest (but 100% render... obviously), features such as nvidia reflex utilize high fps in higher machines, so having only modern (rtx specifically) hardware run the game marginably better does create an accessibility wall for many.
Server CPU: 70 peak (Match 5752216)
In comparison, both Dota 2 and CS2 play butter-smooth and they look good, understandably so this game doesnt perform that well because it is in alpha so the earlier those problems are tackled and figured out the better for everyone, and it should of course be resolved in time, its normal to not notice whilst in a more close alpha.
In comparison Smite 2 in UE5 performed horribly bad at the first alpha weekend, the second was a bit better but still bad, the third and forth were a bit better and then acceptable respectively.
The game is really fun for what it is and has potential, so those small issues shouldnt be allowed to cause any more trouble.
I also suggest distance-based renders, because it is obvious assets are rendered, when looking away from the edge of the map it increases fps while when looking towards the opposing base from ours it decreases fps massively, meaning there is a lot of render density of things overwhelming the GPU unecessarily, albeit I understand some of the reason behind that and that is because we have fast travel times and ziplines, but still, some solutions should be found for even older yet top tier hardware. RX580 for example, or GTX780 and above, there is not low-enough settings for those and the higher ones do not look that much better to justify performance costs.
