Low performance on RTX 5080

[FizzyElf]

So I got the game recently and played it both on a system with a 3060 and a 5080 and I am seeing really poor frame rates regardless of my graphics settings or resolution (Which I suppose is sort of nice because if there is no difference in FPS then might as well max out the settings.)

The 3060 system has a Ryzen 7 5800 and 16gb of ram on an SSD with about middle of the road speeds for gen 4 drives. The other system has an I9 275HX, 16gb of ram and a lower speed gen 5 drive (samsung evo plus, runs cooler but only hits high gen 4 speeds.)

The FPS in the model viewer/encyclopedia hits around 47-58 FPS on both systems while actual battles can be anywhere from a constant average of 13 FPS to a constant average of 47 FPS, again settings and resolution don't matter, nor does the power settings or changes via the nvidia control panel and in both task manager and MSI afterburner the game is showing that it is using a good chunk of my system, sitting around 10-13gb of VRAM, 70-100% GPU usage and it often hits 50% CPU usage while nearly maxing out the system memory at around 11gb's used while the system uses the rest. And bear in mind that I am hitting nearly 60 FPS in game in cyberpunk 2077 with ray tracing on ultra before doing any frame gen nonsense as well as hitting 150+ FPS in warhammer 3 all within the same hour as Sea Power so it's not like the new system is suffering in other games and it didn't appear there were any issues with my previous system and other games (though obviously a 3060 definitely needs more toned down settings).

I really like the game and I like taking screen shots but I actually want to start playing it as an RTS and I can't really do that if it's running this poorly, any advice?
