Sounds like your laptop is trying to run the game with your Intel video instead of your Nvidia. That's about the performance level I've seen from integrated graphics.
Check inside your zero-k folder for a file called infolog.txt. Fairly early in the file you should see something like this:
[GR::LogVersionInfo]
SDL version : 2.0.8 (linked) / 2.0.8 (compiled)
GL version : 4.6.0 NVIDIA 466.27
GL vendor : NVIDIA Corporation
I'd bet that yours will probably say it's using the Intel instead. If so, then you would need to use your Nvidia driver software to tell Zero-K (spring.exe) to open with the Nvidia card, and the performance should pick right up.
