Playing on win 11 and it lags really bad. any known fixes?

Where you can issue commands while the game is paused (like in Age of Empires/Mythology, Emperor the Battle for Dune, or Homeworld)? Thanks for your answers p.s: for reference, here is a full list of RTS featuring tactical pause https://gtm.steamproxy.vip/groups/pausetacticality/discussions/0/2906376154321402758...

As soon as the game starts I have a glowing cross and then the game crashes. Major graphics glitches. How can I fix it?

I played all the tutorials, yet on the first mission for the Malus, I had to restart several times to even get five minutes in! How am I supposed to maximize my damage to enemy fighters? Do I just suck?

i cant see anything when i launch the game, there just appears to be a neon circular cross and just pulls around the screen with the main menu video. the rest of the screen is black.
