OK full reinstall fixed it so now i can play the game but i have another problem. It lags, and i am not talking about framerate issues, the game runs smoothly for 30 in-game days then it takes full 2 seconds to pass one in-game day (at fastest speed). Changing the resolution to lowest doesn't work. How to fix this?
Its not a graphic issue since graphics in Paradox games dont use much resources. Instead its a problem of calculating power since those games rely on RAM very much and are not using it very effectively (bad optimization). Try fixing by changing how much RAM is available for the game. From what I recall once a month is when some calculations are being done in the game so it makes sense...
