One thing I’ve noticed people usually overlook is installing DirectX version that comes with games.
Now on more recent titles, youre more likely to have compatible directX libraries then not and never notice any issues, but with older games it is very important practice to go into game install dir, find one usually called Redist/Red or similar and find directX inside it and run setup as administrator.
Sometimes older games need those older binaries that don’t come with newer versions of DX9 and it can solve many problems.
Don’t worry about breaking anything else, as dx9 versions coexist in peace and harmony since as long as I can remember.
Any even if you have some other issues and not this one, this is still a good thing to do for older titles so just do it…
