Holes on seams

I imported some models from an PSX game into Unity today and in order for the textures to show up properly I had to set the filter mode to “no filter”. This got rid of some black seams in my model but it only fixes it in scene view. Whenever I go ingame those seams turn into tiny holes. How can I set the filter mode permanently?

Fixed it myself. I just had to turn off Anti-Aliasing.
