how to make texture higher res?

[chilly carbon]

hello i want to make my texture higher res so people can read it. but i dont know how to fully do that since im very new and this is a custom texture

do i just have to raise the resolution in vtf edit? and if so does that raise anything in the map? like do higher res textures make the map weight more or have worse performance

technically you can set the texture resolution to 1024x1024 and have it be readable just fine

since the texture is gonna be higher res it will ofcourse weigh more, i don’t know about performance much but it will prob be fine
