Model textures looks low res (help)

[Can]

3D model textures looks low res in game, texture size is 1024x1024. Anyone knows a solution ? (My CSGO settings on high)

Thanks

Maybe the original resolution of the texture is small? Or the brush has the texture scaled up. Could be few things to be honest. I would start with brush texture scale since the other textures looks ok.
