When i press Play to render, My textures have now became blurry

So,this was sudden. My game has been running smoothly until for the past few days, it had a ‘texture stream’ error came up and my textures are all blurry. I had tried to do it by command r.Streaming.PoolSize= 2000… in the preview things improved (but still not as sharp) and when i click play, its still pixelated/blurry. Help!!
