UE5 texture compression question

Hi, I am trying to reduce 8k targa textures within UE5 and I have noticed that the Compression setting has changed. I am trying to compress them and my question is
should I resize in PS save as png (no need for alpha for the materials)
or what is the best solution within UE5 to use lower res

Thanks so much in advance!


Found this thread wanted to share, still trying variation in UE5
