bad viewport visualization

Hi all, I’m pretty new with Unreal and I need some advice:
why my viewport is so jagged? but, most important, why in play mode the quality drops even down!?!, there is some setting that I must “play” with?
I’ve got a GTX 970 4Gb video card,…don’t think it’s not enough.
Thanks a lot for anyone could be helpful

Hi, check if your engine scalability settings are set to epic. You should find them under world settings or project settings in the top bar.

thanks a lot Robbie, it worked, now looks great!
