PoP Problems

My current PoP has slow performance, and obvious visual artifacts.

When I downloaded it, I selected full download. Is that all I needed to do? Or were the patches required as "full" reads 3.611.

Additionally, is it compatible with Warband 1.160?

As of May 24, PoP 3.611 is compatible w M&B:W 1.158.

Not sure if it's also compatible w 1.160, but posting your question in the "Quick Questions, Quick Answers" thread would be the quickest way to find out.

As far as I know pop is compatible with version 1.160 as thats  the version I'm using now and have had no anomalies with a fairly good amount of gameplay.  As far as I know the only thing that was added in the 1.160 was steam worskhop related tweaks and from the changelog that was posted for patch 1.160 all mods that work with 1.158 should function normally.
