Honestly, I'm seeing no performance improvement from the patch.
This is extremely aggravating. If you're going to charge premium prices for a game ($50 for a new pc game), you need to deliver a premium product. This is completely bush-league, Larian should be ashamed of the technical failures of this product.
For those who have gotten this to work well, congratulations, but I don't really care to know about it. PM the Larian tech support dept. with that kind of garbage so they can try and isolate the game freeze/ stuttering problems.
