I am running SP, HM, no mods. I have an ASUS mobo 1 gig throughput with a Nvidia 1080, patched to the latest driver running 64 WIN10. I am not noticing any change in performance. In fact, once I did a complete lockup, and had to BOB it to restore functionality. I did hear the GPU spin up very hard prior to that lock. That is the first time I have had a hard lock like that.
Bug hunts are SO much fun Let me know if I can, or need to, deliver more details.
And now my buildings are transparent. I can visually see the walls, stairs, doors, etc. But my character does not react to them. I walk right through them. I can interact with my external devices (wheel, fire pit, etc). It happened on the first toon I had on Testlive when the new patch came out, so I deleted and started a new one. It has now happened twice. I don’t want to restart a third toon.
Good luck with this.
