So updating this because I just read on the Nvidia forums that an SLI profile was added to the game.

I can confirm that this is true. With this I can use the SLI profile with the same performance as Alternate Frame Rendering.

But this still does not fix the overall performance of the game. It really just maintains the same performance via a proper usage of SLI. The CPU usage is still all over the place and my fans are spinning like jet engines when I run this game.

I am guessing that the performance will improve when Nvidia releases an official driver with better support for the engine. And Larian still has work to do with optimization. As for the texture streaming that was patched today, I noticed very little difference and still get better performance with texture streaming off entirely.

The fact that Larian are going all in with this game, and the inclusion of full mod support, gives me high hope that these issues are only launch related.

Keep these threads alive though. And post your specs so we can gather info on which hardware is having the most problems.
