As promised here are some screenshots of the new update!
(Keep in mind the update is NOT released yet, release is still planned for end of August)
Performance!
Here is the frame rate change on the mansion level after reworked lighting and the new AI system:


Although fps will vary by system we can see that the cpu time has been reduced by 10 times as well as the render thread! This is similar across all other levels, meaning you should be able to run the game with the new update on nearly any computer!

Graphical Improvements:









The screenshots are from home invasion, the mansion, and the collector. In comparison to current Sneak Thief graphics you will noticed improved lighting (more reflections, less weird artifacts, improved lighting interaction with non-static objects), Improved textures (8k resolution photoscans, you will be able to reduce this in graphical settings if you are playing on an older system), and more detailed meshes.
Keep in mind the update is not finished new textures and new meshes are still being added among other improvements. So, what you see in these screenshots is subject to change however it will give you a good idea as to what sneak thief will look like upon the release of this update!

Thanks to the community for all the support while I work on this! I hope to get it out as soon as possible, and as always if you have any questions feel free to ask!
