@crinrict I did edit the new file to match the modded one, but there is a specific setting that needs to be changed that doesn't work with DirectX 11. It causes an error where you cannot get the interaction menus to popup such as sim interactions or making the sims move by clicking on a spot, and when I don't edit the setting and make the changes to all of the other settings, the game gets extremely laggy and stuttery under DirectX 11.
EDIT: No matter how well DirectX 11 will be tuned, I would also like to strongly recommend not forcing it and always leaving an option to go back to DirectX 9 for those who have graphic cards that don't support DirectX 11. That could be extremely problematic.
EDIT 2: In regards to the setting in the GraphicsRules.sgr (this setting is now in the Ts4CommonRules.sgr file) file, this setting needs to be at 1 to get a smooth experience with the quality improvements in the modded file:
setProp $ConfigGroup RenderPickFuzzinessRadius 1
In DirectX 11, this has to be at 0 which is by default, or else you can't click on a spot to move sims, and no interaction menus will popup when you click on a sim. In DirectX 9, this doesn't happen. Maybe the DEVs can take a look at why setting this to 1 is not working in DirectX 11 but works in DirectX 9.
When using the modded file with DirectX 11 with the edits and setProp $ConfigGroup RenderPickFuzzinessRadius set to 1, the performance is better than with the default GraphicsRules.sgr file, the panning is super smooth and the edge smoothing glitch I was having since the beginning of TS4 is gone. The FPS is lower still lower in DirectX 11 than it is in DirectX 9, but still the experience seems smoother. Also, the graphics quality is much better than the default very high settings. There is more distance, larger shadow textures, etc.
