I'm just using MaxProcessorCount to fix the odd jagging from my character which happens when I just run & mouse turn, and I didin't honestly even look if it even improves the frames, but I'd imagine it to at least make the game feel more fluid as thats what the reason I'm using it anyways.
Then I did test the settings one by one, but its been awhile.. so I'm just roughly going to say that:
LightTileCsPathEnable 1 - Minor 5 fps bump.
TransparencyShadowMapsEnable 1 - Major frame boost on top of that.
Anyways, It's really strange because TransparencyShadowMaps should just decrease frames or do nothing at all, and I did compare screenshots just to make sure that I'm not breaking something. So I'd guess that there is some conflict with it which causes it to loop and draw some frames.
Thank you for the detailed post, Nurmi! I have tested the two commands, but didn't notice any performance increase or decrease on my end. Maybe these commands only help those with AMD GPUs, such as yourself? 
I'm having trouble with SweetFX. This is about how far I've gotten:
Game directory looks like this, the SweetFX_settings txt file is the preset I'm trying to use, which is also selected through the SweetFX Configurator.
What could possibly be going wrong? Thanks in advance!
If you are using Windows 8/Windows 8.1, then that might be the reason, but even then I would not use SweetFX Configurator. I would recommend the following:
1) Delete every single SweetFX file from your DA:I folder and remove/uninstall SweetFX Configurator from your system altogether
2) Download the SweetFX version linked in the OP: http://www.file-uplo...in-8.1.rar.html
3) Extract the SweetFX files in a separate location and only copy the following into your DA:I folder: SweetFX folder, d3d9.dll, dxgi.dll, eFX.ini, SweetFX_preset.txt and SweetFX_settings.txt
4) Go to the SweetFX settings database and download your favourite profile into your DA:I folder: http://sfx.thelazy.net/games/game/777/
5) Open the downloaded preset file and see if the effects inside (SMAA, FXAA, CA, EXPLOSION, CARTOON, LEVELS, etc.) match the ones in the SweetFX_settings.txt file that you copied over from the archive
6a) If all of the effects match, just delete the SweetFX_settings.txt file, rename the downloaded preset file as "SweetFX_settings" and you're good to go!
6b) If the effects do not match, then you will need to manually edit the copied SweetFX_settings.txt file to mirror all of the values in your favourite preset
This should let you use SweetFX with DA:I without any problems, but should you encounter any, or if you have any questions, just report back and I will be more than happy to help you out! Good luck! 
I'm not using SweetFX Configurator so not sure what trouble you have, but, anyway, I had problems getting SweetFX to work with DA:I until I used the SweetFX for BF4 x64 you'll find linked in this thread. Works fine with that version for me.
Yup, that version worked perfectly fine for me as well, which is why I've posted the link in the OP quite some time ago. The only problem is that SMAA injection just doesn't work with Windows 8.1 at the moment, but the SweetFX guys are working on it. A beta version of SweetFX 2.0 with the much improved ReShade injector is already available, if you want to give it a go: http://reshade.me/
