Nvidia SLI GUIDE

This guide will allow SLI to properly work with Cities: SkylineDotA 2 (A user just messaged me and said this guide of mine is working for him in DotA 2 after trying many methods prior).

1. Download Nvidia Inspector, it's a power user tool for customizing Nvidia gpu profiles and settings. http://www.guru3d.com/files-details/nvidia-inspector-download.html
2. Open Nvidia Inspector and open the Nvidia profile configuration http://i.imgur.com/6AGnrFL.png.
3. Create a profile for Cities: Skyline http://i.imgur.com/Lbg64q4.png. (You can name your profile whatever you want, it can be SDFJK or cat this doesn't matter it's just your name for your custom profile)
4. Add application to profile, Cities.exe from Cities: Skyline http://i.imgur.com/IJuVqgJ.png Go to DotA 2 profile on the list instead, it will be there already.
5. On the setting SLI compatibility bits (DX1x) change the profile to 0x000121F5 (BioShock Infinite) then hit apply changes on the top right.

After you have finished this, the next time you start Cities: SkylineDotA 2, your SLI will work perfectly, nearly 90% gpu usage on both GPUs on average in my experience. The gameplay is much smoother with SLI on than default non SLI for me.

When you install new graphics drivers it usually wipes the custom profiles. If you plan to install new drivers, you should save this profile first using Export user profiles, then import them after you install new drivers. Or you can start again from step 2 of this guide.

Alternative Method

Open the Nvidia control panel, select, "manage 3D settings", highlight the program settings. Click the, "Add", tab. The Cities: SkylineDotA 2 Icon should be around the top of the list. Scroll down until you locate the, "SLI rendering mode". Select the, "Force alternate frame rendering 2". That should enable SLI support for Cities: SkylineDotA 2. :D

SLI for DirectX 9

I've figured out how to enable sli for d3d9. You have to use sli compatibility bits 0x42C06405.
Here's what i've got (everything maxed out, 2560x1440 G-Sync GTX Titan Sli):

Thank you so much, mate! DID IT ON MY LENOVO y510P with GT 755 SLI! IT WORKED WELL! WITH DX9, with dx 11 there were artifacts on the screen!
