SLI support - Working solution
*edit (03/12/2013)*

BMT and (0i0i)5m4rt4l3X[-CH-] pointed out that the latest beta drivers, version 331.93, don't need the new fix anymore. The official profile is now using the correct SLI compatibility bits, so you'll only need my guide if you're using drivers older than 331.93.

*edit (27/11/2013)*

Updated the guide with a new fix that uses the official (but broken by default) profile.

*edit (21/10/2013 bis)*

It seems the official profile is broken and not working as expected. I've tried out the profile (as have "pnarciso" and "dynamite deluxe!", see their comments in this thread) and I get worse performance than the fix described in my guide.

With my fix, I get a silky smooth framerate that never drops below 60FPS (maxed out settings), while the official profile is barely able to keep the framerate above 40-45FPS.

YMMV though, and I still suggest you try out the official profile first before trying my fix.


*edit (21/10/2013)*

nVidia finally released an official SLI profile in the latest Geforce drivers (version 331.58). This profile is your best bet to get the best results on an SLI-enabled computer.

You can find more info and download links here: http://www.geforce.com/whats-new/articles/nvidia-geforce-331-58-whql-drivers-released

If you can't (or don't want to) install the latest drivers and would still like to get SLI working on an older set of drivers, be sure to read the guide below.


*edit (28/09/2013)*

Created a guide (link see above)


*original post*

I did some experimenting and found a simple fix to enable SLI. You'll need nVidiaInspector to make some changes to the existing Hard Reset profile, the previous game from Wild Hog. Both games use the same engine, so I decided to try adding Shadow Warrior executable to the Hard Reset profile with nVidiaInspector.

And it worked! Before this tweak, I had to run the game on High with SSAO disabled to get a solid 60FPS. This little change enabled me to run the game on Ultra settings with a rock solid 60FPS on my GTX580 SLI setup.


Quick guide:

1. Download nVidiaInspector here: http://www.guru3d.com/files_details/nvidia_inspector_download.html

2. After downloading, run nVidiaInspector, and click on the "Driver profile settings" button (little button with the wrench and screwdriver icon next to your current driver info)

3. Look up the Hard Reset profile

4. Click on the "Add application to current profile" button (6th button on the top with the little green plus sign on)

5. Locate the Shadow Warrior exe, and add it. You will need to choose "Application absolute path" option next to the filename box. This is needed because another profile already uses the "SW.exe" filename

6. Save by pressing "Apply changes"

7. Play the game with SLI enabled!


This should help out anyone that uses SLI until nVidia releases an official profile for the game.

That's impossible, you are missing a step or doing something wrong. Check the list carefully and be sure to APPLY the changes before closing Inspector. Another option at no. 5 is to delete the SW profile from the list and then add the sw.exe to the Hard Reset profile.

that's because you forgot step A. Buy a second Nvidia GPU and connect with current GPU using SLi bridge

Great work - works great. Now I'm playing around with inspector to try and inject some better AA.

Works great for me. Thanks for taking the time to share this info!

My solution offers better compatibility apparently, according to some comments on your guide.

Also, I'm not sure the SW profile that's already in the profile list is actually for Shadow Warrior. It's probably for a completely different game.

Theoretically you could try the same under the 3D Application Settings in Catalyst. I haven't given it a shot yet, but seeing as I'm suffering FPS drop with a 7970, I think I need to do something to sort it out. If Catalyst fails I'm going to reinstall RadeonPRO to get the framerate constant.

Since the SLI profile required some editing before it'd work, I'm betting you can't use the Hard Reset Crossfire-profile. I'll buy the game in a heartbeat if someone tries this and confirms it to work, but I'm not getting my hopes up and I don't want to fork out cash for something I can't even run properly or at all.

I wish RP had the same kind of crazy editing possibilities that Nvidia Inspector does. Maybe with some luck he'll implement something like that in RP Infinity. :>

Using the Hard Reset Crossfire profile did improve my FPS a bit, but it introduced some weird artifacting. This was with latest beta driver, and in the end I switched to an AFR profile and it works fine. The HUD textures get a little flickery though, and loading screens spaz out...definitely playable, if a touch annoying. But hey, much smoother gaming experience.

Didn't experience these things myself, but maybe that's because I'm not on the latest driver yet (i'm still using 320.49).

*edit* Scrap that, didn't notice you were talking about crossfire.

The only editing involved to get SLI working is simply adding the Shadow Warrior executable to the Hard Reset profile, nothing more. I have no idea if that can be done with Crossfire profiles though.
