SLI Fix Found for Rise of the Tomb Raider

Rise of the Tomb Raider is off to a flying start on the PC. The games graphics are jaw dropping, although, given the graphical powerhouse that we saw from the last game, that’s hardly surprising. Pushing the game to its limits is proving quite easy thanks to a well optimised game engine, and Nvidia has already released a GPU performance tweaking guide, ensuring you’re getting the best graphics and frame rates you can on Lara’s latest adventures.

The only major issue so far, as is often the case with modern gaming releases, is that SLI isn’t exactly working as we had hoped. If anything, SLI performance is a complete and utter mess on Rise of the Tomb Raider, at least for most users. Thankfully, ‘Blaire‘ from 3D Center has found a few simple tweaks that can not only get the SLI back up and running as it should, but they’ve even reported 95% scaling between their two Nvidia GPUs; I would test it right now, but I’m running a pair of AMD cards, so that may be a bit of an issue although reports are already showing similar results.

To get it working, you need to create a custom profile. You do this using the Nvidia Inspector Tool, where you can search for the Rise of the Tomb Raider profile and change its SLI bits (DX11) to 0x080002F5. Once that’s done, press on the magnifier icon and this will reveal Nvidia’s Undefined Options. Search for 0x00A0694B and set it to 0x00000001.

See, that wasn’t hard was it? If done correctly, which I’m sure you did, you should now have proper SLI support and see proper performance scaling.  Now get back to your day/night of gaming and enjoy the full performance of your shiny gaming hardware.

Be sure to let us know in the comments if you got it working, or not!
