Most Recent SLI Supported Games With Decent Scaling

Scalable Link Interface (SLI)

So what is SLI? And what does SLI do, or more specifically: how does it help me run multiple graphics cards to improve my gaming? Scalable Link Interface (SLI) is a little gem given to use by the masterminds over at Nvidia in 1998.

This technology was first used by the company 3dfx on their Voodoo2 graphics card line in 1998, but later the company was bought by Nvidia and the technology was shelved for a while.

In 2004, Nvidia re-released SLI with updates to allow it to work with the then-current technology of PCIe buses.

Although there are compatibility concerns (discussed below), associated with running multiple GPU setups, SLI will allow the use of two to four cards at once. It achieves this by using a parallel processing algorithm, which takes the information, breaks it down into smaller pieces, and allows for multiple pieces to be worked on at once by multiple cards.


Looking for useful list of games that work with SLI

SLI works fine with PS2, in the past it didnt, currently it does. While SLI is nice, you should probably just save up and get a GTX 1060 or 1070 as either one beats a 970, a 1070 may possibly beat SLI 970s(Unsure). But if you do go with SLI 970s its recommended to have atleast 16GB of RAM to match the 4GB/4GB VRAM.

What Modern Games That Support SLI Do You Recommend?

While some games don’t offer significant performance gains for SLI’d setups—especially at 1080P resolutions—there are still quite a few games out there that can benefit from using multiple NVIDIA graphics cards at higher resolutions. We’ve listed five modern games that support SLI and that have been shown to offer decent performance gains at higher resolutions when running on an SLI’d system.

If you have an SLI-based system that has helped give you a performance increase in other modern games not listed above, let us know in the comment section below so we can add that game to this list!

Types of SLI Configuration

There are three types of SLI configurations in which you can connect multiple GPUs (up to 4).

2-Way SLI – In this, you can connect two single GPU graphics cards in SLI mode using 2-way SLI Bridge.

3-Way SLI – In this, you can three single GPU graphics cards in SLI using 3-way SLI Bridge.

4-Way SLI or Quad SLI – This is also called Quad SLI and in this, you can connect 4 single GPUGraphics Cards in SLI using 4-way SLI Bridge or can connect two dual GPU graphics cards using 2-way SLI bridge. You cannot connect 3 or 4 dual GPU graphics cards in SLI because that would make it Hexa and Octa SLI configuration which does not exist.

Note: 2-way SLI is the most popular and active SLI configuration used today because Nvidia has reportedly dropped most of the support for 3-way and 4-way SLI. This is because of the complexity involved in driver development. Modern graphics cards such as GTX 1070, GTX 1080 and higher will only support 2-way SLI.

Is SLI Still Relevant?

Since 2004, the SLI technology has come on leaps a

Since 2004, the SLI technology has come on leaps and bounds to keep up with the ever more demanding needs of modern games, particularly of the AAA variety.

SLI tech still features in the majority of Nvidia’s line of GPUs, including the most recent RTX series, which boasts SLI transfer bandwidth upwards of fifty times that of previous technologies thanks to the new SLI NV-Link Bridge.

Where SLIs relevancy starts to waver is when it comes to game developers. Optimizing a game for SLI support is a painstaking process and requires the release of purpose-designed updates on the part of the developer and specific driver tweaks on the part of Nvidia.

More often than not, an AAA title will deliver poor SLI performance at launch, that is, until the patches and drivers mentioned above can be updated, and a stable SLI profile is developed.  At this point, the technology unquestionably comes into its element and drastically improves games.

The first month is when SLI users suffer, but given time, the experience becomes well worth it. For games that are a year or two old and support SLI, the performance is better across the board (20%-40% range, generally), other than a few exceptions and variations in how much improvement the tech contributes.

For Nvidia, SLI, as a proprietary tech, is worth propping up and supporting for years to come; it means more GPUs are sold, increasing their annual profits. 

With the advent of extremely powerful single GPUs — read GTX and the RTX line —, that are more than capable of handling the demands of “ultra” settings on the most power-hungry games, the need for multiple GPUs is less and less apparent.

Developers are, therefore, increasingly less likely to invest time and resources into SLI support when the majority of players migrate or stick to the single GPU setup.

The rendering techniques required of an engine to support SLI are complicated at best. In many cases, bugs and fixes that affect a majority of gamers rank higher in a developers’ to-do list than SLI optimization. For these reasons, fervor for SLI support on the developer’s end is not as pronounced as it used to be.

SLI is also the GPU technology of the tinkerer by excellence. In most cases, SLI profiles supplied by Nvidia and developers do relatively well. Still, more often than not, the in-game graphics options are there to be tinkered with before obtaining optimal performance.

Arguably, the golden age of SLI support was around the time when the Nvidia 900 series was all the rage around 2015-2016. The relative affordability of these GPUs made SLI a far more accessible technology back then.

In many ways, the GPU market is at a turning point where SLI could quietly be confined to the annals of history, or remain a niche yet in-demand technology.

For example, SLI is a good tech for those with the finances to build a state-of-the-art dual RTX setup or those who are avid partakers in older games, say World of Warcraft, and can get their hands on two GTX 980s or GTX 970s.

Middle Earth: Shadow of War

The second installment of the Middle Earth series

The second installment of the Middle Earth series wasn’t quite as well-received as the original Shadow of Mordor. However, Shadow of War still received fairly positive reviews overall. Its graphics, however, help the game stand out, which, of course, means that the game will need a fairly decent system to run. Its minimum GPU requirements call for a Radeon HD 7870 or GTX 660 and its recommended GPU requirements ask for an RX 480 or GTX 970.

The game can be run on a 1080P monitor with a budget-friendly GPU on lower-to-medium settings with no problems. However, at higher resolutions, more GPU power is necessary to get the game running at a decent framerate. And, fortunately, the game does support SLI—although, on launch date (and soon after) users found that their SLI-based system was actually delivering lower framerates. Guru3D’s benchmarks did show that SLI’d GTX 1070 Tis did deliver a lower framerate on a 1080P monitor. However, the SLI’d 1070 Tis were able to deliver a modest performance increase on Shadow of War at 1440P and they delivered an even bigger performance increase on a 4K monitor.

Destiny 2

Initial Release Date: 6 September 2017

SLI Support Added: Included On Launch

First released back in 2017, Destiny 2 is more than alive and kicking in 2019 with many expansions since and a thriving community. The game also supported SLI from the start for the performance elite, and results has widely been reported as rock solid. For a couple examples, see it running super smooth and with nice high frames in 4K with GTX 1080 SLI here and RTX 2080 Ti SLI here, but you’ll find many benchmarks and tests online that show good scaling and smooth performance with SLI enabled.

So, We Can’t Have Multiple GPU Setups?

We can but, considering more recent technological

We can but, considering more recent technological advances, there’s no need to do so. Having been outperformed by NVLink, SLI was quickly considered an obsolete technology. NVLink functions far more efficiently and aims to correct the mistakes made by SLI and, for the most part, it succeeds.

NVLink significantly improved upon SLI’s master-slave concept by instead using mesh networking, which allowed every GPU in the setup to function properly on its own as an equal contributor to the overall processing.

It also introduced NVLink Bridge, which substantially outperformed the SLI bridge. This all means that NVLink is currently a far superior option if you’re looking to link up two GPUs.

Again, it’s important to emphasize that modern GPUs such as the RTX 3080 or more budget-friendly options like the RTX 2060 or RTX 2070 will still be an excellent option for almost any modern game.

In fact, purchasing a second GPU will likely be a waste of both time and money.

Strange Brigade

Initial Release Date: 28 August 2018

SLI Support Added: Included On Launch

Another recent AAA game that can scale really wellAnother recent AAA game that can scale really well with SLI

Strange Brigade is a great game, and one that has built-in mGPU support (DirectX 12). This benchmark saw a whopping 93% scaling with NVLink 2080 TI SLI in 4K, which is some of the best SLI scaling around. Or if you want to get ridiculous, see it running around 60FPS in 8K thanks to a monster SLI Titan RTX setup. Smooth 8K gaming in triple A titles is only feasible with SLI, as a single Titan RTX or 2080 Ti is going to be in struggle town for most modern games.

SLI Bridge Series

BridgePixel Clock SpeedMax BandwidthRecommended Monitor Support
Standard Bridge400 Mhz1GB/s1920×1080 through 2560×1440 @60 Hz
High-Bandwidth Bridge650 Mhz2GB/sUp to 5k and surround sound

If you have more powerful cards (like say the GTX 1080), you can use a standard bridge, but it won’t allow for the full performance of the cards. The high-bandwidth brides would allow for this.

Final Thoughts On SLI

It’s time to admit that SLI just isn’t it. To be honest, we should have admitted that five years ago, but very few did. In 2018, NVLink gave us a consumer-ready replacement to go along with the new RTX series GPUs and that was the death blow for SLI.

You might have noticed that most of the games where SLI actually provides an increase in performance were released around 2015, SLI’s long gone prime years.
