NVIDIA GeForce RTX 2080 Ti NVLink SLI Scaling Explored

GeForce RTX 2080Ti NVLink SLI - Shadow Of War And Wildlands

Monolith’s surprisingly fun Orc-slaying title Middle Earth: Shadow of War, delivers a ton of visual fidelity even at its lower quality settings. So, to maximize the eye-candy on these high-end graphics cards, we used the game’s Ultra quality preset and ran the benchmark routine at a couple of resolutions, topping out at 4K -- or, excuse us, 3840x2160 for the sticklers out there. All of the game's graphics-related options were enabled, along with Temporal AA and Camera Blur. We should note this is the latest installment in the successful game series and our review of Shadow of War is right here, if you'd like to catch up on the happenings in Middle Earth.

Real-world gaming scenarios and game engines are what enthusiasts really care about. Fortunately, Shadow of War shows some clean scaling numbers. If you strictly focus on average FPS here, we see that with single card 1080 Ti to dual card you get an increase of 13.79% at 1440p. However, a GeForce RTX 2080Ti NVLink setup pulls a 31.36% gain.
Increase the resolution to 4K and we see more of the same with a 24% gain going form a single 1080 Ti, whereas on the GeForce RTX side, a pair of 2080 Ti's in NVLink will net you a gain of 50%. This equates to over double the scaling of legacy GTX SLI performance for GeForce RTX.

The render time is a reflection of exactly how long it takes to draw a frame, so it directly illustrate framerate scaling. However, we should underscore that lower numbers are better in these tests, as the less time it takes to punch out a frame, the more frames it can pump out in a second.

Tom Clancy's Ghost Recon Wildlands
DirectX 11 Gaming Performance
Tom Clancy's Ghost Recon Wildlands is a tactical shooter set in an open-world environment. The game is played from a third-person perspective, though there is an optional first person view when aiming certain guns. Players are members of the fictional "Ghosts", an elite special-operations unit of the United States Army. The game is also very taxing on system resources in general and perhaps not that well optimized, though it does look fantastic. We tested Wildlands -- which is a DX11 title -- with all of the in-game graphical options cranked up to their maximum values, at both 1440P and 4K.

Ghost Recon Wildlands Once again shows stronger scaling results, much to our surprise. This game engine has been shown to suffer at sub 4K resolutions, due to CPU bottlenecking. However, the GeForce RTX 2080Ti pair pulls out a scaling win here in NVLink, netting a 24.45% boost in average FPS over a single card. The GTX 1080Tis in HB SLI only pull a 2.14% gain overall.

Pump up the resolution to 4K, which is what Turing was designed for, and the gap narrows as the GeForce RTX cards in NVLink show a 25.75% scaling lift, whereas the 1080Tis come to life a bit, pulling a scaling gain of 16.80% in HB SLI.
