The four games on this page were all tested using built-in benchmarks. We collected three samples at each setting, throwing out the first one, as minimums were often quite different in first runs versus subsequent runs, perhaps due to caching of game assets.
This game doesn't pose much of a challenge to the GTX 980 Ti, even at 4K. In fact, what you'll see here is that we're throwing so much GPU power at the game that it's becoming CPU bottlenecked. We're seeing only 35% SLI scaling at 1440p, and a slightly more reasonable 60% at 4K. But trust us, despite using a relatively game engine that's easy on video cards, it sure looks good!
This game has traditionally been a nearly perfect test of GPU power due to its very low CPU requirement. Indeed, SLI scaling is quite good, 75% at 1440p and 79% at 4K. More importantly for gamers with a single GTX 980 Ti or similar card is that this card is very playable at 4K even at "Ultimate" settings. While it hits only 45fps, this game engine doesn't require ultra-high framerates to feel smooth.
Another observation we'll make here is that 4K performance tends to be about 50% of what we hit at 1440p, and indeed, this is something we'll see over and over again in our testing. It provides a simply way to approximate how a system will respond at 4K if you know its performance at 1440p.
Metro: Last Light
This game is an absolute beast when it comes to the demands it places on video cards, and it isn't much easier on CPUs. In fact, at 1440p, we see only 62% SLI scaling, although the game is relatively playable at this setting. Clearly, our heavily-overclocked six-core CPU isn't strong enough to allow the dual GTX 980 Ti cards to run at their best. Look at 4K, however, and we see amazing 89% SLI scaling. The bad news is that a single card simply isn't enough to handle this game at 4K - this is the worst showing for our single GTX 980 Ti in any of the eight games we tested, despite it also being one of the oldest games in our test suite. At least it's putting all that power to good use - the game looks fantastic!
This game responded very oddly to running at 4K. While it was clearly pushing our cards very hard, with performance well below what we experienced at 1440p, SLI scaling was terrible (under 45%). What's worse, the game looked all wrong at 4K. The game simply wasn't rendering correctly - it actually looked like it was pushing out pixels at 1080p, despite hittiing abysmal framerates. Given that no other game we tested responded this way to our testing, we can only conclude that the game isn't fully compatible with a 4K resolution.
This game might be dropped from our testing suite soon, but the four games on the next page will not, as they are both very popular and very good tests of video card power.
