Assassin’s Creed 3
Our Assassin’s Creed 3 test involves a 60 second run through the Boston Harbor. Each run took a similar route, and was repeated five times. When a representative number of frames was found, we used one of those to evaluate the performance you see below.
The GeForce actually gets an extra option for TXAA, but we stuck with Very High for both. We’ll start with Frames per Second, to give you some context:
For your reference, we’ll leave this handy frame time/FPS conversion chart up at the top of each page:
|Frame Time (ms)||16.7||20||25||33.3||50|
The GeForce 660 was the clear winner in Assassin’s Creed, and it doesn’t look like the Tahiti core will help here. To know for sure though, we’ll have to take a close look at the frame times:
Looking at frame times, we see that the GeForce 660 indeed shows quite a lot of consistency, while both Radeons have their issues in certain areas. Settings will have to be lowered to make this playable on either card.
The 99th percentile frame time chart shows us essentially how fast the slowest 1% frames are displaying. This tells us how smooth a game plays even during its most laggy times. In the case of Assassin’s Creed 3, it looks like the 7870 XT performs pretty much exactly like a standard 7870.
Finally, we can look at how much time is spent over a certain threshold. Determining this threshold is completely subjective – one person might never want a game to go below 60 fps, while others are fine if it dips below that occasionally. This is a good way of showing that even when a benchmark runs at a certain “FPS” over the run, it can actually spend quite a bit of time running slower than the average. How much time depends on the game.
We will show as many thresholds as necessary – sometimes a game runs so fast, all results will be zero.
Simply more confirmation that the 7870 XT performs just like the standard 7870 in Assassin’s Creed 3.
