We went with a fairly mid-range platform, similar to what a lot of mainstream gamers use to play on. The survey of hardware and software configurations for Steam users, presently the largest PC gaming platform, offers us a view of the most prevalent gaming setups in use (data from December 2016) :
- Windows 10 64-bit representing 49% of the market
- 8GB RAM is common across 33% of gamers (our configuration has 16GB)
- Full HD resolution (1920x1080) is used by more than one-third of gamers (38%, actually), while 25% remain at 1366x768, likely on laptops. QHD (2560x1440) is used by fewer than 2% of gamers, and 4K is just anecdotal.
- Quad-core CPUs are used by 48% of players. Our configuration employs a mid-range quad-core Intel CPU.
Graphics Card Choices
We're testing with six different graphics cards, most of which land in the mid-range category.
The Radeon RX 480 “Core” from XFX is at a disadvantage, given its stock clock rate, compared to Asus' GeForce GTX 1060 Strix OC operating at 1645 MHz. We overclocked the AMD card +4% to the level of a higher-end model, yielding a GPU frequency of 1340 MHz and a memory clock of 2 GHz.
These two cards are entry-level for the mid-range. AMD's Radeon RX 470 could have an advantage with its additional gigabyte of memory. It certainly won't go wasted in Resident Evil 7.
The GTX 970 and R9 390 are a generation old, but remain widely used by PC gamers who bought in when they were still modern. We chose them more for their popularity in gaming machines than their price (which is quite variable).
Test Procedure
All measurements are collected using PresentMon and a custom front-end written in-house, which facilitates a number of sensor readings as the performance results are generated. Check out PresentMon: Performance In DirectX, OpenGL, And Vulkan for more information about our methodologies.
In order for graphics card performance to be truly representative of reality, we take care to warm each contender up prior to taking measurements. The majority of cards operate at higher boost frequencies initially. Then, as the GPUs get hot, their clock rates fall somewhat and eventually stabilize. Benchmarks run in the interim convey better-than real-world frame rates.
We therefore let the game run for five minutes to warm up the card, then we record its performance during the test sequence. Again, the measurements are taken at Full HD resolution with all options set to maximum, HBAO+ active, and anti-aliasing set to FXAA+TAA. Each test runs twice, activating and deactivating Shadow Caching for a purpose we will see later on.
