Direct X 12 vs Direct X 11 in Ashes of Singularity Beta

Welcome, today we are looking at the difference between two different API’s in the game Ashes of Singularity. Ashes of Singularity is a next generation real time strategy game.  This game supports both Direct X 12 and Direct X 11. Direct X 12 is only available to those running Windows 10 and have a Direct X 12 compatible GPU.

Test Setup:

CPU: AMD FX 8320@4.9ghz

Motherboard: Asrock Extreme 9

Ram: Team Xtreme DDR 3 2400mhz 8gbx2(16gb) (10-11-10-32-1T)

GPU: XFX R9-290 DD @ 1125mhz core/ 1500mhz memory

HDD: Mushkin Chronos Deluxe 120gb SSD , OCZ Vector 256gb SSD, and  2x Seagate 2tb ST2000DX001

Driver: AMD Driver Packaging Version
15.301.1201-151223a-297971C

Benchmark: In game benchmark

First Up Direct X 11

Now for Direct X 12

dx12_1

Well holy smokes Direct X 12 doubled the average framerate.  Built into the benchmark you can see the driver overhead. Direct X 11 struggles with driver overhead, and it also looks like the CPU performance is handicapped with this API.

So let’s dive into Cpu performance a little more. Below is a chart based on core scaling in both Direct X 11, and Direct X 12.  Does Direct X 12 allow more cpu cores to be used? This is achieved by disabling cores in the bios. The base clock speed will remain the same.

Results:

Clearly the API advantage of Direct X 12 shows. With only 2 cores enabled in bios Direct X 12 outperforms Direct X 11 with 8 cores by around 31%.  Overall it looks like the game scales up to 4 cores in both Direct X 11 and 12.

Conclusion:

Game performance on my platform is vastly superior in Direct X 12. I mean anytime you double your performance without a hardware upgrade is remarkable. Remember this is the same game, same settings, the only change in the game was booting the game in Direct X 11 or Direct X 12.  This clearly demonstrates just how limiting past API’s have been. Direct X 12 is the future and the future looks bright for PC gamers.
