As DirectX 12 gains more and more momentum moving forward, companies are releasing patches for their popular DirectX 11 titles bringing DirectX 12 support. Today we’ll be seeing what the two APIs offer on Hitman.
So far, the DirectX 12 transformations at least on the side of AMD were all connected to a power gain. At least for the most part. Rise of the Tomb Raider on the other hand saw performance drops from both NVIDIA and AMD when moving to DirectX 12. Ashes of the Singularity which gives the first serious comparison between DirectX 11 and DirectX 12 sees a larger focus on the implantation of Asynchronous Shaders. The end result is a leg up for the AMD line of cards as they come out ahead.
While DirectX 12 support was offered from the start for Hitman. Not all is smooth for AMD graphics cards with Tonga and FIJI based GPUs as a 60 FPS limiter is seen. To avoid this, a second monitor must be connected with a refresh rate that is above the FPS the graphics card can achieve. For 1920 x 1080 and 2560 x 1440 we use the ASUS MG279Q.
To remove other problems under DirectX 12, “RenderTargetBitmap Reuse” must be disabled. Our test system today is our standard graphics card one which consists of an Intel Core i7 3960X @ 3.9 GHz on an ASUS P9X97 Deluxe with Corsair h110i GT AiO water cooling system. A total of 16 GB of DDR3 RAM is used while storage comes for an OCZ Arc 100 240 GB. Finally, we use a Seasonic Platinum Series 1,000 watt PSU housed in a Fractal Design Define R5. Our operating system is Windows 10 64-bit while graphics card drives are AMD Radeon Software Crimson Edition 16.3 and NVIDIA GeForce 364.51.
The following results were obtained here:
First of all, it must be noted that graphics cards from AMD behave slightly better in Hitman when compared to their NVIDIA counterpart. At times we see even the Radeon R9 390X come out ahead of the GTX 980 Ti. In terms of a performance increase, it’s clear that the R9 390X is one card that benefits strongly from the new API with gains of 10 to 15 percent. The R9 Fury X sees gains of around 5 percent while the R9 380 sees numbers that are within the range of fluctuation.
NVIDIA cards on the other hand tend to see a slight performance drop when moving to DirectX 12. Because of this, users are probably better off sticking with the slightly faster DirectX 11 API.
Overall, you can’t shake the feeling that Hitman has the potential to offer more as we see some GPUs benefit more than others. We’ll of course keep an eye out for updates in the coming months.
