Adding to Radeon Software Crimson Edition’s enhancements for DirectX® 9, DirectX® 10, and DirectX® 11, Radeon Software 16.9.1 enables multi-GPU frame pacing support to DirectX®12 on all GCN-enabled GPUs and AMD A8 APUs or higher with GCN.

 

Frame pacing delivers consistency by increasing smoothness in gameplay. In multi-GPU (mGPU) configurations, GPUs render alternating frames and push each frame to your screen. Each render can be created at various speeds causing differences in frame time. With frame pacing enabled, frames are distributed evenly, i.e. with less variance between frames, creating liquid smooth gameplay.

A number of games currently take advantage of frame pacing in DirectX®12. Total War™ – Warhammer®, Rise of the Tomb Raider™ and the 3DMark® Time Spy benchmark also show smoother run-throughs.  

 

Let’s look at the some real-life scenarios:

 

 

 

 

 

With Radeon’s DirectX® 12 frame pacing enabled, the Radeon™ RX 480 delivers up to 35% lower 99th-percentile frame times in Rise of the Tomb Raider™ at 2560x1440 with Radeon Software Crimson Edition 16.9.1 pre-release driver.1

 

 

 

 

 

 

 

 

 

 

With Radeon’s DirectX® 12 frame pacing enabled, the Radeon™ RX 480 delivers up to 37% lower 99th-percentile frame times in Total War™ - Warhammer® at 3840x2160 with Radeon Software Crimson Edition 16.9.1 pre-release driver.2

 

 

 

 

 

 

 

 

 

 

With Radeon’s DirectX® 12 frame pacing enabled, the Radeon™ RX 480 delivers up to 44% lower 99th-percentile frame times in 3DMark® Time Spy at the 1440p Default preset with Radeon Software Crimson Edition 16.9.1 pre-release driver.3

1. Testing conducted by AMD Performance Labs as of August 19th, 2016 on two Radeon™ RX 480s, on a test system comprising Intel i7 5960X CPU, 16GB DDR4-2666 Mhz system memory, Radeon Software Crimson Edition pre-release driver 16.9.1 and Windows 10 x64 using the game Rise of the Tomb Raider version 1.0 build 647.2_64 at 2560x1440 and very high preset with Direct X® 12 frame pacing enabled. PC manufacturers may vary configurations, yielding different results. Radeon Software Crimson Edition 16.9.1 pre-release driver running Rise of the Tomb Raider DirectX®12 on two Radeon™ RX 480 with frame pacing enabled delivers 99th percentile display change frame times of 15.9 ms vs.99th percentile display change  frame time of 24.5 ms with frame pacing disabled, which is 35% lower 99th-percentile frame times. Performance may vary based on use of latest drivers. Test results are not average and may vary. RS-62
