New Radeon Software Crimson ReLive Driver

Radeon Software Crimson ReLive Edition 17.4.1 has just been released by AMD. Download links for all versions are towards the bottom of the Release Notes page.

Here are the two big "new" things that the ReLive driver supports and both are specific to Vive and Oculus VR gaming.

Support for Oculus' Asynchronous Spacewarp (ASW) on Radeon R9 Fury series, Radeon R9 390 series and Radeon R9 290 series graphics products. ASW compares previously rendered frames, detects the motion between them, and extrapolates the position of scene components to create a new synthetic frame. This technology helps avoid dropped frames and can provide an overall smoother VR experience on the Oculus Rift.

Support for SteamVR Asynchronous Reprojection on Radeon RX 480 and Radeon RX 470 graphics products on Microsoft Windows 10. Asynchronous Reprojection reduces judder to provide an overall smoother and more comfortable VR experience on the HTC Vive.

I will tell you assuredly that I have had extensive experience with VR and AMD GPUs in the past six months, and Asynchronous Spacewarp and Asynchronous Reprojection are surely two welcomed technologies when it comes to "improving" your VR experience. That said, when you are putting out the big bucks on your VR rig, and it will be big bucks, the last place you want to skimp is in the GPU department. While both the technologies above are targeted for making your VR experience "better," it is without a doubt that your goal should be to NEVER be in any kind of Reprojection or Warp of any kind, no matter whether you are using a Red or Green GPU. These technologies are stop-gaps in making your VR experience "not as bad" as it could be. Never think that these technologies are making your VR experience better. If you are not hitting the 90 frames per second / 11.1 millisecond frame render time, you are getting a substandard VR experience.

We are expecting new GPUs from AMD here very soon, and that will give us reason to once again delve back into VR gaming and start building the new HardOCP VR Leaderboard. It has been several months since we have done VR gaming coverage, and since then new GPUs have launched, drivers have matured, and along with those hopefully so has the VR gaming experience for AMD and NVIDIA.

While certainly we are looking forward to new Polaris GPUs in the middle of the stack, the big bad Vega is what we really want to get our hands on.

Issues that have been fixed in this driver are notable as well, certainly the Wildlands multi-GPU scaling.

Fixed Issues

  • Display flickering may be experienced on some AMD FreeSync displays when running applications in windowed borderless fullscreen.

  • Radeon Settings install may become stuck or unresponsive when doing a driver upgrade through Radeon Settings.

  • Tom Clancy's Ghost Reconآ® Wildlands may experience poor Multi GPU scaling on some Multi GPU enabled system configurations.
