Amd radeon software crimson edition 16

AMD’s last major update lớn its graphics driver package, Catalyst Omega, added more than đôi mươi features & fixed more than 400 bugs for Radeon owners. Catalyst Omega also turned on FreeSync & Virtual Super Resolution, features that are now household names. AMD also promised that Catalyst Omega would be the first in a series of annual major updates that would add new features and refinements to lớn the company’s driver software.

True lớn its word, AMD’s second major Radeon software release is here—but Catalyst is no more. The company’s driver packages will now be called Radeon Software, and Radeon Software Crimson Edition is the first release under the new name.


Crimson (as I’ll Điện thoại tư vấn it from here on out for brevity’s sake) is more than a rebranding exercise, though. This release offers 12 new or improved features, up lớn 20% higher performance, và tools lớn eke more efficiency out of AMD graphics cards. Alongside the major driver update itself, AMD is introducing a new management utility called Radeon Settings.

AMD boasts of this software’s all-new user interface, better UI performance, improved in-game performance, và higher power efficiency. Those are some ambitious changes, and we’ll see whether AMD accomplished everything on its to-vị menu with Radeon Settings in a moment. For now, let’s see what Radeon Software Crimson has in store for those with the red team’s graphics cards in their PCs.

What’s new

If we were to lớn sum up AMD’s goal for Crimson in one word, it’d probably be stability. The company says it ran twice as many automated kiểm tra cases and 25% more manual kiểm tra cases during QA on Crimson. It also claims to lớn have sầu tested Crimson on 15% more system configurations, including “the latest technologies.”


AMD also polled the community of Radeon users for their trang nhất most annoying bugs, và it claims to lớn have sầu fixed those issues in the Crimson release. Some of the more galling problems that the community brought to light included GTA V crashes on Radeon R9 390X cards, errors related to lớn driver installation on systems with Radeon R9 380 cards, and a Diablo 3 crash in the Desolate Sands area of the game.

FreeSync has learned some new tricks in Crimson. AMD has enabled tư vấn for FreeSync on CrossFire multi-GPU configurations running in DirectX 9 mode for the first time. FreeSync also gets some polish in certain corner cases where the display isn’t receiving frames faster than its minimum refresh rate.

In that situation, và with v-sync on, a feature called low framerate compensation (LFC) will prsự kiện both tearing artifacts và motion judder. With v-sync off, LFC will reduce (but not eliminate) tearing & judder. LFC will only work on FreeSync displays where the maximum refresh rate is greater than or equal khổng lồ 2.5 times the minimum refresh rate.

Crimson is also the first public driver release with AMD’s LiquidVR developer tools enabled. LiquidVR gives devs access lớn tools lượt thích affinity multi-GPU, direct-to-display, latest data latch, và asynchronous shaders. LiquidVR is ultimately meant khổng lồ let devs create a smoother, more immersive sầu VR experience.

Performance & efficiency improvements

Shader Cabịt is a Crimson feature that’s meant to lớn reduce màn chơi load times by storing compiled shaders in a cabít on the system’s hard drive sầu, a technique that could cut load times up to one-third compared lớn older driver versions.


Shader Cađậy could also improve frame time consistency in some cases. We should point out that AMD reached that conclusion by calculating the standard deviation of frame times in its data, a method we don’t recommover.


Frame pacing improves frame-time consistency for graphics cards in CrossFire configurations, and it first made its debut a couple years ago with a driver update for the Radeon HD 7990. That feature gets extended to lớn games running in DirectX 9 mode in Crimson, and to demonstrate its benefits, AMD provided the impressively smooth frame-time graph above sầu. Frame pacing for DX9 could help reduce CrossFire-related microstuttering for popular e-sports titles lượt thích League of Legends & Dota 2.


Another change—& potential improvement—for e-sports players is an optimized flip queue kích cỡ. The Crimson drivers can make use of only a single frame buffer in games where the additional input đầu vào lag generated by triple-buffering doesn’t make sense, lượt thích League of Legends or Dota 2. For an idea of where this optimization takes place, have a look at our handy, if oversimplified, diagram of the frame production process:


Moving to a single buffer, as AMD’s example above sầu shows, can reduce input lag khổng lồ 16.7 ms on a 60Hz display, versus 50 ms with triple-buffering enabled. AMD says this improvement makes mouse và keyboard input more responsive sầu. We don’t see a per-application setting for the flip queue size in Radeon Settings, so we’re guessing that Crimson manages it automatically.

Radeon owners may also see improved performance in general from Crimson. In a best-case scenario with an AMD Radeon R9 Fury X & Crimson, the company says it achieved a 20% improvement in average FPS with the Fable Legends DirectX 12 benchmark running at 1080p. The company’s base results were collected with Catalyst 15.7.1 drivers. We put these numbers lớn the demo using our own Fury X at the same settings & with the same software. Here are our results:





The numbers above are certainly a big improvement over Catalyst 15.7.1. For our own curiosity, we collected a third set of results with Catalyst 15.11.1 at similar settings, and we saw average FPS và frame-time numbers similar to the ones we collected with Crimson. It seems that whatever magic is present in Crimson is also in the wild already with Catalyst 15.11.1. Still, it’s good khổng lồ see that AMD can extract additional performance from its graphics cards with software updates, as we’ve suspected in our past Reviews.

Efficiency is another major theme of the Crimson release, & the road to AMD’s claimed efficiency increases is Frame Rate Target Control, or FRTC. FRTC is supposed to help reduce power consumption when frame rates would otherwise rocket inlớn the multiple hundreds of FPS, lượt thích menus và loading screens.

To curb these apparently wasteful situations, FRTC can be set to cap frame rates at anywhere from 30 FPS khổng lồ 200 FPS, & it can be configured as a global setting or on a per-application basis. With FRTC on, AMD says Crimson can reduce system power consumption up lớn 1.8x. FRTC works with DX9, DX10, và DX11 games under Crimson.
