Older Radeon models face crossfire issues; fix implemented.
Older Radeon models face crossfire issues; fix implemented.
In the end, it looks like I discovered a fix for the Radeon 6xxx lineup (especially dual GPUs) by turning off crossfire in the newest 16.2.1 Crimson updates. This allowed me to use just one GPU. For details on the challenges I faced, check out the link provided. If you need clarification or want a simpler version, feel free to ask. I followed the latest driver release and expanded certain DLL files as suggested.
Here’s a summary of the steps I took:
- Disabled crossfire in the latest Crimson drivers.
- Used the most frequently needed DLLs for games like DX9 titles.
- Installed the newest AMD Crimson drivers for older cards.
- After updating, CSGO (DX9) ran smoothly without crossfire issues.

Crimson issues have been resolved with this approach. All recent and older titles run smoothly by copying a DLL file into the game directory. The process functions similarly to installing updated Radeon drivers for specific games. The DLLs provided are from the 15.11.1 version. For example, Batman Arkham Knight performs optimally on [Guru3D] with AMD Catalyst 14.12, Dotnet45 on Windows 8.1 64-bit. For that title, you must expand files from AMD's 14.12 drivers. Overall, the 15.11.1 version has supported most games except Fallout 4, which works best with the specified AMD and Windows setup.
CSGO is merely one instance. In fact, many games running DX9 (possibly DX10) face freeze and flickering issues. The game may stop working entirely. This solution applies to all those titles, not just CSGO. Some enjoy crossfire or Sli on CSGO, while others think it causes microstutters and disrupts gameplay. It's a matter of personal preference. I choose it because it distributes the workload roughly to half of each GPU, which might be due to a CPU bottleneck (p.s.) rather than just relying on one GPU at full capacity and using a loud fan to cool it down.
Long ago, I struggled to locate the steps for extracting DLL files. The attached links should help now. You can simply download the driver from AMD's site, extract it, and look for the DLL names in the folder.
