This mainly applies to those of you who are running on a Windows PC. However I do have some limited information for MAC users at the end of this post.
Adobe updated Premiere CC to version 2015.3 and with this new version, they dropped support for older “legacy” video cards. These cards include:
GTX-200 series and mobile versions
GTX-300 series and mobile versions
GTX-400 series and mobile versions
GTX-500 series and mobile versions
GTX-600 series and mobile versions
Quadro FX series and mobile versions
Quadro CX, 200, 2000, 4000, 5000 and 6000 and mobile versions
Even though some video cards are still on Adobe’s “approved” list of video cards, they are no longer working correctly when having CUDA enabled in the Mercury Playback Engine with Premiere CC 2015.3. So disregard what Adobe has listed on their website as to what video cards will work with Premiere as it is out of date with the Premiere 2015.3 release.
Initially, Adobe was telling users to roll the video card driver back to an earlier version. However, that doesn’t make any difference for the vast majority of users who are experiencing problems getting their “legacy” video cards to run with CUDA enabled.
Adobe now consider these to be “legacy” video cards and you should not look for Adobe to provide support for these video cards.
If you have one of these video cards, Adobe is now telling people they need to upgrade the video card or to roll back to version CC 2015.2 of Premiere.
The cards that are being reported as working fine with Adobe Premiere CC 2015.3 are:
GTX-700 series and mobile versions
GTX-900 series and mobile versions
GTX-1000 series and mobile versions (GTX-1080, GTX-1070, etc.)
Quadro M series and mobile versions
Quadro K series and mobile versions
Some people are reporting problems using CUDA with a legacy video card. Right now, the fix is to remove CUDA and run the video with OpenCL. While it may be slower, it is not as slow as running with no GPU acceleration at all.
