After Effects 2026 - RTX 5090 (Blackwell) Performance Issues
I am experiencing severe performance issues in After Effects 2026 with my brand new high-end system. Even on very small and simple projects, the software freezes, lags, and has render problems.
My system specs:
- After Effects 2026 (latest version)
- Windows 11 64-bit
- NVIDIA RTX 5090 (Driver 580.97)
- AMD Ryzen Threadripper 7970X 32-Core (4.00 GHz)
- 128 GB RAM
Issues I experience:
- Preview window freezes when pressing spacebar
- Program freezes when adding effects
- Render queue freezes even on small projects
- Mercury Playback Engine GPU Acceleration (CUDA) renderer is grayed out and cannot be changed
- GPU usage stays at around 1% during freezes — this is clearly not a hardware performance issue
Steps I have already taken with no improvement:
- Clean NVIDIA driver reinstall using DDU
- Disabled Multi-Frame Rendering
- Cleared all media cache and reset preferences
- Adjusted preview quality settings
- Updated all Adobe applications to latest versions
This system is extremely powerful and should handle After Effects with no issues whatsoever. Based on my research, this appears to be a known compatibility issue between Adobe software and the new NVIDIA Blackwell (RTX 50 series) architecture. There are multiple threads on this forum reporting the same problem.
I kindly request Adobe to prioritize a fix for RTX 50 series GPU compatibility. I will also be sharing my log file in the replies.
Thank you.
