Issue with CUDA Performance in Redcine-X on RTX 4060

[Javier Goya]

Hi everyone,

-When I select CUDA, playback is choppy, even at 1/16 resolution.
-When I select OpenCL, playback is smooth even at full resolution.
-I have the latest NVIDIA Studio Drivers installed (version 532.03). (and tryed with older ones)
-My GPU is properly detected in Redcine-X:

• CUDA Compute Capability: 8.9
• Memory: 8GB
• Multiprocessors: 24

In DaVinci Resolve, CUDA works fine, reaching around 65-70% GPU usage when applying effects

My setup:​

• CPU: Intel Core i5-14600KF (3.50 GHz)
• RAM: 32 GB
• GPU: NVIDIA RTX 4060
• OS: Windows 11
• Storage: SSD for media playback
• Camera: RED RAVEN

I also tried:

• Clearing cache in Redcine-X
• Setting "High Performance" in NVIDIA Control Panel
• Checking my SSD/HDD speeds (ensuring playback issues weren’t due to disk bottlenecks)

Does anyone know why CUDA is underperforming in Redcine-X? Could this be a software issue? Any suggestions?

Thanks in advance!
