I replaced my RTX 5090 with an ASUS TUF RTX 4090 OC, and now, regardless of which model, resolution, or codec I use, outputs renders are succesfull but all videos contains nothing but black frames.

I then uninstalled v1.7.2, manually deleted Topaz folders under ProgramData, Program Files, and AppData Local + Roaming, and performed a completely fresh installation including model downloads → same problem.

At that point, I suspected the NVIDIA drivers might be responsible, so I tried Studio drivers, Game Ready drivers older versions, but none of them made any difference.

The obvious conclusion would be that the graphics card is defective…but how could that be, 3DMark Speedway give me over 10.000 points and other benchmarks/stress tests runs perfectly fine without any graphical artifacts or errors.

I’ve now put my RTX 5090 back in the system. I could have tested whether the same issue occurs with v1.7.1 or an older version, but honestly, I’d run out of patience by then.

Has anyone else experienced this issue or have any idea what might be causing it?

I regularly swap GPUs for testing purposes, mainly around my own application, but I still use Topaz alongside it.

I also work with different GPU architectures and configurations, from single-GPU setups to multi-GPU systems involving up to five RTX 3090s or two RTX 4090s.

Although I’m not running exactly the same version as you, I’ve encountered some pretty serious issues during these hardware swaps, many of which ultimately pointed to NVIDIA drivers.

One thing I’ve learned from experience is that **identifying a proven, reliable driver version for each GPU generation and software configuration can make a significant difference.**

The latest driver is not necessarily the best choice. In fact, I’ve found that chasing the newest releases can sometimes introduce more problems than they solve.

Given that you’ve already tested several driver versions, I wouldn’t rule out an issue specific to how Topaz handles the RTX 4090, either.

I’d suggest asking an AI to research which NVIDIA driver versions have proven the most stable with Topaz, based on known issues and user feedback reported across forums and other online sources.

You might also want to try a completely clean driver installation rather than simply updating. NVIDIA leaves registry entries scattered all over Windows, which can sometimes cause issues when swapping GPUs.  
This worked fine for me.
