I have an Alienware 18 with a NVIDIA GeForce RTX 4080 Laptop card. I have never been able to use Unifab AI because of how slow it was. Today I was happily surprised the the latest version of UniFab now is able to use 100% of the GPU, and drastically increase FPS. (I’m getting 17.82 FPS)

The output of an old DVD upscaled and then AI processed to HDR10 is AWESOME and doesn’t take a week to do it . Kudos my friends at DVDFAB !!!!!

Thank you very much for your recognition of UNIFABAI, there are times when the graphics card is not fully turned on and running, and you need to set up the graphics card to run at full capacity, so that you can greatly speed up the processing speed of UnifabAI.

How do you optimize the GPU? My machine: I9, Windows 11, RTX 4800. I’m testing the updated HDR10 on version 3.0.1.1. A 31 minute 4K movie source is running at GPU 12% and 1.74fps. It’s been running for over 4 hours. Performance like this is not practical or useable.

I also tried a 4K 50 minute source for HDR10 and the process halfway through stalled at .01fps and to take 600 hours to complete. I had to cancel the operation going nowhere.

We sincerely appreciate you choosing our product! Your feedback is invaluable for improving our software.
Thank you for your feedback. We’ve assigned a technical specialist to investigate the issue and will provide you with an update soon.

By the way, did you mean RTX 4080 instead of RTX 4800?

I just started another 2.01 hour black and white movie using HDR10 high quality that is 4K source. CPU at 10%, GPU at 13%, FPS is 3.89. Time to complete 12 hours and 28 minutes. 12 hours is too long considering GPU usage minimal. Looking at it now GPU is fluctuating between 6 and 20% but FPS stays at 3.89. Remains to be seen if the process doesn’t stall at some point.

I9, 32GB RAM, RTX 4080.

2.01 hour black and white movie using HDR10 high quality that is 4K source.

Right now about 40 minutes into processing the GPU is fluctuating between 9 and shoots up to 30% for a short time and back down but FPS is down to 1.94 and time to complete is up to over 23 hours.

Seems if I leave the HDR processing in the back round and do other work on the PC using Lightroom and Affinity Pro Photo it interferes with Unifab performance to where FPS drops to the 1.94 mentioned in previous message and completion to over 20 hours. I cancelled the operation and tried EncodeGUI (which is free) and setup HDR with the same input and the same thing happens. Performance degrades if I work in Lightroom and Affinity.

I cancelled the EncodeGUI process and started from scratch closing Lightroom and Affinity and letting EncodeGUI run the process with no other back round usage on the PC.

So, here’s a point I’m trying to make, If I start Unifab HDR with the same input (and running no other software on the PC) FPS and completion time with EncodeGUI is about half Unifab at 7.2 FPS and about 6.5 hours to completion.

I own Topaz Video Ai but their Hyperion results are terrible. For this reason I was hoping Unifab HDR would be better. For absolute best results HDR-X Studio is the way to go but the license/pricing structure is geared more towards professionals.
