I have downloaded Topaz Denoise AI and am using it occasionally. I find that it does a very good job but takes forever to render an image. I have, what I thought, was a reasonably robust system but it still takes several minutes to process an image form a 24 MPixel camera. Is anybody else finding this to be the case as well? As a result, I resort to using it on only my noisiest images.

It is slow and seems to get slower the more 'work' it has to do on an image. I have never had it exceed one minute in processing time. Seems much longer when you are waiting .

When I have time to wait or when I really want an image I still use Topaz Focus AI. I'm probably one of only 2 or 3 people on UHH who still use it.

I personally use plugins when, (a) they can it faster than I can; (b) they can do it better than I can or (c) when I want to play with an image.

It is really intended to be used on noisy images rather than normal workflow. Also, it should be the first process you apply to our image and best to use on RAW files and output RAW files. FWIW, I have found improved outcome when I have a jpeg image to process to first convert the image to RAW using JPEG to RAW program. And yes, it does take a couple of minutes to process, but wow the results are impressive.

I used this program on several photos I was processing this afternoon. I didn't find it particularly slow. I don't think it was taking more than 30 seconds to process a file. This program does a great job of enhancing detail in addition to removing noise. I was very pleased with the results.

Yes, true. You should see how long it takes with a 46Mp image.

That’s pretty much what Topaz’s own publicity says. I would not be surprised if you can speed it up by getting a hard core “gamer” graphics card. Not inexpensive and me might require a power supply upgrade

Gigapixel AI is the same story -but when you really need it ....

The DeNoise program is not slow. In fact, none of their AI programs are slow.
The BIGGEST factor determining the time it takes is your computer - not the size or noisiness of the image. I just ran a photo taken with my D850 (DeNoise settings were 70/35/10) and it was rendered in approx. 20 seconds. Without getting technical - Topaz clearly states that the AI programs need a lot of your computer's resources. Short of buying a new computer - try shutting down everything else when you're using their AI programs.

Also go to Topaz Preferences and turn off your graphics card. Often it will speed things up

I have found Topaz DeNoise AI to do an excellent job on SOME pictures, an average job on others - and - ADD A LOT OF NOISE to some others!!!!!

The program indeed is slow, even with a fast processor, a good NVIDIA video card (lower end gaming) and 16 GB RAM!!!

I was considering purchasing DeNoise AI, but inasmuch as I very seldom have any/much noise, I can't even come close to doing so.

I have used it an it was pretty fast.

The fact that many answers differ as to the speed of the program should tell you that it's not the program … it's the computer. Also, Topaz has stated that the results will vary with each photograph. I have seen this myself - some photos clearly benefit from the AI programs, others not as much. I just bought a big "Kick-ass" (that's the non technical term) computer and am processing my D850 photos in under 30 seconds and I would bet you that the DeNoiseAI program I am using is the same as yours. I'm not sure exactly which components of the computer do the work but I do know at least two the will affect the rendering speed - Processor and video card; I've got an Intel Core i9-9900K CPU @ 3.6Ghz unit and an NVIDEA GeForce GTX 1080Ti. Also a SSD and plenty of memory.

When I first tried Giga pixels and Denoise AI it took over 30 minutes for it to complete When I checked my video card it had only 2 gig My Pc is home build and 5 years old
I went on line and did some checking on what I needed and they suggested 6 gig so i ordered a video card with 8 Gigs installed it and now Giga pixels and
De noise completes in about 5 sec and my Memory is still 16 gigs and that is on a average 25- 30 MB picture

Of course, I recognize that many factors enter into the performance of any software, especially when involving graphics processing – not the least of which is the file being processed. Most of the pictures I worked with in my testing were taken (some RAW, some JPG) with my Canon EOS 70D and Canon G16. Others were from other sources – including examples of noisy files from Topaz!

I was simply trying to make the point that the no, the program is not slow - it's the computer. I used the fact that many answers say it's slow and many answers say it's not slow. The program is the same for all of us, the difference between us is our computers. Your statement that the "Program indeed is slow, even with a fast processor, a good NVIDEA video card …". I don't want this to turn into the definition of what is "Fast". I am not denying that the process can take close to an hour (like on my old computer), I just think it's plain wrong to say that the Program is slow (blame the program) … unless you add the words "on my computer" - That would be a correct statement. Trust me, you'd like working on my computer.
