I have a question referred to the work with a Dual GPU setup. I can see in my trial version that both GPUs are recognized and working in 100%, but the treates frames FPS are not doubled with 2 GPUs in.
The conversion speed is the same with 1 than with 2 RTX GPUs.
If i dont get more speed with 2 GPU cards, why are both on 100%? Dont understand this, its equall what version i test it, even with v3 its the same.
Does TVAI not support multi GPU setup?
Have the same working speed on setting AUTO, then on 1 GPU or all GPUs.
And what is the benefit of using 1 or 2 or more instances?
With multiple instances you can process multiple videos at the same time. If you want to work on one video with two GPU simultanously you might let one instance work on the first half of the video and the 2nd instance on the 2nd half exporting the video to frames. Keep sure you select a different GPU for each instance.
Hello, seen the video. Why you change the wide resolution, does it not function with original resolution?
Is png the best format to store the result? How to convert to video again?
Id like an HEVC 10bit file at last, how do i get there? Do i need other programs more?
Hello, I just changed the size because I wanted to make an upscale. It works with the original width and height too. png stores with lossless compression. That is a benefit over the jpg format but png makes larger files. If you are low on memory or storage space maybe use jpg instead. To make a video file out of the images after processing use the tool of your choice. Vegas Pro can do this for example.
What I find curious is that if I set TVAI’s preferences to “All GPUs,” running process will load both GPUs. And there is some effect on speed, because if you have multiple GPUs that don’t match, the processing speed will be somewhere in between what each will do individually. So what is the app doing with both GPUs on that setting?
It seemed to me that a long time ago 1.x or 2.x worked that way with the RX550s I had at the time, but the folks at Topaz tell me it doesn’t, and mandeunamail up above says that processing is the same speed. So it’s a mystery.
I think the “All GPUs” setting is total crap.
When processing 4 videos (2 in beta / 2 in release version) in parallel, every video has a slightly different filesize.
No clue where this instability is comming from.
Doing the same thing with the beta program set to gpu 1 and the release version set to gpu 2 all 4 videos have the exact same filesize.
The processing speed is about the same in both cases…In fact with “All GPUs” the total system load is about 1660W and about 1850W with each program running on just 1 GPU, so a bit faster.
It really feels like both GPUs just process the same thing without any benefits.
Yes thats the point, on ALL GPU, even the IGpu of my CPU is recognized and trottle al 100% (so 3 GPUs working) while encoding, but the FPS are identical, its the same to have preset AUTO or ALL GPUs or 1 GPU. But all are at 100%, so i dont understand if all are working 100%, why the speed dont change. What are they doing on full trottle?
If this not works, why is the option availible? It seems its only to waste more energy …
Make your own tests, if you consider interesting to report also
There is a speed boost, but it’s smaller than what the benchmark saw. I’d get better results by splitting the video in two and running two instances with each having one GPU all to itself (as the folks at Topaz recommend).
Interesting test, but i see instances zero?
Also would be interesting same GPUs with a modern CPU, think would be much faster.
The IPC of older XEONs are moderate compare to modern sistems, only a personal notice.
It’s actually this: https://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+Gold+6132+%40+2.60GHz&id=3227&cpuCount=2
TVAI benchmark doesn’t display second CPU on dual processor workstations but TVAI does use both of them.
I think these GPUs would just bottleneck a newer CPU. They’re hitting 95-100% utilization with these two now.
And I’ve never figured out what the instances number is supposed to mean…
Iam continuing searching the bottleneck of my system, and reading another post, they speak about the bandwith of the memorycontroller of the CPU, in HWInfo i can see that during encoding in 1 instance, i have ocupped abot 9GB/s - 11 GB/s reading and about 6,5GB7s - 7,5GB/s writing.
And total CPU use about 30-35%.
So is the bottleneck my CPU (memorycontroller), Ryzen 9 7900 (65W) running RAM 6000 EXPO II profil ? … Would a faster CPU solve that bottleneck?
I also have seen that begins with 12fps and after a minute or so iam on 2,2fps in the workflow in normal video enhancing working on 4K, why this brutal drop? … its on v4.2.0
Storage drives? Are they (it) maxed out once that drop happens?
For example, in task manager you can see here that my drive D is maxed out.
This results in a speed drop from over 25fps to about 19fps.
The way the speed is calculated in TVAI, there is a chance that it will be fast when there’s not much going on in the video (Like a long dark fade-in from black). Once there are more colors and motions to process, it can slow down… but not by the amount you mentioned.
Yes i have noticed this when there is less change, it speeds up, but on normal video content y really drops a lot. But the Arthemis Benchmark is about 10fps, so in real life iam running only 20% of it, without any 100% hardware limit to see, really dont understand this …
