Hi,
I found out that using my Nvidia Quadro A4000 Gigapixel AI produce more blurry images, also they are offset down by ~2pixels, compare to original (bicubic scale) or processing with CPU or intel GPU.
So I made some tests using CPU, Intel GPU HD 630 and Nvidia Quadro A4000 using low and medium memory settings, but since difference between low and medium not so noticeable, will only post all 3 images with medium memory settings.
Other settings used are : AI model Standard, Suppress noise and remove blur 50, Reduce color bleed and Face refinement are OFF.
On provided examples it is clearly seen that using CPU and Intel GPU Gigapixel scale and process the image, but using Nvidia Quadro it is scale, but not process image or process is not so good (sharpening, removing blur and so on)
My PC config is CPU i5-8500, 32GB of RAM, Nvidia Quadro A4000
Gigapixel AI 5.6.1 Trial with enabled model downloading (models were downloaded before processing images).
Edited:
Observations I found. When using old version of Gigapixel 4.4.5, images processes by Quadro A4000 looks much better than on new version 5.6.1. They very close to the images processed by CPU and iGPU.
So something broken on new version.
You are not using the Quadro 4000 according to that info. Have you set it in your preferences? You can select it from the list … how much Video RAM does your Quadro 4000 have?
Note that the Intel i5 is a minimum requirement along with a GPU that has 2GB of dedicated vRAM. The HD630 integrated GPU has 127MB and uses up to 1.5GB of system RAM.
Did you read my first post or just replying some random stuff ?
I can set in Gigapixel settings what to use as AI processor and it is processing with selected device. Just the result is different for CPU or build in GPU versus Nvidia Quadro.
No, you don’t read, as all you current question is already in my first post.
The settings are the same for all AI processors. The amount of RAM for iGPU is enough, it’s not crashing. The amount of RAM on Quadro A4000 is 16GB.
Again, try to read the first post, using iGPU and CPU Gigapixel produce good image without issue.
The main problem, that using Quadro it’s made more blurry image, not so crisp than using CPU or iGPU.
Also did tests with high, CPU and iGPU is very good images, Quadro is more blurry and offset down by 2pixels.
Main GPU is set to iGPU and it’s the one connects to monitor, Quadro is second one and has no monitors connected to it. So Gigapixel will always show my “main GPU” in graphics info, but can use the one I selected in settings.
This is the best setup when you do a lot of Machine learning with python or using programs such as Gigapixel, so your desktop is not freezes during training or image processing.
How possible that such stupid person become a tester.
In my previous reply there is a screenshots where it’s selected and also did I say that it doesn’t work with Nvidia Quadro ?
I’m only trying to say and show, that processing with Quadro is not so good as with CPU or iGPU.
What a surprise, I saw here on the forum that older versions process images better than the new one. So I took the one from a friend, which told me about this product, and indeed, with version 4.4.5 Nvidia Quadro does good images, without offset down by 2pixels and not so blurry.
So it’s the issue with new version of the product.
