XnView Software

Is GPU accleration supported, i bought a new GPU, but don't see much increase in performance using XnView Mp

No

Could you add feature to cache/preload 2-5 next and previous images (relative to the one currently open in full screen mode) to the RAM, this would make switching the images a bit faster.

After purchasing Video Card for my PC i tried few software that support GPU acceleration FastRawViewer and ACDSee, when i scroll with mouse wheel or arrow keys images switch so fast, would love to see similar performance in XnView MP some day.

So far what's your recommendation to achieve better performance with XnView MP, buying a faster CPU will allow faster switching between images?

I currently have i5-4460

From what i understand you already have this implemented, but it loads only one image ahead, how about to allow people with lots of RAM to specify number of images they want to load ahead.

I'll add a number of images setting

Reading ahead, isn't GPU acceleration, unless it is specifically done through the GPU.
It can just as well be done, using the CPU and regular RAM.

How many CPU coreas/threads are supported? If i get 12 cores 24 threads CPU will all of them be used?

ImageGlass 9 Final now has Hardware Acceleration (uses .NET 8.0 and WebView2 too!)

Tried that and i did not like the interface and fact you need to install some additional frameworks. But most importantly it was not that much HW accelerated, seems like that viewer only accelerate the zoom and pan, the image loading speed when you switch images is slower than with XnView.
Seems like HW acceleration only works for < 16MP images.

Performance improvements

Image interaction is significantly improved in ImageGlass v9.0 beta 1 thanks to hardware acceleration (GPU). You can see and feel it when performing zooming, panning action. However, it still has some limitations: only non-alpha pixel format can be rendered with GPU, and the maximum image dimmension for GPU rendering should be less than 16,380 pixels.

As mentioned above, I also need to load multiple images into the cache in advance.

When I compare several adjacent images, they switch slowly, which troubles me a lot.

If I could choose to add multiple images to the cache, the process would be much more comfortable.

I run into a real annoying situation if i have folder with ten 90MB DNG files that have no thumbnails and say its a focus bracketing shot and i am trying to find the best focused image out of ten.

When i switch between DNG files it takes a while to load each file beyond any reasonable time.

Is it possible to have option for:

1. keeping preview for already loaded DNG/RAW file in memory until for instance one navigates to another folder or until xnviewmp is closed then memory cache can be cleared.
2. to allow generate temporary previews for all DNG/RAW files inside currently open folder are keep this previews in memory until user left folder or until xnviewmp is closed. This opposed to switching between every DNG/RAW file and waiting 10 seconds for each to be loaded user can press that button and load all files while he go make a coffee.

Could changing your Tools > Settings... > Formats -- Camera RAW viewing size while previewing possibly help?

The thing is i want to have full res RAW file preview generates so i can compare quality and detail see if things are in focus.
