About this mod

This is a simple batch file that allows you to easily upscale images 4x by dragging them onto the .bat file using RealSR ncnn Vulkan.

Permissions and credits
This is a simple batch file that makes it easy to upscale multiple images using RealSR ncnn Vulkan.

Normally, you would use it via the command console, but this saves some typing by allowing you to drag and drop image files onto a .bat file. 

I'm not really much of a super user and I'm not an expert in upscaling, so there are probably a lot of areas for improvement. This was just a simple activity for me because I was bored and I figured I would share in case anyone else is interested in trying out upscaling. 

As a general warning, I would not recommend regular users to run random batch files they find online unless it's from a source they trust. 

Usage Instructions:

1. Download RealSR ncnn Vulkan and extract it somewhere (e.g., C:\RealSR)
2. Download this batch file and place it in the folder from step one (should be in the same folder as "realsr-ncnn-vulkan.exe")
3. Place any images you want to upscale into the same folder as above
4. For DDS files (skyrim textures), the program may be able to upscale them directly but it may not. I'm not an expert so I don't really know why, but I would assume it's based on the compression used (e.g., BC7 or BC1 or whatever).
To work with these, save the texture you are using as a png (I use for this)
5. Select the image(s) you want to upscale and drag them onto the batch file. You should see a prompt next to your mouse show up that says "+ Open with auto upscale 4x.bat" while hovering over the batch file. 
6. You'll see the command line open and the progress as a percentage. If you don't see this, something went wrong.
7. Your new 4x upscaled textures will be saved in the same folder as "OUT_[whatever your original file was called].png"
8. Resave as a DDS file similar to what was done in step 4

u/VRNord on Reddit for posting a guide on how to upscale that got me to do this in the first place.
