Hi, You get a Steam key when you buy on Itch. Moreover, when you buy it on Itch I get more money. The updates are automated on both Steam and Itch, they are always published at the same time. AMD GPU should be working but only on experimental branches.
The demo has an old version that won’t work with AMD GPU. If you want to try it before buying, you can either wait for the 3.1 to be released in the stable (and therefore play it in the demo) or download the demo and do this:
- download https://github.com/ggml-org/llama.cpp/releases/download/b8121/llama-b8121-bin-win-vulkan-x64.zip
- open AIdventure’s folder
- Remove everything inside the llamacpp folder
- Extract everything from the zip you downloaded into llamacpp folder of the game 3.1 The extraction might put everything inside a folder named llama-8121-bin-win-vulkan-x64 ; make sure just get the files from this folder.
