Basic functions and severely-low performance

Greetings. I just installed CachyOS with Wayfire as a compositor, which appears to mean no file manager is included to the point of not being able to open any compressed archives, not even .xz or .bz2, support for which are required to install 7-zip and Firefox respectively because that’s how they’re compressed. I attempted to install these without the terminal or package manager because I understand they are updated faster from the official websites and there’s only a python script of 7-zip there. Furthermore, the icons and text on the top bar are slightly cut off on their right side and the bottom bar appears to have icons that can’t be customized. That is, there doesn’t seem to be a way to pin or remove program shortcuts to it and search results appear to lead to a completely different compositor. But what seems to be the biggest issue of all is that Youtube playback at 720p and up on this Ryzen 2400g drops frames when it could handle 4k without that under Windows. I was not able to test under stock Firefox due to the aforementioned archive issue. On a side note, for some reason, Cachy Browser deletes all downloads upon restart. Furthermore, Waydroid doesn’t connect to the internet and nothing about ports or restarting sessions appears to apply.

I don’t know what program within the package manager handles archives. The ones that I installed from there didn’t work. Since all programs I wanted to try out from github are stored in compressed archives, I couldn’t use them. I tried to install the Heaven Benchmark application, the .run file gave some kind of ‘required terminal not found’ error. ChatGPT was not able to generate a working way to open it. Cachyos appears to not be compatible with most Linux applications so far. However, I was able to run simple WebGL benchmarks from webglsamples.org. The Aquarium one hovers around 24 fps under the maximum load. No results are published for that, so I couldn’t compare against the performance other people were getting with their 2400Gs.
I had decided to install Firefox from the repos and got better performance on Youtube, but the dropped frames issue wasn’t completely solved. However, there is no difference in WebGL performance based on the aforementioned benchmark.
Installed Zoom, the package appears to be incomplete and it just isn’t listed in the programs list.
