Couldn't run Windows 7, and Windows 10 ran like shit. My old PC basically got a second life with Linux.
This is Half-Life GOTY running on Wine, runs really smooth.
The only downside is lack of directX support, OpenGL is there but the integrated graphics card only supports till OpenGL 2.1, which is not enough for many things, and also slower than directX. Still, my PC feels much faster now, and doesn't scream like a demon whenever I open up a browser :)
(Maybe I should dual boot Win7(While never connecting it to the web), just to play some more games with DirectX?)
Also, my local hospital has started using Ubuntu, their old PCs also couldn't handle the heavy burden of running Windows I guess 🤣
Yess YEESSS! Gabba gabba we accept you, one of us! One of us!
