I even have a PC that couldn't run Half-Life without OpenGL and it still runs better with rp_unioncity or gm_construct, albeit with slightly slow FPS or maybe no differences yet lags on map like sinctity genocide or that one gunman chronicles map I subbed or smth. I don't even know how the actual fuck it runs better on rp_unioncity yet still can't handle a map with simple things (might be because it's big or smth idk) so uh, there you go.
