Used unity for my last 3 games and I'm getting really really tired of their shithouse performance over the last 3-4 years. They've gone from constantly making new features, tutorials and systems to barely doing anything.
Engines need constant feature packed updates, not bare bones rubbish. For example there's no DLSS support for URP, it only works in HDRP. There's also "no plans" for it according to the devs, which boggles the mind considering URP is arguably the better platform for mobile, console and regular console gaming.
Game engines should be rapidly evolving and supporting these features, they should take 3-4 years to get commonly implements features or to have to rely on third party plugins to make them happen.
Yeah, I hate that my game is far enough along that it would be... infeasible to restart development in a new engine, but still needs enough work that the uncertainty of Unity is going to be with me for quite some time still.
