While thats definitely true for many games it’s less relevant for console makers and its hardly true universally; definitely not true for the insomniac games I mentioned.

Plenty of games are coming out that are optimized very well. Unfortunately, UE5 has gotten way too popular and devs often don’t seem to really know how to optimize games developed on the engine. Kinda the downfall of having an engine that appeals so much to artists but not so much to engineers. I think the only remotely well optimized game I can think of that was made in UE5 is Hellblade 2. And even as impressive as that game is from a technical standpoint (nothing can fix how boring it is) I still have stuttering problems with it. Though my rapidly aging R5 2600 is not helping things there.

But there are still impressive PC games out there. Recently Doom The Dark Ages, indiana Jones, and Kingdom Come Deliverence 2 come to mind as games that are impressively well optimized on PC. Especially KCD2, that game feels like black magic to me.

I think this is less of an issue of cost cutting by devs and publishers, though it’s definitely a factor, and moreso just devs not being as knowledgeable about optimizing games as they used to be.
