I read a different review to Eurogamer that said the day 1 patch made no difference to performance. I can grit my teeth for the stuttering but it's having to use a controller that's the issue for me
I'm utterly hopeless with controllers, so I play every game with mouse/keyboard. I'll be doing the same in Elden Ring, I find that what control method you are used to is usually the important thing, I tend to be equally as good with a mouse and keyboard on games as people with controllers are but yeah I can understand why you wouldnt want to use a controller.
