This might be of help: Tweaking Settings - #4 by GAZA350
@Grabber523 seems of poste lots of really helpful tips - which I intend to follow.
Your post is of interest as I am about build a new PC with an i5-12600k - but using my old GTX1660 Super until (if) GPU prices are more affordable.
I have seen a few people using the same card that get reasonable performance by ensuring they correctly adjust settings to full just short of max CPU and GPU loading.
Also see: which others seem to of found useful.
Would be really interesting to hear how you get on.
