Weapon attachments, a more on-the-fly equipment and gear game… Some small QoL items… Honestly aside from getting to ride the hype of a new release there isn’t much to this iteration that “elevates” it beyond KF2. That’s largely why I said it still needs time to cook. If you took everything that KF2 did right and polish the shit out of it, crank it to 11 so to speak, then I could see a full separate release as justifiable. This one is definitely feeling more like a rebase so that they can go even HARDER after micro transactions and battle pass monetization.
I’ve had similarly described visual issues in the recent past on an amd rx 7600xt under Bazzite (based on Fedora 42). It turned out to be the cable was failing. Swapped cables and it hasn’t happened since.
