Its not just DLSS being better.I've been having to use dlss bit more now my card is aging, and I flicked obsessively between fsr and dlss and found dlss better, would I pay high premium extra for it no , but would I pay like £50 more yes
If AMD really want to change mind share they need to offer something really really good, not just good , the upscaling/ RT that's one reason they price lower but they need to be more aggressive unless they can also catch up with them features
From my experience Nvidia drivers are more reliable, and playing games, some older ones too, just offers a smoother, trouble free experience, particularly on day one launch of a game.
Also from my experience, their cards are built better and last longer, I have had and seen multiple AMD cards die before or shortly after warranty. My last 2 Nivida cards, being a GTX 670 and GTX 1060, have both lasted many many years beyond their 3 year warranty, both being heavily overclocked too. Look at many AMD cards for sale on OCUK NEW!, not having a 3 year warranty, but sometimes 2 or even 1 year!, and this is not open box, this is NEW product!, even the makers have little faith in their lifespan...
AMD cards tend to always use more power and run hotter, which fits with the above, and tending to have a shorter lifespan...
