(And also, I'm pretending Macs don't exist for this statement. They aren't even PCs anymore anyway, just giant iPhones, from a silicon perspective.)
To anyone actually paying attention, igpus have come a long way. They are no longer an 'I can play minecraft' thing.
I hadn't realized that "Arc" and "Integrated" overlapped, I thought that brand and that level of power was only being used on discrete cards.
I do think that integrated Arc will probably be killed by this deal though, not for being bad as it's obviously great, rather for being a way for Intel to cut costs with no downsides for Intel. If they can make RTX iGPUs now, and the Nvidia and RTX brand being the strongest in the gaming space... Intel isn't going to invest the money in continuing to develop Arc, even if Nvidia made it clear that they don't care, it just doesn't make any business sense now.
That is a loss for the cause of gaming competition. Although having Nvidia prop up Intel may prove to be a win for competition in terms of silicon in general versus them being sold off in parts, which could be a real possibility it seems.
Wait, RDR2 is badly optimized? When I played it on my Intel Arc B580 and Ryzen 7 5800X, it seemed to work pretty well! Way better than almost any UE5 title, like The Forever Winter (really cool concept, but couldn't get past 20-30 FPS, even dropping down to 10% render scale on a 1080p monitor). Or with the Borderlands 4 controversy, I thought there'd be way bigger fish to fry.
