False hopium. ARC is what it is. We have been told the hardware is nerfed.
My experience is that older games are a crapshoot. Arkham Knight would not launch for me without DXVK, then I saw the same issue exists on the MSI Claw. A problem that is more than 2yrs old now. My old DX 8.1 game would not get past GPU detection. Crysis and some of the other older games like AC:Black Flag require compromises other IHVs do not. And even then a 1050ti would run them better. The list goes on.
Even when the driver notes say an old game has been radically improved, frame pacing can be trash. And I would run into this weird thing where every time there is considerable draw distance is some games, fps would tank. I could get most games I tried running well enough to enjoy them, but again an old AMD or Nvidia card would play them better wiht zero hassles.
